Traffic congestion has been a worldwide problem in metropolitan areas all over the world. Toll-based traffic management is one of the most applicable solutions against freeway congestion. This research chooses two toll roads, the SR-167 HOT Lane and the SR-520 toll Bridge (i.e. Evergreen Point Bridge), as study sites for simulation testbed developments to evaluate the toll impact on freeway ope...

This paper presents the model and algorithms for traffic flow data monitoring and optimal traffic light control based on wireless sensor networks. Given the scenario that sensor nodes are sparsely deployed along the segments between signalized intersections, an analytical model is built using continuum traffic equation and develops the method to estimate traffic parameter with the scattered sen...

Freeways represent the best example of an unconstrained traffic flow system with high speed operations, limited access and egress opportunities and few factors to inhibit traffic flow. This road type can typically achieve the highest throughput of traffic per hour per lane across most metropolitan networks. As most regular limitations to free flow traffic conditions are removed from freeways, t...

The growing number of vehicles in Jordan has contributed to traffic congestion, particularly at roundabouts. Roundabouts deflect high volumes flow. To improve the performance roundabouts, it is necessary consider impact all components on conditions, especially delay, queue length, and level service (LOS), reduce congestion enhance efficiency sustainability, etc. This study aims (a) identify opt...

Abstract Traffic safety is the main support of transportation engineering. Otherwise, there no benefit to a facility that lacks safety. Despite that, most road engineers in developing countries ignore traffic their designs or adopt traditional methods suffer from data weakness. So an urgent need for surrogate measures more accurate methods. This paper offers assessment at signalized intersectio...

Connected Vehicles (CV) share information among themselves and with the infrastructure, which contains parameters such as location, speed, acceleration, heading, status of majority vehicle systems. This paper assesses an algorithm for emergency vehicles preemption, aims to prioritize through signalized intersections, while minimizing negative impacts on other vehicular traffic. The is based con...

Estimating critical gap is crucial for modelling pedestrian level of service at crossings. Critical becomes more challenging in signalized crossings because the proportion pedestrians seeking gaps during red usually unknown. Besides, willingness – or lack it to cross signal indication varies by and local characteristics, which makes acceptance even challenging. The main objective this study pro...
