In this paper, we propose a consensus algorithm with input constraints for traffic light signals in transit signal priority (TSP). TSP ensures control strategy of traffic light signals can be adjusted and applied according to the real-time traffic status, and provides priority for buses. We give the convergence conditions of the consensus algorithms with and without input constraints in TSP res...

This article tackles a pervasive problem in connected transportation networks: the issue of conflicting right-of-way between trams and Connected Vehicles (CV) at intersections. Trams are typically granted semi-exclusive right-of-way, leading to clash with CV. To resolve this challenge, study introduces Transit Signal Priority (TSP) system guidance framework that seeks minimize unintended delays...

Recent progress in technology has facilitated the design, testing, and deployment of traffic signal priority strategies for transit buses. However, a clear consensus has not emerged regarding the evaluation of these strategies. Each agency implementing these strategies can have differing goals, and there are often conflicting issues, needs, and concerns among the various stakeholders. This rese...

A queue jumper lane is a special bus preferential treatment that combines a short stretch of a special lane with a transit signal priority (TSP) to allow buses to bypass waiting queues of traffic and then to cut out in front of the queue by getting an early green signal. This paper first proposes a signal control design for queue jumper lanes with actuated TSP strategies and then compares its p...

The article discusses a strategy, referred to as Categorized Arrivals-based Phase Reoptimization at Intersections (CAPRI), which integrates transit signal priority and rail/emergency preemption within a dynamic programming-based real-time traffic adaptive signal control system. The system takes as input sensor data, from detectors, automatic vehicle locators, transponders, etc., for realtime pr...

Bus bunching is a severe problem that affects the service levels of public transport systems. Most previous studies in field Signal Priority (BSP) and Transit (TSP) focus on reducing bus delay at signalised intersections ignore importance balancing headways. However, since general BSP methods allocate uneven priorities for individual buses, headways sequences are prioritised or delayed randomly...

A multi-QoS scalable-distributed-arbitration (MSDA) ATM switch is described that supports both highand low-priority traffic under the head-of-line-priority discipline. It uses crosspoint and transit buffers, each consisting of a highand low-priority buffer. The buffers arbitrate in a distributed manner the selection of which cellsto transmit. The MSDA switch supports multiple QoS classes while ...
