“…Other implementations suggested that the bus-only lane can be used by other vehicles whenever buses were not using the lane. The concept of intermittent bus lanes was proposed by Viegas et al and was demonstrated in Lisbon as a 6 month pilot project (13). Using data captured by loop detectors on every lane, the study found a 5%-20% increase in bus average speed and no significant impact on the general traffic.…”

“…The majority of the studies reported in the literature use simulation technologies to investigate the outcomes of managed lanes. Theoretical research does not capture all practical situations, therefore a real world application is necessary to act as a prototype (13). Real-life applications play a key role in assessing the impacts of potential initiatives and provide an opportunity for all stakeholders to give guided decisions about whether to move ahead with a full implementation, modify, or stop.…”

“…They could also demonstrate to the private sector that the public sector is proceeding carefully with the implementation of new ideas and applying only those that are successful (7). Prior studies, such as Viegas et al and Currie and Lai, have employed pilot tests, and investigated the intermittent use of bus-only lanes that allow all vehicles in the bus-only lane when it is not used (13,14). The main objective of the pilot test in Norwich, U.K., was to encourage environmentally friendly vehicles; therefore only clean vehicles were permitted in the bus lane.…”

With ongoing population growth and rapid development in cities, the demand for goods and services has seen a drastic increase. Consequently, transportation planners are searching for new ways to better manage the flow of traffic on existing facilities, and more efficiently utilize available and unused capacity. In this research, a lane management strategy that allows freight vehicles to use bus-only lanes is empirically evaluated in an urban setting. This paper presents an analysis of data that was collected to evaluate the operational impacts of the implementation of a freight and transit (FAT) lane, and to guide the development of future FAT lane projects by learning from the case study in Seattle, U.S. The video data was converted to vehicle counts, which were analyzed to understand the traffic impacts and used to construct a discrete choice model. The analysis shows that transit buses used the FAT lane 96% of the time, and authorizing trucks to use the lane did not affect that lane choice. Trucks used the FAT lane, but their utilization decreased with increasing numbers of buses in the FAT lane. Instead of higher rates of trucks, unauthorized vehicles, such as passenger cars and work vans, increasingly used the FAT lane during congestion. As a result of their differing schedule patterns, trucks and buses used the FAT lane at complementary times and trucks showed relatively low volumes in the FAT lane. Overall, the results are promising for a lane management strategy that may improve freight system performance without reducing transit service quality.

“…This concept strongly depends on the implementation of traffic signal priorities in order to clear downstream queues in front of the buses. Several field tests and permanent deployments have been conducted in Lisbon [23], Melbourne [24], Bologna [25], and Lyon [26]. There is a high variance in the results of similar projects, which can be explained by the differences in traffic conditions and volumes [27].…”

In mixed traffic, the popularity of public transport (PT) is still affected by relatively low operating speeds compared to private vehicles. To overcome this, PT priority measures have been proposed and adopted extensively. However, existing solutions such as exclusive bus lanes or traffic signal priorities are often limited in terms of available road space or large-scale feasibility. In this paper, we propose a Vehicle-to-Vehicle/Infrastructure (V2X)-based dynamic PT priority concept in mixed traffic called Virtual Right of Way (VROW). Private vehicles in front of a PT vehicle make spaces through collaborative lane changes within a dynamic clearing distance computed based on the current traffic situation. This allows a more efficient allocation of road space while still maintaining a high level of PT priority. In this paper, we evaluate the potential traffic impacts of VROW on both PT and private vehicles by conducting microscopic traffic simulations within a small urban network and a highway scenario. Comparisons with mixed traffic and other existing bus lane priority strategies, in terms of operation and safety concerns, are analyzed and highlighted. Simulation results show that VROW improves the PT operational performance with only a marginal influence on private vehicles measured by their average travel time and the number of lane changes.INDEX TERMS Dynamic bus lane, microscopic traffic simulation, traffic impact analysis, V2X.

“…When the bus leaves the section, it becomes a lane for regular traffic. Such operation scheme could work effectively when bus service frequency is low such that regular traffic will not suffer much delay, which has been analytically investigated by Viegas and Lu [15] and tested by some field experiments conducted in Lisbon, Portugal [16] and Melbourne, Australia [17]. In order to assess different transit priority measures, Zhu [18] proposed the cellular automata‐based approach to investigate different scenarios of the DBL, the IBL and ordinary lanes and found that the IBL strategy performs best in terms of the trade‐off between bus flows and regular traffic.…”
