In Turkey, road traffic has been increasing rapidly in province centers with the increase of the number of vehicles. The number of motor vehicles has shown an increase of 70 % within the last decade in Turkey. Inner-city traffic control is regulated by traffic lights and traffic control units. Electronic control systems have been developed to enable the control of the largest area by using the least human resource throughout all time periods. Electronic control systems and their areas of use are discussed in this study. The characteristics and advantages of electronic control systems are presented. The present speed warning systems on Ankara-Eskişehir highway and the speed lane system in Konya province are examined. The system was set up at 5 points as 10 speed lanes round in both ways. The ten lanes with lengths ranging from 1000 meters to 3500 meters were selected from areas where accidents intensified due to high speed and where the traffic did not stop considering the last three years. The communication of the lanes was maintained through fiber optic cable network and wireless network infrastructure. The entire road was monitored by using 2 license plate reading cameras for the three lanes. The detection of the number of vehicles that pass through the zones with respect to time, the speeds of all the vehicles, and the detection of the wanted vehicles (stolen, seized, restrained) is possible through the system. The numbers of speed violations before and after the installation of the system was examined. It was seen that speed violations decreased from around 90% to around 1% considering the number of the passing vehicles. The decrease in speed violations was found to be parallel to the decrease in accidents. As the result of the assessment of the traffic regulation information in addition to traffic control enabled the solution of a large number of security-related cases.
