【摘要】:在我國,混合交通流是城市交通的特色,在今后的很長一段時間,這一局面仍將持續(xù)下去。信號燈的設(shè)置能有效地從時間上分離各交通流,減少沖突點。然而,右轉(zhuǎn)機動車通常不受信號燈的控制,與行人的沖突不可避免。如何有效地解決右轉(zhuǎn)機動車與行人的沖突,是本文所要探討的問題,這既是緩解交叉口擁堵,改善道路運行效率的要求,也是以人為本理念的體現(xiàn)。論文首先對人車沖突相關(guān)概念進行定義,提出以“群”為單位研究行人的交通特性,將沖突點的定義延伸為沖突區(qū)域,更好地反映人車沖突特性。采用視頻法對選擇的典型交叉口進行調(diào)查,基于調(diào)查數(shù)據(jù)對行人和右轉(zhuǎn)車交通特性進行分析,包括行人群的到達和速度分布,右轉(zhuǎn)車的車頭時距和速度分布,并分析沖突對兩者交通特性的影響規(guī)律。基于交通沖突技術(shù),突破以往研究中采用單一指標(biāo)交通沖突率的局限,考慮行人空間需求,選取空間安全度和交通沖突率兩個指標(biāo),分析這兩指標(biāo)的有效性及指標(biāo)值的計算方法。分析并改進經(jīng)典的白化值函數(shù),采用改進的灰色聚類法對右轉(zhuǎn)機動車與行人沖突區(qū)域的安全性進行評價,確定各區(qū)域的安全等級。提出行人與右轉(zhuǎn)車沖突系統(tǒng)人均延誤模型,將與行人沖突的兩股右轉(zhuǎn)車流分為均不受控、單股受控和兩股受控,分析這三種情況下人均延誤的變化情況。針對典型四相位十字交叉口,在不同行人與右轉(zhuǎn)車流量下計算三種情形的人均延誤得到右轉(zhuǎn)相位設(shè)置的臨界流量曲線。給出右轉(zhuǎn)專用相位具體設(shè)置方法,并結(jié)合實例對設(shè)置效果進行評價。
[Abstract]:In our country, mixed traffic flow is the characteristic of urban traffic, and this situation will continue for a long time in the future. The setting of signal light can effectively separate traffic flow from time and reduce conflict point. The right-turn vehicle is usually not controlled by the signal lights, and conflicts with pedestrians are inevitable. How to effectively solve the conflict between right-turn vehicles and pedestrians is the problem to be discussed in this paper, which is not only to alleviate traffic congestion at intersections. The requirement of improving the efficiency of road operation is also the embodiment of the people-oriented concept. Firstly, this paper defines the concepts related to the conflict between people and vehicles, and proposes to study the traffic characteristics of pedestrians with "group" as the unit. The definition of conflict point is extended to conflict area to better reflect the conflict characteristics of people and vehicles. The video method is used to investigate the typical intersection selected. Based on the survey data, the traffic characteristics of pedestrians and right-hand interchanges are analyzed. It includes the arrival and speed distribution of the people, the time distance and velocity distribution of the right turn, and analyzes the impact of conflict on the traffic characteristics of the two, based on traffic conflict technology. Break through the limitation of traffic conflict rate of single index in previous research, consider pedestrian space demand, select two indexes of space safety and traffic conflict rate. The validity of the two indexes and the calculation method of the index value are analyzed. The classical whitening value function is analyzed and improved. The improved grey clustering method is used to evaluate the safety of right-turn vehicle and pedestrian conflict area. To determine the security level of each region. Proposed pedestrian and right-hand conflict system per capita delay model, and the pedestrian conflict of the two right-turn flow is divided into uncontrolled, single-share controlled and two-share control. The variation of per capita delay in these three cases is analyzed. The critical flow curve of the right turn phase setting is obtained by calculating the per capita delay in three cases under different pedestrian and right turn traffic flow. The specific setting method of the right turn specific phase is given, and the effect of the setting is evaluated with an example.
