Abstract

Abstract: In order to improve the safety of road traffic under the aging background, based on a driving simulator, the car following behavior of older drivers and the influencing factors were investigated. Headway, speed and response time were selected as the indexes of car following behavior. Difference in the car following behavior between older and younger drivers was analyzed, and then Pearson correlation coefficient method was used to analyze the relationships among the car following behavior, drivers' age, work load and drivers' preference. The results show that compared with younger drivers, older drivers' time to responding to the emergency brake is longer, and they always adopt the larger headway and are more variable in their speed, and that the car following behavior is significantly related to drivers' age, work load and drivers' preference.

Key words: older drivers, driving simulation, car following behavior, difference analysis, correlation analysis
