Abstract:

As the key traffic protection zone, school zone has attracted attention of all circles. In order to improve the traffic safety of school zones, this paper focuses on the traffic safety facilities around primary schools in Beijing. A field investigation of road traffic condition and conflict between people and vehicles is conducted, aiming to classify the types of schools. Meanwhile, the demand for traffic safety facilities around primary schools base on different groups of traffic participants is obtained through a subjective questionnaire. Afterwards, a driving simulator experiment is performed to evaluate the effects of different programs with various traffic safety facilities. The differences in performances are discussed with three dependent variables including average speed, relative speed difference, standard deviation of acceleration. Finally, the optimal program is got for different types of schools. It provides a theoretical basis for the optimal setting program of traffic safety facilities for different school zone.
