2.1 Busways and High-occupancy Vehicle Lanes The history of bus infrastructure in the U.S. is intertwined with the development of high-occupancy vehicle (HOV) lanes. If one computer or peripheral should fail when using bus topology, the rest of the network is not affected by this change in performance. United States, Phone: 202-366-4052 Some network lengths of bus lanes in major cities, listed by buses per km of bus lane): The busiest bus lane in the United States is the Lincoln Tunnel XBL (exclusive bus lane) along the Lincoln Tunnel Approach and Helix in Hudson County, New Jersey, which carries approximately 700 buses per hour during morning peak times an average of one bus every 5.1 seconds. The feasibility of this approach and cost savings associated with not paving the center-lane area will depend on local construction costs and practices. The Avenida Jimnez corridor of Bogots TransMilenio system represents a high-quality example of merging urban regeneration with a BRT system. Bus topology isnt a reference to vehicles. Plan and section view of Stretch 1 at a width of 25.5 meters. Counter-flow bus lanes are used in various conventional bus systems around the world (Figure 22.40). Multiple peripherals can be supported through bus topology. The related term busway describes a roadway completely dedicated for use by buses. In this city-center location Curitiba, Brazil, is able to segregate the busway to the side of an existing railway. 4. Under normal operating conditions, a driver will require a road width of approximately 3.5 meters to safely maintain position within the lane, and 3 meters at the station, since the driver will slow down to pull adjacent to the boarding platform. In addition to reducing the number of stops, citing stops so as to improve service (as discussed below) can be a component of a BRT project. It is clear to see that small networks that require a temporary solution benefit from the advantages and disadvantages of bus topography. Grade separation can also be an option to consider bypassing difficult terrain or water (Figure 22.26). The location of the segregated busway within a specific roadway is a design decision that offers more options than might be immediately apparent. Transit malls permit a maximum number of customers to access shops and street amenities. Additional devices slow the network down. This design choice is due to two factors: (1) Limited road space (two lanes in each direction) and limited right of way; (2) Relatively light mixed-traffic levels. Stop spacing affects both access time and line-haul time, and therefore affects the demand for transit service. In 1956 Nashville became the first city to implement on-street bus lanes. A central file server is used instead of hubs and switches, which means there are fewer points of potential failure that must be managed with this setup compared to others. The traffic light will have a separate public-transport vehicle phase allowing the BRT vehicles to leave the virtual lane, move into the general traffic lane, but before the rest of the traffic is allowed to go, so that the lane is relatively free-flowing. Similar to the bi-directional, one-lane configuration, a virtual busway is a single bus lane in the middle of a roadway used by both directions of travel. Single-lane operation can be an option to consider in such situations. They may be long, continuous networks, or short segments used to allow buses to bypass bottlenecks or reduce route complexity, such as in a contraflow bus lane.[12]. Business Hours:8:30 a.m.-5 p.m. That is why the size of these networks is naturally limited. There are advantages and disadvantages to each location (see table). Bus topology would be much more efficient if the computers on the network could coordinate with one another regarding transmission times. That is the disadvantage. In such cases, the transit mall creates a calmed street environment void of traffic congestion. Charging will be an issue. Otherwise, accidents can occur, or the system will dampen the usefulness of the public space. The new device connects to the linear bus topology and becomes part of the network immediately. Grade separation can also be an option to consider bypassing difficult terrain or water (Figure 22.26). Such corridor segments are typically employed in central areas where space restrictions limit the ability to share space between both public transport and private vehicles, but can exist along an entire corridor, such as the Orange Line in Los Angeles, USA. [53] In other words, for the bus mode, it represents the summed length of bus lanes operational in a certain region. Wiring terminators take no power requirements. b) Provide extra provision for light. 6. Additionally, since busways do not require vehicle lane changes, some system developers have elected to not pave the center of the lane (Figure 22.23). Signing of bus lanes and other forms of priority to particular road users are also discussed. The lack of mixed traffic encourages an environment friendly to pedestrians and street activity. The 1970s inaugurated an era of vigorous development of busways and other HOV facilities. [21], In the Netherlands mixed bus/cycle lanes are uncommon. One-way busways in the median of a one-way street are awarded even fewer points and one-way busways that run alongside the curb of a one-way street fewer still. Quito briefly utilized counter-flow movements for its Ecova corridor since its only available vehicles possessed doorways on the wrong side. In order to reach a destination we tend to take short routes to reach faster. Sight distance is obscured for crossing vehicles stopped to the right of the bus. Smaller goods can typically be delivered at any time by carts and delivery services operating from the pedestrian area (Figure 22.35). In this case, the mixed-traffic operation has a negligible impact on system performance. Earlier straddling concepts. In either case the problem is preventing illegal parking or standing. One way of substantially reducing the delay to a bus reentering a traffic stream after a parking lane, curbside stop is to adopt a priority merge rule. Increasing the number of nodes that are present on the network has a direct impact on the quality of communication that occurs. Physical guidance systems are employed on BRT systems in Adelaide, Australia; Bradford, United Kingdom; Essen, Germany; Leeds, United Kingdom; and Nagoya, Japan. In all cases, the physical terrain and base materials must be considered for their engineering appropriateness for tunnels or elevated structures. Bus lanes can become ineffective if weak enforcement allows use by unauthorized vehicles[23] or illegal parking. Thus, an engineering and cost-feasibility analysis should be conducted whenever grade separation is being considered as an option along certain BRT corridor segments. The location of the segregated busway within a specific roadway is a design decision that offers more options than might be immediately apparent. If for some reason the driver does not re-engage physical steering, a mishap may occur. Because it is so expensive to build grade separations, it is usually done in strategic locations where the separation greatly improves operations. Since 1963, New York City has been using a system of bus lanes that are intended to give priority to buses, which contain more occupants than passenger and commercial vehicles. This paper considers the way in which bus priority can be given using traffic signals, either by pre-programming traffic signals in an area traffic control scheme, or by giving priority at individual signals when buses are detected by transponders carried on the buses. Satellite offices and other small network areas can benefit from a permanent installation of this type as well. There are a few benefits for experienced cyclists in riding in the bus lane. This makes it easy to install a simple LAN at virtually any location where networking would be beneficial to a department or working group. Assume an average passenger vehicle occupancy of 1.1, and a discharge headway of 2.5 seconds per vehicle. Thus, transit malls typically reside in locations where shop sales are quite robust. For areas exclusively for trams, see. One section of Lima, Perus BRT, with a single lane for mixed traffic in one direction, and two lanes in the other direction. Pedestrians can be unaccustomed to looking in the direction of the counter-flow lane, and thus cross unknowingly into a dangerous situation. [11], Bus lanes may be located in different locations on a street, such as on the sides of a street near the curb, or down the center. Many roads lead to the path, but basically there are only two: reason and practice. The paved strips for non-guided buses will likely be wider than the strips for guided buses, since non-guided buses will be subject to more variation in lateral movement. The benefits of bus lanes are that they:. Over time there is a tendency for additional stops to be added to bus routes, as requests for service in front of more places are accepted. As dwell time is reduced, optimal spacing will narrow. Efficient layout of interior spaces, with consideration to inclusion of off-vehicle. A T-connection failure immediately limits access. As the speed of the feeder mode is increased, optimal spacing will widen. A bus gate consists of a short section of road that only buses and authorised vehicles (typically taxis) can pass through. 7. Plan and section view of Stretch 5 at a width of 49 meters. The guideways prevent any turning movements, and thus the vehicle can technically be operated hands-free (Figure 22.24). Each streets design depends on the local circumstances. Attempts have been made to quantify benefits in terms of passenger time-saving, operational savings and bus regularity. 3. [10], The El Monte Busway between El Monte and Downtown Los Angeles was the first dedicated busway in the US, constructed in 1974. That size limitation also increases the risk that collisions will occur within the bus topology because communication spacing is at such a premium. For a four mile trip, the cumulative delay can be in excess of ten minutes. Bus termination issues can lead to network issues. The section characteristics include: Following are the typical configurations for BRT corridor design to consider in the conceptual design phase and that should become the basis for the detailed engineering. Whether adapting a manufactured shelter or using a custom design, some general factors to consider include: Giannopoulos, G., Bus Planning and Operation in Urban Areas: A Practical Guide, 1989. Exclusive busways or bus lanes were implemented on the Shirley Highway in the Proponents of cashless business models, however, say that the benefits outweigh any potential inconveniences. b). This weakens the exclusivity of the road space, which in turn leads to higher rates of peak-period violations, and hence should not be encouraged. All Rights Reserved. Curitiba, Brazil, uses center lanes, both lanes on the side, and streets exclusively for BRT (Figures 22.9, 22.10, and 22.11). Upon opening, the 7-mile (11km) busway featured specialized stations, signal priority, grade separation, and was expanded to 14 miles (23km) by 1980. If the link is congested, then this choice will have a detrimental impact on travel times, system control, and the overall system image. stops, existence of car turning lanes, and bus reserved lanes. As for disadvantages, bus topology makes it difficult to determine a network problem if the entire system goes down. Bus bulbs are a section of sidewalk that extends from the curb of a parking lane to the edge of the through lane. Report 19, Guidelines for the Location and Design of Bus Stops. Private vehicles retain some form of direct access to corridor properties. That also places the entire network at-risk should something happen to that cable. However, the Plaza del Teatro segment of the Quito Trolebs avoids this problem by physically separating the pedestrian area from the busway. Many systems, however, operate in mixed traffic at precisely the areas where dedicated infrastructure is needed, that is, downtowns where there may be a lot of congestion. Thus, merchants are able to move large goods during the late evening and early morning hours. Thus, short and selected points of mixed-traffic operation can likely be tolerated without undermining the functionality of the entire system. The shelter design should have a common and consistent look across the BRT system, but with allowance for differences to permit stations to harmonize with the local urban fabric, perhaps referencing the history of the area. A transit mall in the central district of Pereira, Colombia. That means security options are difficult to install on such a setup because everyone can see what everyone else is doing. Citizens raised several concerns about traffic congestion, lack of awareness among drivers and road users, lack of streetlighting, bus breakdowns in the bus lane causing bottlenecks, absence of lane discipline, and narrow roads, among other things. Descriptive text such as "BUS LANE" may be marked prominently on the road surface, particularly at the beginning and end. Terminators are required by ISO 11898 to be at the two extreme ends of the network, which tends to be the controller node and the node which is furthest away from the controller. Otherwise, the added bus dwell time variability from a near side stop would complicate, if not preclude, bus detection and green phase extension. The introduction of the rule in May 1999 was accompanied by a "Yield to Bus" public awareness campaign. [6] The first contraflow bus lane in the UK was introduced in King's Road, Reading as a temporary measure when the road was made one-way (eastwards to Cemetery Junction) on 16 June 1968. This option is also not likely to be viable in systems with high vehicle frequencies and high customer demand. A dedicated bus lane may occupy only part of a roadway which also has lanes serving general automotive traffic; in contrast to a transit mall which is a pedestrianized roadway also served by transit. Because it is not scalable and the costs increase over time, however, it may not be the best choice for those who anticipate growth occurring within their network. Bus lanes may be demarcated in several ways. Rouen, France, has successfully implemented a virtual busway. Peripherals and computers can be added to the topology of the network in a linear fashion without the same demands for cable length that a star topology link would require. Private cars, motorcycles, and trucks are banned either entirely from the corridor segment or during public transport operating hours. The failure of one station does not affect the rest of the network. However, this configuration receives only half the amount of points under the Busway Alignment metric of. A slight trench in the roadbed has also been used reasonably successfully in the Netherlands for short sections. In 1948, the East Side Trolley Tunnel in Providence, Rhode Island was converted to bus-only use and became the first dedicated busway in the United States, continuing to operate to this day. Although bus topology is cheaper to setup, the costs of maintaining this network are higher in the long run. A section of median queue-jump lane in Cape Town, South Africa. Increased Safety and Walkability for Pedestrians. Some of the findings of optimization studies are: Although analytical studies to determine optimal stop spacing provide some useful guidelines, stops must ultimately be sited to serve major trip generators and attractors in the service area. The loss of on-street parking and direct customer access by private vehicles may also be a worry for some merchants. Painted information employing a bus-only approach is also an option, as shown here from an example in Jakarta, Indonesia. For dedicated median bus lanes, BUS ONLY pavement markings (MUTCD 3D-01) emphasize the lane and deter drivers from using it. These stops must be fully accessible and lead to safe, controlled crosswalks or other crossings. In some instances, access to the queue-jump lanes by general traffic is only restricted during peak periods, that is, general traffic may utilize these lanes during the out-ofpeak periods. [57], Bus lane on Gloucester Road in Hong Kong, with the words "bus lane" painted in English and "" in Chinese, Bus lane of the pioneer Rede Integrada de Transporte in Curitiba, Brazil, Bus lane in Church Street, Parramatta, Australia, Highway bus lane on Gyeongbu Expressway in South Korea. The impact of such a design is not just on the performance and operational control, but also on the psychological image of the system. A grade-separated busway receives maximum points under the Busway Alignment metric of. Perhaps the greatest challenge in making transit malls and other transit-only corridors work is access for delivery vehicles and local residents. Office of Research, Demonstration and Innovation, United States Department of Transportation, Coordinating Council on Access & Mobility, Low and No-Emission Vehicle Federal Technical Assistance, Federal Register Notices & Rulemaking Documents, Annual Research Reports / Reports to Congress, Zero Emission Research Opportunity (ZERO), International Public Transportation Program. Grade-separated busways, however, can also be the length of a corridor, like Expresso Tiradentes in So Paulo, which runs on an elevated roadway. JavaScript required, but not enabled. A section of curbside queue-jump lane in Cape Town, South Africa. At grade zebra crossing: Advantages of At grade Zebra crossing: a) Not require extra cost. The rule is typically advertised on the rear of buses. In addition to the different roadway configurations, system designers can opt for either with flow or counter-flow bus movements. The BRT Standard awards no points for this configuration under the Busway Alignment metric, as curb lanes rarely function as intended. In some instances, local contractors may not be well-versed in utilizing this construction technique. A single station reduces infrastructure costs in comparison to the construction of separate stations for each direction. The linear nature of the network means that each unit transmits to the backbone and that data is then available to the other units that remain connected. Curbside bus lanes often fail due to traffic congestion and poor enforcement (New York City). Individual device issues can also be difficult to troubleshoot, which means it is not a great setup for larger networks. The chief advantage of splitting the route is the impact on mixed traffic, parking, and truck deliveries. Curb extensions enhance pedestrian safety . Cities such as Bogot and Quito, employ bus-only corridors in selected locations. Generally speaking, there are three factors which account for bus delays: delays resulted from interaction of buses and other vehicles in mixed traffic conditions, delays at intersection/junction due to traffic signals, and delays at bus stops (dwell time) resulting from boarding/alighting passengers and bus-bus interfaces at stops (Jacques and According to the Sustainable Safety guidelines they would violate the principle of homogeneity and put road users of very different masses and speed behaviour into the same lane, which is generally discouraged.[22]. However, given that the paving of the busway represents perhaps the single-highest cost item in system infrastructure, any potential cost savings should be considered. If a roadway is bordered by green space (e.g., a large park), water (e.g., ocean, bay, lake, or river frontage), or open space, then there may be no turning conflicts for long distances, in which case side alignment may actually be preferable to median alignment. The road surface may have a distinctive color, usually red, which has been shown to reduce prohibited vehicles from entering bus lanes. ET, M-F. However, a one-way transit mall can operate on as little as three meters of space, as is the case with the Plaza del Teatro segment of the Quito Trolebs. [18], Entire streets can be designated as bus lanes (such as Oxford Street in London, Princes Street in Edinburgh, or Fulton Street in Downtown Brooklyn), allowing buses, taxis and delivery vehicles only, or a contra-flow bus lane can allow buses to travel in the opposite direction to other vehicles. A BRT system can operate in mixed traffic for certain segments of a corridor. In some cities, such as The Hague in the Netherlands, buses are allowed to use reserved tram tracks, usually laid in the middle of the road and marked with the text "Lijnbus". If the backbone is damaged for some reason, it can either cause the entire network to fail or have it split into two networks instead of one. Direct-service systems can be found in Pittsburgh, Pennsylvania, USA; Guangzhou, Lanzhou, and Changzhou, China; Ottawa, Canada; Cleveland, Ohio, USA; and a growing number of cities around the world. Figure 1. Otherwise, these schemes would likely be less viable. These advantages will be linked with the advantages offered by the use of transit signal priority. Routers, printers, and other data devices can be connected to this network in addition to computers or terminals. A two-way busway that runs on the side of a one-way street is awarded fewer points. Pedestrian (s) stepping from the bus stop (horseplay). Bus lanes may also be physically separated from other traffic using bollards, curbs, or other raised elements.[14]. Center-running bus lanes avoid the problem of private vehicles blocking the lane by double parking for loading of passengers or cargo. The Oregon version of the rule reads as follows: The Florida version of this rule applies only to buses stopped at "a specifically designated pullout bay." With protected bike lane street designs, traffic speeds are lowered, so when collisions do occur, they are far less likely to be fatal, and this protects everyone. 6. It may be that bike lanes themselves only change the overall theme of a street to via calming, I would be hesitant to claim a difficulty in finding a positive impact. The size and scope of bus topology is naturally limited. On 15 January 1964 the first bus lane in France was designated along the quai du Louvre in Paris and the first contraflow lane was established on the old pont de lAlma on 15 June 1966. They do not coordinate, however, which means multiple transmissions can occur simultaneously and this creates heavy network traffic with a high potential of data loss. Maintenance costs are higher. In theory, there is no limit to the number of nodes that can be added to the backbone of this system, though additional units come with the risks of slow data speeds and quality issues can be encountered. In some special cases of lower demand and good technology, a short stretch of narrow busway could be operated with a single lane. Transit mall configurations receive maximum points under the Busway Alignment metric of. In this city-center location, Lima, Peru is able to segregate the busway to the side of an existing roadway. These lanes, while lacking some features of "true" BRT, capture the essence of the concept, featuring dedicated bus lanes, covered stations, and detailed maps. Buses use mountains of tires over a relatively short usable lifetime when compared with rail-based transportation systems. The primary advantage of bus topology is that it makes linear connections much easier to complete. Proceedings of the 34th Australasian Transport Research Forum, 2830 September 2011, Adelaide. Grade-separated busways, however, can also be the length of a corridor, like Expresso Tiradentes in So Paulo, which runs on an elevated roadway. Curb extensions (also called bulb-outs) extend the sidewalk into the parking lane to narrow the roadway and provide additional pedestrian space at key locations; they can be used at corners and at mid-block. However the experiment proved so successful that it was made permanent for use by motor buses. The initial reason was to save the expense of rerouting the trolleybus, which was due to be scrapped on 3 November of that year. 3. Greater benefits can be achieved if signal control is combined with appropriate traffic management measures. Some merchants desire round-the-clock delivery access, which is both a political and technical obstacle to implementing a transit mall. Many transit agencies tend to locate bus stops at the near side of intersections (1). Also, this type of configuration often mirrors the existing bus routes, and thus is potentially more acceptable to existing operators. Conditions on the Oxford Street corridor in London have become difficult due to the fact that pedestrian volume exceeds the provided footpath space. Through the denser city center area, the Guayaquil Metrova system utilizes a split-route configuration, with each direction of travel being provided on parallel streets. the disadvantages is that you might arrive at the bus stoplate, get on the wrong bus, miss your stop, or your stop not be in the bus route.. It is notable that, once a scheme has been put in place, traders are often the main people to voice a desire to extend its boundaries or period of operation. Transit-only corridors, though, are not just restricted to central business and shopping districts. The installation of bus lanes requires additional space to either be constructed (increasing the impact of the road on the surrounding area, and possibly requiring taking of private land),[55] or space must be taken from existing lanes, reducing that available for vehicles. A typical road diet technique is to reduce the number of lanes on a roadway cross-section. Speed advantages of guided busways are only realized when the distances between stations are quite significant, Self-enforcing as general traffic is unable to utilize the busway, Difficult for recovery vehicle to remove stranded bus from the guideway, Permanence of busway, as roadway cannot easily be opened to mixed-traffic operations, Ongoing maintenance of bus guidance wheels on bus front axle. The use of vandal-resistant and graffiti-resistant materials. In addition to the speed issues that occur with a larger network using bus topology, there are data quality issues that must be considered. With flow means that the vehicles operate in the same direction as the mixed traffic in the adjoining lanes. A median busway in Bogot with a single median station has become the standard for high-quality BRT systems. The first bus lane is often erroneously attributed to Chicago, where in 1939 Sheridan Road was installed with reversible lanes north of Foster Avenue. 2. One of the most common applications of a road diet is to improve safety or provide space for other modes of travel. The segregated lane is what allows customers to develop a mental map of the system in their minds. Transit Cooperative Research Program. Drivers are not actively seeking an alternative mode of travel. If the link is congested, then this choice will have a detrimental impact on travel times, system control, and the overall system image. Breaking Down Bus Rapid Transit Lane Options. In Pittsburgh, Pennsylvania, USA, entire roadways are devoted exclusively to BRT operation. One option to eliminate merging delay is to restrict parking during peak periods. The difference is that the buses take turns in using the lane by direction and set by the need for queue jumping within the corridor. BRT projects can also involve adding limited-stop service, perhaps overlayed over existing service. This can increase the speed of productivity because instead of sending commands to a centralized network, a command can be sent directly to the needed peripheral. Lyndon, S. Marinelli, P.A. The BRT Standard awards full points for a median busway alignment. The public transport system thus operates as two one-way pairs. Plan and section view of Stretch 5 at a width of 38.5 meters. 3. Non-motorized delivery systems, as shown here in Santiago, Chile, can help make transit malls viable for local shop owners. In general, there is a tradeoff between: (a) closely spaced, frequent stops and shorter walking distance, but more time on the vehicle and (b) stops spaced further apart and longer walking distance, but less time on the vehicle. They are used by buses, trams and taxicabs. Not paving the center of the busway, like this example in Eugene, USA, may produce infrastructure cost savings as well as reduce operational noise. Guidance systems also provide other advantages, such as safer vehicle operation and higher operating speeds. Until a concerted effort is made to reduce carbon . In addition to a reduction in bus merging delay at each stop, other significant benefits of a priority merge rule include: reduced waiting times for passengers at bus stops due to reduced irregularity of the service, decreased travel time for passengers, less stress on bus operators, and less impact on bus operations due to traffic congestion. As the bus approaches the intersection, it will move into the virtual lane. Allows construction of lanes without paving the center strip, which can be grassed to give green and softer appearance.
