Route Guidance System Based on OSPF Protocol
Route Guidance System (RGS) is a representative part of Intelligent Transportation System (ITS). The objective of this paper is to propose a framework of RGS based on Open Shortest Path First (OSPF) protocol, a widely used Internet routing protocol nowadays. RGS based on OSPF is composed of two parts: traffic network and guidance-data network. Guidance-data network includes Intersection Guidance Equipment (IGE) with Wireless Access Unit (WAU) and data links between IGEs. Each IGE calculates the shortest paths to every other intersection according to real-time link information exchanged between IGEs through flooding process. A vehicle can acquire route guidance from the nearest IGE found by In-vehicle Guidance Unit (IGU) by communicating with WAU through IEEE 802.11 Wireless Local Area Network (WLAN) protocol. The results indicate that the proposed system has the characteristics of rapid convergence, high reliability, good expandability and relatively low cost. This paper would provide a new insight into the research of traffic route guidance system.
