夜间长途大客车减速带区段驾驶人操作行为特征

Operating behavior characteristics of long-distance bus drivers passing the deceleration zone on nighttime

采用实车道路试验方法,设计长距离大型客车上实时采集驾驶人操作行为试验方案,研究客车驾驶人夜间在自由流交通条件下通过单向连续下坡减速带路段的操作行为特征。建立车速、加速度、油门和制动踏板行程及变化率等操作行为指标体系,研究进出减速带段驾驶人操作行为的变化。研究结果表明:在长下坡减速带初始阶段,油门踏板行程指标均小于无减速带阶段,并伴随偶有制动行为;平均车速、制动踏板行程为0分布频数与减速带路段成线性递减关系,减速带能够影响长下坡时驾驶人的操作行为,进而实现对车辆的控速。

This paper adopted the real vehicle road experimental method to study the characteris- tics of bus drivers＇ operation behavior under condition of free flow of traffic when he is passing through one-way continuous slope road at night. Building the evaluation index system of speed, aceelaration, throttle pedal and brake pedal stokes, and their changing rate, this paper studied the driver operating behavior changes in an out of deceleration zone. The results show that in the initial stage of long downhill speed bumps, the accelerator pedal stroke indexes are less than those of no-deceleration-zone phase, accompanied by the occasional braking behavior. Average speed, brake pedal stroke of 0 distribution freqtlency and speed bump section display a linear re- ducing relationship. Deceleration zone affects the pilot operation behavior to control the speed of vehicle during long downhill. 3 tabs, 12 figs, 12 refs.
