In: Transportmetrica B: Transport Dynamics. S.1-21. Mehr This paper studies traffic behaviour on one-way, two-way and two-way streets with prohibited left turns using three different methods; analytical formulations, static traffic assignment and microsimulation. While two-way networks result in shorter routes, one-way networks increase intersection throughput. Two-way networks without left Continua

In: Transportation Research Part C: Emerging Technologies, 77. S.257-274.  Mehr Recent years have seen a renewed interest in Variable Speed Limit (VSL) strategies, and their potential as a freeway metering mechanism or a homogenization scheme. This paper uses empirical data to examine both the macroscopic and microscopic effects Continua

In: Transportation Research Part C: Emerging Technologies, Volume 72, November 2016. S.109-129, ISSN 0968-090X. More This paper proposes an efficient signal control algorithm under the co-existence of conventional vehicles, connected vehicles and automated vehicles. Trajectories of the automated vehicles are modified to reduce delay and stops. Simulations show that both Continua

In: Journal of Advanced Transportation, 50 (4). S.406-420. PDF  More   An on-street parking maneuver often starts a temporary bottleneck, leading to additional delay endured by the following vehicles. If the maneuver occurs near a signalized intersection, the service rate of the intersection might be reduced. In this paper, a Continua

In: Transportation Research Part C: Emerging Technologies, 64. S.28-44. More The paper establishes the first real-time control algorithm for pre-signals. The algorithm combines multiple operation strategies at the intersection. It functions well with a wide range of input values and is robust to input errors. The real-time pre-signal minimizes person Continua
