Abstract :

Average Speed Enforcement is a global new approach that is one of the speed enforcement systems applied to solve high speed and accident problems. This application measures the average speeds of vehicles over a section, thereby encouraging the drivers to obey the speed limit for longer distances. Accidents due to high speed occur within the borders of the Antalya Mediterranean University in Turkey. In this study, average speed technology was setup on mobile vehicles for a safer traffic occasion. Average speed values of drivers were measured in two period 1st of which is secret and 2nd of which is announced via 1^st and 2^nd period (before/after) speed etudes at 11 different sections with speed limits of 20, 30 and 50 km/s. Average speeds decreased along the 20, 30 and 50 km/s speed limit sections by 2.15 km/s (%4.50), 1.81 km/s (%5.10) and 4.50 km/s (%8.35) respectively as a result of the applied system without any enforcement sanction but only by way of warnings and announcements. A statistically significant difference at a level of p 0.05 was determined between 1^st period /2^nd period speed averages. It was determined at the end of the 2^nd period that the system is effective for decreasing the average speeds; however, it was also observed that the drivers on the F, G, A, H and J sections started straying away from the consistency to decrease their speeds. It was determined that the speed limit application started losing its effectiveness along these sections as we moved away from the announcement date since there was no enforcement sanction which had an adverse effect on the efficiency of the applied system.
