信号交叉口换相提示方式对驾驶员决策的影响分析

The Analysis about the Influence of Signal Intersection For Phase Change on the Driver's Decision

信号换相提示装置在我国许多城市的交叉口得到了应用,其中倒计时表最为常用。但国内对倒计时信号灯的作用和效果认识不一,对于这些装置对交叉口交通运行安全和效率的影响存在分歧。从驾驶员交通心理角度,对信号交叉口换相提示的影响进行了研究。通过问卷形式,分类调查安装倒计时装置的支持率和驾驶人在倒计时信号灯交叉口心理预期行为。研究结果表明,81.8%的汽车驾驶人支持设立信号倒计时装置;当红灯剩余时间超过31s时,关闭发动机可降低污染物排放,超过72s时,关闭发动机可降低燃油消耗。

Signal reversingpromptdevice has been applied to signalized intersections inmany cities in China, and countdownis most commonly used. However there was no traffic rules regulate these signal lights in China so that the application of these lights is disordered and results in lots of traffic accidents. At present theeffect of countdown in improving the intersection safety and efficiency have differences, and there are less research on intersections efficiency in our country about reversing prompt. This paper targets at typical intersections in Harbin, from thetraffic psychology of drivers to study the impact of reversingpromptdevice. In the matter of traffic psychology,through the questionnaire survey, surveying the support rate of co untdowndeviceinstallationandthepsychological possible behavior of driver in thecountdown signal intersection. Installation of thecountdownobviously reduces the video analysis results show that 81.8% of the car drivers support the establishment of signal countdown device; and if the alarm time is over 31 s, shut down the engine can reduce the pollutant emissions, and if the time id over 72 s, shut down the engine can reduce the fuel consumption.
