An optimization model for traffic light control in an urban network of intersections is derived. The based on store-and-forward analytic relations, which account the length queue waiting vehicles front intersection. complicated with probabilistic relations that formalize requirements maintaining short queues vehicles. Probabilistic inequalities apply to each intersection city network. Approxima...

For having better and up to date traffic information access, spatio-temporal GIS for transportation (TGIS-T) needs to interact with the intelligent transport systems (ITS). Advanced traffic management systems (ATMS) is one of the components of the ITS and predicts traffic congestion and provides real time traffic information and optimal control strategies for freeways and arterials. ATMS needs ...

The unsignaled intersection of Jalan H Djole – Pasar Lama in Bekasi City is a densely populated commercial area with high economic activity. lack facilities and infrastructure that causes traffic jams at the also raises potential for conflict. This study aims to analyze level service, type conflict, conflict complexity an intersection. field survey method obtains primary data on approach volume...

Looking ahead to the time when autonomous cars will be common, Dresner and Stone proposed a multiagent systemsbased intersection control protocol called Autonomous Intersection Management (AIM). They showed that by leveraging the capacities of autonomous vehicles it is possible to dramatically reduce the time wasted in traffic, and therefore also fuel consumption and air pollution. The proposed...

Micro-simulation models are rapidly gaining acceptance as promising tools to analyse and evaluate ITS and other traffic control and management measures. Capacity is a primary concept in most of traffic engineering studies, however micro-simulation models generally ignore this concept. There are significant numbers of studies on capacity analysis based on analytical approaches including Highway ...

We present novel online mechanisms for traffic intersection auctions in which users bid priority service. assume that at the front of their lane are requested to declare delay cost, i.e. value time, and serviced decreasing order declared cost. Since expected arrive dynamically intersections, static pricing approaches may fail estimate user waiting time accurately, lead non-strategyproof payment...

In recent past, significant efforts have been made to improve the scientific understanding of exhaust dispersion phenomenon in urban street canyons/intersection. The amount of turbulence generated by natural winds within the street canyon might be smaller than that of traffic induced turbulence. Therefore, the influence of traffic-induced turbulence on exhaust dispersion has to be quantified. I...

The Kansas Department of Transportation (KDOT) became interested in roundabouts in 1998 and started designing and building roundabouts on state highways in Kansas (KS). They sponsored three research projects to get before and after data at several Kansas roundabout locations. These studies are still on going at Kansas State University (KSU). Concurrently, the traffic engineer in the City of Man...

Left-turn lanes at nonsignaiized intersections on two-lane interurban roads reduce the number of traffic interferences and increase the level of service for the through traffic. These improved conditions result from the opportunity turning vehicles have to decelerate and wait in a separate lane for a suitable crossing gap. Decreasing the number of interferences to through traffic reduces the nu...
