【摘要】：為了緩解和抑制日益嚴峻的交通擁堵難題,世界各城市的交通管理者和研究者提出了建立公共交通為導向的交通發(fā)展模式,建立快捷、高效的公共交通服務系統(tǒng)。快速公交(Bus Rapid Transit,簡稱BRT)系統(tǒng)作為一種高效、快捷、經(jīng)濟、安全的公共交通模式,已得到了廣泛的認可和快速的發(fā)展。而BRT信號優(yōu)先技術的應用進一步提升了BRT系統(tǒng)的運營效率。在道路資源有限的情況下,公交信號優(yōu)先控制作為公交優(yōu)先技術的重要控制手段之一,其策略可靠、方案合理、功能全面的優(yōu)先方法是提升BRT系統(tǒng)運營效率和服務水平的重要保障。本文通過查閱國內(nèi)外大量的相關文獻和研究成果,綜合利用交通工程學、智能控制、交通仿真技術、網(wǎng)絡優(yōu)化技術及計算機軟件工程等理論,結(jié)合BRT的運營特性和交通特性,對路中型BRT系統(tǒng)的信號優(yōu)先控制方法展開研究,針對路中型BRT系統(tǒng)存在的問題,提出具有創(chuàng)新性的信號優(yōu)先控制策略。首先,從我國大部分城市BRT系統(tǒng)運營特性及結(jié)構特點出發(fā),分析了造成BRT公交車輛延誤的關鍵變量。并綜合以往對BRT系統(tǒng)信號優(yōu)先控制的研究成果,與以往基于車頭時距的信號優(yōu)先策略研究不同,以往研究僅僅考慮了目標公交車輛的車頭時距與計劃發(fā)車間隔的關系,本論文提出的信號優(yōu)先策略同時考慮了同線路相鄰三輛BRT車輛之間的車頭時距,能夠更好的提高BRT車輛的均勻性,降低站臺乘客候車延誤。然后,通過對路中型BRT系統(tǒng)的運營數(shù)據(jù)分析發(fā)現(xiàn),當路中型BRT系統(tǒng)的站臺位于交叉口時,存在BRT車輛進出站排隊過長,導致多次停車和溢流現(xiàn)象。針對上述問題,本論文創(chuàng)新性地提出了基于車頭時距的公交信號優(yōu)先和信號優(yōu)先抑制相結(jié)合的控制策略。最后,根據(jù)提出的基于車頭時距的路中型BRT系統(tǒng)信號優(yōu)先控制策略,建立路中型BRT系統(tǒng)的信號優(yōu)先控制模型,設計信號優(yōu)先控制系統(tǒng)實現(xiàn)流程,并基于VISSIM仿真軟件、VB.Net計算機編程、MySQL數(shù)據(jù)庫等技術,以濟南市實際路網(wǎng)為測試案例,對建立的模型進行仿真驗證和敏感性分析,結(jié)果證明：該模型能夠在不增加交叉口整體延誤的前提下,能夠有效降低乘客候車延誤,改善交叉口處站臺溢流情況。本論文提出的基于車頭時距的信號優(yōu)先控制策略,可以提高BRT車輛到達下游站點的均勻性,有效降低乘客候車延誤；又創(chuàng)新性地將傳統(tǒng)信號優(yōu)先策略與信號優(yōu)先抑制策略相結(jié)合,既降低了BRT公交乘客的延誤,又有效縮短站臺排隊長度,減少了溢流現(xiàn)象,能夠為城市交通管理者和公交運營者進行公交調(diào)度和信號設計提供較好的理論和方法支撐。
[Abstract]:In order to alleviate and restrain the increasingly severe traffic congestion problem, traffic managers and researchers in cities around the world have proposed the establishment of a public transportation-oriented traffic development model to establish a fast and efficient public transport service system.As an efficient, fast, economical and safe mode of public transportation, bus Rapid transform (BRTT) system has been widely recognized and developed rapidly.The application of BRT signal priority technology further improves the operation efficiency of BRT system.Under the condition of limited road resources, bus signal priority control is one of the important control methods of bus priority technology. Its strategy is reliable and the scheme is reasonable.The functional priority method is an important guarantee to improve the efficiency and service level of BRT system.Through consulting a large number of relevant literature and research results at home and abroad, this paper synthetically utilizes the theories of traffic engineering, intelligent control, traffic simulation, network optimization and computer software engineering, and combines the operation characteristics and traffic characteristics of BRT.The signal priority control method of medium BRT system is studied, and an innovative signal priority control strategy is proposed to solve the problems existing in the medium BRT system.Firstly, based on the operational and structural characteristics of BRT system in most cities of China, the key variables causing delay of BRT bus are analyzed.Based on the previous research results of signal priority control in BRT system, different from the previous research on signal priority strategy based on head-distance, the previous research only considered the relationship between the headway of the target bus and the planned departure interval.The signal priority strategy proposed in this paper also takes into account the headway distance between three BRT vehicles adjacent to the same line, which can improve the uniformity of BRT vehicles and reduce the delay of platform passengers.Then, by analyzing the operation data of the medium BRT system, it is found that when the platform of the medium BRT system is located at the intersection, there is a long queue of BRT vehicles in and out of the system, which leads to the phenomenon of stopping and overflow many times.Aiming at the above problems, this paper proposes a new control strategy which combines bus signal priority and signal priority suppression based on head-distance.Finally, according to the proposed signal priority control strategy of road and medium BRT system based on head-distance, the signal priority control model of road and medium BRT system is established, and the realization flow of signal priority control system is designed.Based on the VISSIM simulation software VB.Net computer programming and VISSIM database technology, taking the actual road network in Jinan as a test case, the simulation verification and sensitivity analysis of the established model are carried out.The results show that the model can effectively reduce the passenger delay and improve the platform overflow at the intersection without increasing the overall delay at the intersection.In this paper, the signal priority control strategy based on head-distance is proposed, which can improve the uniformity of BRT vehicles to the downstream stations, and effectively reduce the delay of passengers waiting.The traditional signal priority strategy and signal priority suppression strategy are innovatively combined, which not only reduces the delay of BRT bus passengers, but also effectively shortens the queue length of the platform and reduces the overflow phenomenon.It can provide better theory and method support for urban traffic manager and bus operator to carry out bus dispatch and signal design.
