This article presents information on the average speed enforcement system technology used in a university campus on sections with speed limits which is determined to be effective for decreasing the speeding behavior of drivers during a certain period of time. Afterwards, a study is presented which puts forth driver characteristics and their opinions. At the end of the application, drivers are subject to surveys within the scope of, "driver's personal characteristics, driver behaviors known by themselves, opinions on the average speed enforcement in the campus and the speed limits as well as other enforcements". A sample group of 729 drivers who regularly enter-exit the campus are included in the study as a result of which 52.8% of the participants indicated that the speed limits enforced via average speed enforcement are low. It is thought that the speed limits are not considered as reasonable by the drivers and that these limits may be neglected frequently in the future. It should be kept in mind that the study area is a campus while adjusting the speed limits with regard to the respect of drivers towards speed limits. Because the speed limits should be such that they pose no risks for pedestrian/cyclist safety.
