To help mitigate road congestion caused by the unrelenting growth of traffic demand, many transit authorities have implemented managed lane policies. Managed lanes typically run parallel to a freeway’s standard, general-purpose (GP) lanes, but are restricted to certain types of vehicles. It was originally thought that managed lanes would improve the use of existing infrastructure through incent...

Traffic movement in a commuting scenario is a phenomena that results from individual and uncoordinated route choice by drivers. Every driver wishes to achieve reasonable travel times from his origin to his destination and, from a global point of view, it is desirable that the load gets distributed proportionally to the roads capacity on the network. This work presents a reinforcement learning a...

INTRODUCTION Traffi c circles have been a part of the U.S. transportation system since the early 1900s. However, traffi c circles faded away from the transportation scenario because of high accident and congestion rates due to the priority given to vehicles entering the intersection. It was not until the adoption of the “modern roundabout” in the United Kingdom during the 1950s that new meaning...

Incident-induced congestion is a major source of delay and frustration for drivers in large urban areas. Advanced Traveler Information Systems (ATIS) have been proposed within the framework of Intelligent Vehicle Highway Systems (IVHS) to address one component of the incident-induced congestion problem: diversion of drivers to alternate routes. To fully utilize the potential of ATIS, transporta...

We present a method for accurate aggregation of highway traffic information in vehicular ad hoc networks (VANETs). Highway congestion notification applications need to disseminate information about traffic conditions to distant vehicles. In dense traffic, aggregation is needed to allow a single frame to carry information about a large number of vehicles. Our technique, CASCADE (Clusterbased Acc...

In this paper we study the routing and rebalancing problem for a fleet of autonomous vehicles providing ondemand transportation within a congested urban road network (that is, a road network where traffic speed depends on vehicle density). We show that the congestion-free routing and rebalancing problem is NP-hard and provide a randomized algorithm which finds a low-congestion solution to the r...

The tremendous increase in motor vehicle usage during recent years in Indiana (7)* and in the United States (1) has greatly affected highway operation. This increase in motor vehicle usage has created an added demand on all components of the highway system resulting in increased operating costs to the motoring public. Inter­ sections are an important component of this system and the increased t...

Traffic congestion becoming the severe problem in most of the places of the world. From increased stress levels to serious national economical drawbacks and from time wastage to unrecoverable environmental issues. There are many traffic management and routing solutions have been researched ,developed and tested over and again , But still there are some areas that critically contribute to affect...
