“…According to two recent reviews on RGSs [11,12], UTOSPF is a dynamic, deterministic, reactive and distributed RGS. Also, UTOSPF tries to decrease the time distance between occurring of an incident in the traffic network and considering it in further calculation of optimal routes, by using of partitioning the traffic network to some smaller areas.…”

Recently, the authors proposed a distributed dynamic route guidance system called UTOSPF (Urban Traffic Open Shortest Path First) based on Wireless Sensor Networks (WSNs) and Open Shortest Path First (OSPF) protocol. In UTOSPF, the routes will be found only based on Estimated StreetTravel Times (ESTTs) which will be needed to pass the streets and regardless of Waiting Times for Green Light (WTGLs) which drivers spend behind the red lights. In this paper, a simple method will be proposed to involve the WTGLs in calculation of optimal routes and its simulation results will be presented. Simulation results show that this method can improve the average speed of vehicles up to 66% as compared to random routes and up to 27% as compared to original UTOSPF, in the simulated scenarios.

Route guidance systems become indispensable for car drivers because of its great convenience. To be efficient, these systems require optimal selection of the routes according to the preferences of drivers. In this paper, a novel route guidance algorithm is proposed for vehicular networks (VANETS). It uses the MVDR beamforming technique which can enhance coverage and reduce radio interference in wireless networks. The proposed algorithm aims to optimize coverage and connectivity of drivers to public hotspots while ensuring a reasonable total traversed distance. Performance results show that our algorithm outperforms the route guidance system using omnidirectionnal antennas and the shortest path algorithm.Index Terms-route guidance system, MVDR beamforming, vehicular networks.

“…Also, there are two comparison and classification on route guidance systems based on general features of route guidance systems [4,6]. Both of these reviews proposed some classification for route guidance systems based on some technical aspects without introducing their architectures and communications and also comparing them to find out the future Permission to make digital or hard copies of all or part of this work for personal or classroom use is granted without fee provided that copies are not made or distributed for profit or commercial advantage and that copies bear this notice and the full citation on the first page.…”

The term intelligent transportation systems (ITS) is generally used to refer to infrastructure and services, as well as the planning, operation, and control methods to optimize transportation and to increase the safety of transportation. U.S. Department of Transportation categorized the ITS to eight main categories including travel and transportation management, public transportation operations, electronic toll payment, commercial vehicle operations, emergency management, advanced vehicle control and safety systems, information management and, maintenance and construction management. Route guidance systems are one of the main components of travel and transportation management. Although route guidance systems will play an important role in future transportation, few reviews have been presented on them. In this article, we are going to review the main architectures which have been proposed so far, compare them and categorize them based on their structures and communications. This could be useful to find out the future trend of this technology and work on next issues in the field.
