Since the high rate of road accident fatalities which is about 22,000 people each year is one of the most important problems affecting the Iran's road transportation, Road Maintenance and Transportation Organization as the main industrial authority of road transportation affairs is working on renewal of transportation fleet and structure of roads and speed controlling in order to reduce the rate of accidents occurring in roads network. The traditional method of speed control in Iran is based on the Tachograph which records vehicle's speed, time of leaving, and stoppage in conventional mechanical processing. In this method, the drivers must submit the Tachograph paper to each road police station and the police officer will give ticket to driver if he violated the authorized speed rate. However, since the speed rate and time of leaving is taken from the mechanical component of vehicle (speedometer)and recorded on the paper, in addition to the possible mechanical errors, it makes the manipulation of results possible. The Information Technology Department of Road Maintenance and Transportation Organization arranged an offline pilot study for the first time in Iran on 90 buses in the 431 kilometer Tehran-Esfahan route via new technologies like USB memory and GPS in order to develop a solution for above mentioned problem. In this method, additional information about the bus's route including real-time speed, average speed, unauthorized stopping points, speed violations, deviations from the predetermined route direction, bus and driver specifications, etc. can be collected, which was not possible using the traditional method such as Tachograph. After implementation and collection of existing information about the buses travel routes and other marginal information, this information were entered into the GIS(Geographic Information System) of the organization. The GIS was developed on the context of roads and technical constructions near the roads in the scale of 1:250,000. The various analyses were made to improve and control the fleet deployment situation under the GIS environment. Comparisons of drivers speed violations and accident occurred nearby and also relationship between accident happening and unauthorized stoppage of buses along the route, improvement and correction of authorized time limits of buses for traveling, are some examples. Finally, this research helped to monitor and control speed of bus driver to decrease the numbers of fatalities from traffic accidents.
