Abstract
Motor vehicle inspection (MVI) services and exhaust gas emission measurement have gained great importance in recent years due to air pollution in big cities. Some of the urban air pollution in part results from exhaust gas emissions from motor vehicles, and therefore periodic inspections have been carried out by the private sector since privatization in 2005. The main purpose of mandatory vehicle inspections is to ensure road traffic safety, thereby preventing environmental damage, and reducing the number of vehicles that endanger life and property safety on the highway.
Periodic inspection of motor vehicles in Turkey, are carried out by the private sector at 269 vehicle inspection stations of which 189 are stationary and 80 are mobile. In addition, an appointment system is also implemented in some stations to prevent long waiting times. The operating company has greatly contributed to the vehicle traffic and road safety in Turkey, as well as to the prevention of air pollution via exhaust gas emission measurement services.
The aim of this study is to measure the performance of
the MVI station located in central Eskişehir using objective criteria and to
evaluate the appointment system in use. The main emphasis is on vehicle waiting
times and associated costs incurred at the station. At this vehicle inspection
station, only appointment vehicles are accepted and vehicle owners are expected
to make an appointment in advance. A discrete-event simulation model was
created using ARENA software, which recreates the vehicle inspection process on
the computer environment. Daily operations at the station were simulated for 30
days and performance indicators such as average utilization rates of resources,
average number of vehicles in lines, average waiting times of vehicles were
estimated by simulation. Various vehicle acceptance policies, queueing
configurations (e.g., using different number of parallel lines) were compared
and recommendations were offered to reduce average inspection time and improve
staff efficiency. These suggestions have significantly improved the service
capacity of the station and the average waiting times of the vehicles in
general.
