【摘要】：我國通道型高速公路多為雙向六車道及以上的多車道高速公路,其運行方式較為靈活,可在左側(cè)車道限制貨車通行。這種運行方式在降低客貨車混合程度的同時,導(dǎo)致貨車集中在右側(cè)車道,對換道車輛形成屏障,易產(chǎn)生沖突。在分流區(qū),存在大量強制性換道,貨車屏障效應(yīng)較為明顯,研究多車道高速公路運行方式對分流區(qū)交通安全的影響,具有重要意義。論文界定了運行方式的基本概念,統(tǒng)計車道限制策略下某高速公路的交通量、車頭時距和速度,分析交通流特征。基于數(shù)據(jù)流分析技術(shù),采用在線聚類和離線聚類雙層框架,對貨車屏障進(jìn)行識別。研究了分流區(qū)的幾何特征、運行特征和性能指標(biāo)。明確了分流區(qū)和分流影響區(qū)的范圍,將分流區(qū)在長度上劃分為預(yù)告、準(zhǔn)備、實施、恢復(fù)四個階段,分析了分流區(qū)寬度對交通運行的影響。根據(jù)強制性換道的最低次數(shù)及換道性質(zhì),劃分了分流區(qū)的四種基本構(gòu)型,并由此組合形成3種常見的多重分流區(qū)。提出以一定分流數(shù)量下,直行最大交通量作為分流區(qū)通行能力,并基于間隙-接受理論進(jìn)行計算。同時以密度作為分流區(qū)服務(wù)水平判別標(biāo)準(zhǔn),劃分了順暢、搶道、延誤、中斷四種分流形態(tài)。觀測了某高速公路上的分流行為,建立并統(tǒng)計了分流強度、分流長度、分流速度等描述分流難易程度的性能指標(biāo)。從宏觀和微觀兩個層次建立分流區(qū)交通流模型。歸納了交通流相變特征,以及交通流的流體力學(xué)模型和動力學(xué)模型,研究了分流區(qū)交通流的動力機(jī)制、混沌現(xiàn)象和穩(wěn)定性。分析了不同運行方式下交通流建模特征。闡述了駕駛行為的動力機(jī)制、影響因素和層次結(jié)構(gòu),把駕駛行為模型分為行為主義、符號主義和聯(lián)結(jié)主式三類模式。以強制性換道作為分流區(qū)的主要行為特征,基于有限理性準(zhǔn)則和前景理論建立模型,利用元胞自動機(jī)對模型進(jìn)行仿真驗證。分析了車道限制策略對小車換道行為的影響。采用交通沖突技術(shù)對分流區(qū)的交通安全進(jìn)行評價。分析了分流區(qū)交通沖突形成機(jī)理及特征。綜合交通沖突的潛在性、嚴(yán)重性、持續(xù)性、動態(tài)性和有限性,提出指標(biāo)需求,建立基于動量的瞬時沖突、累積沖突、平均沖突和統(tǒng)計沖突等四項指標(biāo)。為校驗?zāi)Ｐ偷臏?zhǔn)確性,制定交通沖突的觀測、統(tǒng)計和修正方法。引入換道階段模型和Newell跟馳模型,計算換道過程中的交通沖突,標(biāo)定了模型參數(shù)。分別基于回歸分析、神經(jīng)網(wǎng)絡(luò)和分形理論,集成交通沖突和交通穩(wěn)定性等其他交通安全評價指標(biāo)。提出不同運行方式下分流區(qū)交通沖突仿真方案。從運行方式選擇、上游限速和長度設(shè)置等三方面建立分流區(qū)交通安全對策體系。構(gòu)造了運行方式選擇流程,參照Wardorp平衡原理,預(yù)測交通流在車道上的分布,標(biāo)定交通流參數(shù)。分別基于效用函數(shù)和區(qū)間概率,建立運行方式選擇的決策模型�？紤]到交通運行的不確定性,運用模糊推理,制定分流區(qū)上游限速策略。運用回旋曲線擬合車輛換道軌跡,進(jìn)而采用重復(fù)博弈理論建立連續(xù)多次換道的軌跡模型,計算分流區(qū)合理長度。
[Abstract]:The channel type Expressway in our country is mostly two-way six lane and above multi Lane freeway. Its operation mode is more flexible. It can restrict the freight traffic in the left lane. This operation mode can reduce the mixing degree of the passenger and freight car, and cause the freight car to concentrate on the right lane and form a barrier to the change vehicle. The effect of freight car barrier is more obvious in a large number of compulsory lane changing. It is of great significance to study the influence of multi lane highway operation mode on the traffic safety of the distributary area. This paper defines the basic concept of the operation mode, statistics the traffic volume, the distance and speed of the headway under the lane restriction strategy, and analyses the characteristics of the traffic flow. According to the flow analysis technology, the on-line clustering and off-line clustering double layer frame is adopted to identify the freight car barrier. The geometric features, the running characteristics and the performance indexes of the distributary area are studied. The range of the distributary area and the distributary influence area is clearly defined. The distributary area is divided into four stages, such as the forecast, the quasi preparation, the implementation and the recovery, and the width of the distributary area is analyzed. According to the minimum times and changing properties of the mandatory lane change, the four basic configurations of the distributary area are divided and 3 common multiple distributary areas are formed, and the maximum traffic capacity under a certain distributary number is proposed as the capacity of the distributary area, and the calculation is based on the gap acceptance theory. As a criterion for the service level of the distributary area, the density is divided into four kinds of distributary forms, such as smooth, rush, delay and interruption. The distributary behavior on a highway is observed, and the performance index of the diffluence intensity, the length of the distributary and the velocity of the shunt, etc., are established and counted. The traffic flow in the distributary area is established from the macro and micro two levels. The characteristics of the traffic flow phase change, the hydrodynamic model and the dynamic model of the traffic flow are summed up. The dynamic mechanism, the chaos and the stability of the traffic flow in the distributary area are studied. The characteristics of the traffic flow modeling under different operating modes are analyzed. The dynamic mechanism, the influence factors and the hierarchy structure of the driving behavior are expounded, and the driving behavior model is described. It is divided into three types: behaviorism, symbolism and joint main type. It takes the mandatory change as the main behavior feature of the distributary area, establishes the model based on the finite rational criterion and the foreground theory, and uses the cellular automata to simulate the model. The influence of lane restriction strategy on the change of the lane change is analyzed. The traffic conflict technology is adopted. The traffic safety of the distributary area is evaluated. The formation mechanism and characteristics of the traffic conflict in the distributary area are analyzed. The potential, severity, continuity, dynamics and finiteness of the comprehensive traffic conflict are put forward, and four indexes, such as instantaneous conflict, cumulative conflict, average rush and statistical conflict, are set up, and the accuracy of the model is verified. To formulate the traffic conflict observation, statistics and correction methods, introduce the change stage model and the Newell following model, calculate the traffic conflict in the change process, and demarcate the model parameters. Based on the regression analysis, the neural network and the fractal theory, the other traffic safety evaluation indexes such as the traffic conflict and the traffic stability are integrated, and the different transportation is put forward. The traffic conflict simulation scheme in the distributary area is established. From three aspects, the operation mode selection, the upstream speed limit and the length setting, the traffic safety countermeasures system is set up. The operation mode selection process is constructed. According to the Wardorp equilibrium principle, the distribution of traffic flow on the lane is predicted and the traffic flow parameters are determined. The utility function and the interval are based on the utility function and the interval respectively. The decision model of the choice of operation mode is established. Taking into account the uncertainty of traffic operation, using fuzzy reasoning, the speed limit strategy is formulated in the upstream of the distributary area. The trajectory of the vehicle is fitted by the cyclotron curve, and the repeated game theory is used to establish the trajectory model of the continuous multiple channels, and the reasonable length of the distributary area is calculated.
