【摘要】：信號換相提示裝置在我國許多城市的交叉口得到了應(yīng)用,其中倒計時表最為常用。但國內(nèi)對倒計時信號燈的作用和效果認(rèn)識不一,對于這些裝置對交叉口交通運(yùn)行安全和效率的影響存在分歧。論文從交通心理、運(yùn)行效率、安全性等方面,對信號交叉口換相提示的影響進(jìn)行了研究。通過問卷調(diào)查,分類調(diào)查安裝倒計時裝置的支持率和駕駛?cè)嗽诘褂嫊r信號燈交叉口心理預(yù)期行為；基于視頻數(shù)據(jù),按照路面條件和交叉口相位控制方式,分類提取不同換相提示方式下駕駛?cè)藛臃磻?yīng)時間、車頭時距、黃燈期間交織區(qū)車輛滯留率和闖紅燈率等參數(shù),運(yùn)用SPSS中的T檢驗方法獲取運(yùn)行參數(shù),對倒計時信號的影響進(jìn)行顯著性分析,驗證倒計時表的有效性；應(yīng)用VISSIM仿真軟件,對不同換相提示方式下交通特性進(jìn)行仿真對比分析。研究結(jié)果表明,倒計時換相提示裝置顯著降低駕駛?cè)藛臃磻?yīng)時間,提前了車隊達(dá)到飽和車頭時距的時間,提高了交叉口的運(yùn)行效率；但增加了黃燈期間交織區(qū)車輛滯留率和闖紅燈率,對交叉口交通安全可能具有一定潛在的負(fù)面影響；仿真分析結(jié)果顯示,相較于閃爍信號燈,安裝倒計時信號燈的交叉口,車輛行程時間降低了11.63s、延誤時間降低了19.05%,排隊車輛長度降低了12.58m,可能通行能力提高了2310pcu/h；81.8%的汽車駕駛?cè)酥С衷O(shè)立信號倒計時裝置；當(dāng)紅燈剩余時間超過31s時,關(guān)閉發(fā)動機(jī)可降低污染物排放,超過72s時,關(guān)閉發(fā)動機(jī)可降低燃油消耗。
[Abstract]:Signal commutation device has been used in many intersections of cities in China, among which countdown time meter is the most commonly used. However, the function and effect of countdown signal lamp are different in our country. The influence of these devices on traffic safety and efficiency at intersections is different. This paper discusses traffic psychology, operation efficiency, safety and so on. The influence of commutative cues on signalized intersections is studied. By means of questionnaire survey, the support rate of countdown devices and the psychological expectation behavior of drivers at countdown signal intersections are investigated. Based on the video data, according to the road conditions and intersections phase control mode, the driver start reaction time and the headway time are extracted in different commutation mode. The parameters such as vehicle retention rate and red light running rate in the interlaced area during the yellow light period are obtained by using the T test method in SPSS. The significance of the influence of countdown signal is analyzed to verify the validity of the countdown table. The traffic characteristics under different commutation modes are simulated and analyzed by using VISSIM simulation software. The results show that the countdown commutative device can significantly reduce the driver's start-up reaction time. The time when the motorcade reaches the saturated front distance is advanced, and the running efficiency of the intersection is improved. However, it increases the vehicle retention rate and red light rate in the interlaced area during the yellow light period, which may have a certain potential negative impact on the traffic safety at the intersection. The simulation results show that the vehicle travel time is reduced by 11.63s and the delay time is reduced by 19.05% compared with the intersection where the flashing signal is installed and the countdown signal is installed. The queue length was reduced by 12.58m, and the possible capacity was increased by 2310pcu-h. 81.8% of vehicle drivers support the establishment of signal countdown devices; When the remaining time of red light exceeds 31s, the emission of pollutants can be reduced when the engine is closed, and the fuel consumption can be reduced when the engine is shut off for more than 72s.
