[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. Signing of bus lanes and other forms of priority to particular road users are also discussed. As of May 2021, there are 138.4 miles (222.7 km) of bus lanes within New York City (with an additional . This permits effective use of these priority measures to clear the bus through the intersection with minimal delay. The terminators that are used for most bus topology systems are passive devices. Intersections along a side-aligned busway can be problematic, but can be dealt with by using traffic signals and roundabouts. With flow means that the vehicles operate in the same direction as the mixed traffic in the adjoining lanes. BUS LANES - THEIR PROBLEMS AND ADVANTAGES 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. 7. In 2020, there were 438.4 km of bus operational infrastructure per million inhabitant for the metropolitain region of Montral.[54]. While it is typical to find conventional bus lanes at the curbside, it is rare for BRT to place the busway on the sides of the roadway. The guideway allows for hands-free driving on the Nagoya-Yutorito Line. A break in the backbone can cause an entire network to collapse. Bus Rapid Transit (BRT) is a high-quality bus-based transit system that delivers fast, comfortable, and cost-effective services at metro-level capacities. A corridor may have multiple configurations over its length. The bus proceeds in the general traffic lane until the virtual lane is once again dedicated to its direction of travel, usually upon approaching the intersection. Find a library where document is available. The introduction of the rule in May 1999 was accompanied by a "Yield to Bus" public awareness campaign. Likewise, optical or magnetic guidance systems are also possible. Thus, an engineering and cost-feasibility analysis should be conducted whenever grade separation is being considered as an option along certain BRT corridor segments. Theyre made of resistors and capacitors, which means there isnt a power requirement that must be met. Transit Malls and Transit-Only Configurations, Bus-only or transit-mall corridors are effective options in giving complete priority to public transport. Extensive discussion and guidance for determining proper bus stop location for a given site context are provided in both Giannopoulos and TCRP. 3. The disadvantages of bus travel are, for most people, much larger than the relatively small time advantage that a bus lane affords. FINAL Advantages and Disadvantages of Reversible Managed Lanes January 2010 Atlanta Regional Managed Lanes System Plan Georgia Department of Transportation, Office of Planning -3- Safety Reversible facilities require additional safety precautions when compared to their bi- It is a network setup that involves computers and network devices. 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. The exclusive, priority lane given to a BRT vehicle is the principal physical feature that sets it apart as a higher-quality form of transport. The location of the segregated busway within a specific roadway is a design decision that offers more options than might be immediately apparent. BRT projects can also involve adding limited-stop service, perhaps overlayed over existing service. [further explanation needed], CityTransit Data[52] is a website procured by the UITP that contains statistics about, among other things, the "length of dedicated PT [public transport] operational infrastructure" for each mode. A near side stop would also prevent effective use of a queue jumper lane (with or without an advanced bus signal) since the adjacent queue of through traffic would already be discharging from the stop line by the time the bus was ready to depart from the near side stop. Terms of Use and Privacy Statement. b). In operating a vehicle along a guided busway, the driver does not actually have to steer the vehicle. A section of median queue-jump lane in Cape Town, South Africa. The median location also permits a central station to serve both busway directions. Counter-flow is sometimes used if the doorways on the existing buses require the bus to drive on a certain side. A third hazard for pedestrians arises where bus lanes are completely separate lanes whose layout is totally unrelated to the rest of the road network, because then you have buses travelling in unexpected or surprising directions which can be an additional hazard for pedestrians. Counter-flow systems are generally not employed in BRT systems, particularly due to concerns over pedestrian safety. However, if a vehicle is physically restrained by a guidance mechanism, then a lane width of 3 meters is possible. Bus termination issues can lead to network issues. Each streets design depends on the local circumstances. The road surface may have a distinctive color, usually red, which has been shown to reduce prohibited vehicles from entering bus lanes. This may, however, pose a safety challenge for nighttime freight deliveries in some areas and should be addressed properly. 4 Benefits of Protected Bike Lanes Greater Safety, Reduced Accidents & Injuries. Stretch 1 is located along the waterfront and its typical cross sections varies from 25.5 meters at station locations to 21.5 meters in between stations. [7] In October 1971 Runcorn opened the world's first bus rapid transitway. The quality of the data is placed at-risk on large bus topology setups. The reason for the point drop is a concern for safety as pedestrians are unlikely to expect traffic to come from the opposite direction. Charging will be an issue. Curb extensions enhance pedestrian safety .

ET, M-F. For a traffic flow of 700 vphl, and a critical gap size of 10 seconds, the bus merge delay is 24.2 seconds. In particular, very busy streets like main thoroughfares can be a lot more hazardous to ride in even when using the bike lane, so the bus lane . 6. Transit mall configurations receive maximum points under the Busway Alignment metric of The BRT Standard, since they constitute a fully exclusive right-of-way, completely separated from mixed traffic. During peak hours not only are more buses often required because of increased demand, but as buses get stuck in congestion and take much longer to complete their routes, even more buses are needed on the network to limit the gaps between services. [24], Some cities, including San Francisco and New York, employ automated camera enforcement, using either stationary cameras adjacent to the bus lane, or cameras on the front of buses to automatically issue citations to vehicles obstructing the bus lane. However, many cities, specifically in the developing world, have wider lanes and higher fatality rates (See Figure 1). The first bus lane is often erroneously attributed to Chicago, where in 1939 Sheridan Road was installed with reversible lanes north of Foster Avenue. While it is typical to find conventional bus lanes at the curbside, it is rare for BRT to place the busway on the sides of the roadway. What Are the Disadvantages of Bus Topology? The Avenida Jimnez corridor of Bogots TransMilenio system represents a high-quality example of merging urban regeneration with a BRT system. 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. In the United Kingdom bus gates are common in towns and cities. [5], On 26 February 1968 the first bus lane in London was put into service on Vauxhall Bridge. Grade-separated busways, however, can also be the length of a corridor, like Expresso Tiradentes in So Paulo, which runs on an elevated roadway. 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 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. Curitiba essentially tailors the roadway configuration to the particular situation on the given road segment. It is cheaper than other network options. In the cases of Pittsburgh and Brisbane, the busways run along corridors with significant green space. A two-way busway that runs on the side of a one-way street is awarded fewer points. Such conflicts can sometimes be resolved with the establishment of nearby parking garages and access during non-operating hours of the public transport system. [19], Some locations allow bicyclists or taxis to use bus lanes, however where bus or bicycle volumes are high, mixed traffic operations may result in uncomfortable conditions or delays. Allows construction of lanes without paving the center strip, which can be grassed to give green and softer appearance. 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. That means it cannot be used as a stand-alone solution. Bus lanes are a key component of a high-quality bus rapid transit (BRT) network, improving bus travel speeds and reliability by reducing delay caused by other traffic. 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. Extensive discussion and guidance for determining proper bus stop location for a given site context are provided in both Giannopoulos and TCRP. 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. Quito briefly utilized counter-flow movements for its Ecova corridor since its only available vehicles possessed doorways on the wrong side. Providing public transport vehicles with separated facilities up to the flyover will allow them to jump the queue with little detriment to overall travel time. These lanes, while lacking some features of "true" BRT, capture the essence of the concept, featuring dedicated bus lanes, covered stations, and detailed maps. Bus stop spacing has a major impact on transit performance. Instead of having a "jump" on the queue of traffic in the adjacent through lanes, the bus would have to merge with it. A median busway in Bogot with a single median station has become the standard for high-quality BRT systems. Peak-only bus lanes may be in effect only in the main direction of travel, such as towards a downtown during morning rush hour traffic, with the buses using general purpose lanes in the other direction. These advantages will be linked with the advantages offered by the use of transit signal priority. Please check your browser settings. These stops must be fully accessible and lead to safe, controlled crosswalks or other crossings. 2 Dedicated bus transit lanes require median boarding islands in the roadway at each stop. In some special cases of lower demand and good technology, a short stretch of narrow busway could be operated with a single lane. A median station permits customers to select multiple routing options from a single station platform. Curitiba utilizes a variety of roadway configurations. 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. A virtual busway stop located in the middle of the roadway. The guideways prevent any turning movements, and thus the vehicle can technically be operated hands-free (Figure 22.24). Bus lanes are frequently in effect only during the peak hours in the peak direction. Washington, DC 20590 Not paving the center of the busway, like this example in Eugene, USA, may produce infrastructure cost savings as well as reduce operational noise. The lack of mixed traffic encourages an environment friendly to pedestrians and street activity. Multiple peripherals can be supported through bus topology. Plan and section view of Stretch 1 at a width of 21.5 meters. Single-lane operation is used most notably in Eugene, Oregon, USA (Figure 22.37). In this city-center location, Lima, Peru is able to segregate the busway to the side of an existing roadway. Share sensitive information only on official, secure websites. A key to choosing this type of alignment is the absence of access to development along a particular corridor edge, i.e., a park, an airport boundary wall, etc. Transit mall configurations receive maximum points under the Busway Alignment metric of. Breaking Down Bus Rapid Transit Lane Options. To end this thesis one will evaluate the previous described bus lane types and their influences on traffic, this will be done by Therefore, mixed-traffic operation is awarded 0 points under the Busway Alignment metric in. Upon opening, the 7-mile (11km) busway featured specialized stations, signal priority, grade separation, and was expanded to 14 miles (23km) by 1980. That is because it requires less cable length than the other network options. Side-Aligned, Two-Way Busway Configuration. [17], Peak-only bus lanes are enforced only at certain times of the day, usually during rush hour, reverting to a general purpose or parking lane at other times. Attempts have been made to quantify benefits in terms of passenger time-saving, operational savings and bus regularity. In Pittsburgh, Pennsylvania, USA, entire roadways are devoted exclusively to BRT operation. A transit mall in the central district of Pereira, Colombia. To the degree that a BRT is emulating a light rail system, a useful benchmark is the actual stop spacing of LRT systems in the U.S. (see table). [10], The El Monte Busway between El Monte and Downtown Los Angeles was the first dedicated busway in the US, constructed in 1974. Figure 1. Security options are limited with bus topology. The use of vandal-resistant and graffiti-resistant materials. This report presents the findings of three interrelated before and after studies of the effect on safety of the implementation of with-flow bus lane schemes. The through lane may be blocked during peak periods by queuing buses, Increases sight distance problems for crossing pedestrians, Minimizes conflicts between right turning vehicles and buses, Provides additional right turn capacity by making curb lane available for traffic, Minimizes sight distance problems on approaches to intersection, Encourages pedestrians to cross behind the bus, Requires shorter deceleration distances for buses, Gaps in traffic flow are created for buses re-entering the flow of traffic at signalized intersections, Intersections may be blocked during peak periods by queuing buses, Sight distance may be obscured for crossing vehicles, Stopping far side after stopping for a red light interferes with bus operations and all traffic in general, May increase number of rear-end accidents since drivers do not expect buses to stop again after stopping at a red light, Minimizes sight distance problems for vehicles and pedestrians, Passenger waiting areas experience less pedestrian congestion, Requires additional distance for no-parking restrictions, Encourages patrons to cross street at mid block (jaywalking), Increases walking distance for patrons crossing at intersections, Decreases the walking distance (and time) for pedestrians crossing the street, Provides better sight lines to bus patrons waiting for the bus, Provides additional sidewalk area for bus patrons to wait, Segregates waiting bus patrons from circulating pedestrian flow on the sidewalk, Results in minimal delay to the bus and its on-board passengers by reducing bus merge delay, Provides additional space for amenities including bus shelters, Can cause traffic to queue behind a stopped bus, thus causing traffic congestion, May cause drivers to make unsafe maneuvers when changing lanes in order to avoid a stopped bus, Costs more to install compared with curbside stops, particularly for addressing street drainage requirements. The freed-up space is then used to provide or enhance some of the following features: In British Columbia, the rule applies only on roadways with a speed limit of 60 km/h (37 mph) or less and also specifies that a driver must only yield when it is safe to do so. Thus, short and selected points of mixed-traffic operation can likely be tolerated without undermining the functionality of the entire system. Single-lane operation can be an option to consider in such situations. [50] In contrast, the Cross-Harbour Tunnel in Hong Kong carries 14,500 buses per day,[51] or an average of about 605 an hour all day (not just peak times), but the bus lane must give way to all the other road users resulting in long queues of buses.
