Infrastructureless Inter-Vehicular Real-Time Route Guidance

This paper presents an inter-vehicular communication (IVC)-based algorithm for real-time route guidance in urban traffic networks. It is built on information sharing among some searcher vehicle and candidate vehicles traveling in the same direction, to the same destination and within a specific communication range. The paper discusses in details the algorithmic procedure and conditions for information sharing. A microscopic simulation model is utilized to assess the effectiveness of the algorithm against another benchmark algorithm; namely, centralized shortest path algorithm. Comparisons of the two algorithms´ average travel time, and overall network productivity are presented. The algorithms performances are captured for various scenarios reflecting network congestion levels, link speeds and link lengths.
