The paper presents the Vehicle-to-Infrastructure communication link used in Bucharest Traffic Management System. The local wireless communications are used to implement local signal priority for Public Transport Vehicles and for Emergency Vehicles and also are used as a back-up link Public Transport Management System. The primary communication link used for communication with vehicles in Public transport Management System is assured by a TETRA system. The paper is focused only on local wireless link that is based on IEEE 802.11g standard. A study for this communication link is under progress in junctions across Bucharest to determine several functioning parameters like: association time, maximum link distance, throughput, interferences, and also security issues related to this communication technology. The paper will present the study results and the conclusions regarding the use of WiFi technology as a reliable and secure vehicle-to-infrastructure link in Bucharest Traffic Management System.
