H ighway congestion is a daily phenomenon in all large metropolitan areas and a source of frustration and anxiety for millions of commuters and truckers. Incidents—vehicle accidents and breakdowns that tie up highway traffic-are a major cause of urban highway congestion. Once a concern limited to downtown areas of major cities, congestion is now a metropolitan-wide problem in medium, as well as...
Quick and reliable estimation of traffic conditions is of critical importance for advanced traffic management systems, especially when heavy congestion occurs. This paper proposes a methodology to predict queue spillovers in city street networks with signalized intersections using data from loop detectors (counts and occupancy). The key idea of the developed methodology is that when spillovers ...
In 2003, the city of London implemented a congestion pricing policy in order to reduce traffic and raise revenues for transit improvements. The dramatic success of this system has led to widespread consideration of the adoption of such variable tolling, including road pricing, in dense urban cores around the world. While from many perspectives the broad implementation of such congestion pricing...
Transportation is an important component of supply chain competitiveness since it plays a major role in the inbound, inter-facility, and outbound logistics. In this context, assigning and scheduling vehicle routes is a crucial management problem. In this paper, a vehicle routing problem with dynamic travel times due to potential traffic congestion is considered. The approach developed introduce...
A sustainable transportation system has been defined as “one that satisfies current transport and mobility needs without compromising the ability of future generations to meet their own” (Black, 1997; Richardson, 1999). The success of sustainable transportation in urban regions depends on encouragement of non-motorized (pedestrian and cyclist) and sharedride transportation modes instead of car-...

It is postulated that lane-changing vehicles create voids in traffic streams, and that these voids reduce flow. This mechanism is described with a model that tracks lane changers precisely, as particles endowed with realistic mechanical properties. The model has four easy-to-measure parameters and reproduces without re-calibration two bottleneck phenomena previously thought to be unrelated: (i)...
A Vehicular Ad Hoc network (VANET) is an emerging technology among the scholars and vehicular industries in recent years. The wireless collision Avoidance (CA) system sends early message to drivers before they reach accident zone on the road. This paper proposed an analytical model for warning messages through collision avoidance (CA) system. Use the Dichotomized head way model, the Braking mod...
27 Shared autonomous vehicles (SAVs) could provide low-cost service to travelers and possibly 28 replace the need for personal vehicles. Previous studies found that each SAV could service 29 multiple travelers, thereby eliminating several personal vehicle trips. However, a major 30 limitation of previous studies is the reliance on custom software packages with unrealistic 31 congestion models, ...
For the problem of tracking vehicles on freeways using machine vision, existing systems work well in free-owing traac. Traac engineers, however, are more interested in monitoring freeways when there is congestion, and current systems break down for congested traac due to the problem of partial occlusion. We are developing a feature-based tracking approach for the task of tracking vehicles under...
