Research on Driving Behavior of Mountain City Passenger Car Drivers Based on GPS Data

摘要

In order to study the driving behavior characteristics of urban drivers in mountainous cities. In this paper, a modern data processing technology "GPS" has been used. Through GPS acquisition and comparative analysis method, the travel speed value of six passenger cars in Chongqing, which is collected in two days, is processed, and the effective acceleration value is filtered out. From the point of view of the proportion of sharp acceleration and acute deceleration in the driving process of the driver, the driving acceleration of six vehicle drivers is compared and classified, so the driver behavior characteristics are obtained. Then the driving speed of different drivers on the same road section is compared separately, and the behavior characteristics of different drivers for the same speed limit are summarized. The results show that: (1) The habits of different drivers in the driving process are not the same, the experiment out of three models, "Remain Constant", "Preference Acceleration", "Fast and Slow" type; (2) Because of its properties, in the process of driving, the speed range of passenger car is not large. That is, when driving the passenger car, different drivers will control the driving speed in a more stable range; (3) Different drivers treat so-called speed limit signs differently when crossing the same road, the experiment out of two types, "Complete Follow" and "Appropriate to Follow"; (4) Chongqing belongs to the mountain city, the large number of tunnels and bridges in passenger routes makes drivers more vigilant than other plain areas. In this paper, make a quantitative analysis of driver's driving behavior from the angle of GPS data, which is helpful for the management department to control and supervise the driving behavior such as driver speeding, and provides the basis for the improvement of road infrastructure.
