Road traffic management is an ongoing challenge. Machine vision (image processing), RFID gates, aerial surveillance, and/or remote sensors technologies are usually used to reduce traffic management problems. However, their major drawbacks are installation difficulties, maintenance over the time, error handling, coverage and cost effectiveness. Thus, low-cost, flexible, easily maintainable and secure...
Road congestion has troubled hundreds of thousands of drivers for a long time. In recent years, an application named dynamic routing, in which vehicles reroute themselves around congested areas with road information received, is proposed to deal with traffic jam. Due to lack of trust for traffic information data in vehicular ad hoc networks (VANETs), malicious vehicles can easily disseminate false...

Currently most car drivers use static routing devices based on the shortest distance between start and end position. But the shortest route can differ from the shortest route in time. To compute alternative routes it is necessary to have good prediction models of expected congestions and a fast algorithm to compute the shortest path while being able to react to dynamic changes in the network caused...
In this paper, we introduce a new geographic routing scheme for urban vehicular environments called ??Dynamic Road Connectivity-based Routing?? (D-RCBR). The proposed approach exploits distributed information about road connectivity and vehicles distribution to optimize routing decisions. To ensure the packet delivery, D-RCBR defines a new concept of Road Connectivity that provides local topology...
