Study On Lane-changing Model In Urban Microscopic Traffic Simulation

With the rapid development of economy and society, the bottleneck restrict of the traffic infrastructures has been more and more obvious. This kind of restrict is incarnated not only at the daily extruding traffic jam problem, but also at the environment pollution brougnt by the traffic blocking and the traffic security hidden trouble which is also caused by it. So the Intelligent Transportation System, putting the advanced information dealing technic, the communication technic, the control technic, the computer and network technic to apply in the traditional traffic system, is being highly regarded by our government and the others day by day, and it has been a hotspot in the transportation, the vehicle engineering and the other researching domain. Correspondingly, the microscopic traffic simulation technic is becoming an important tool for designing, estimating and optimizing ITS items. As one of the two basic microscopic traffic models, the lane changing model is figured as so complex and difficult to be described in mathematics. One important factor that block the lane-changing model developing is the difficultly acquired microcosmic data. According to the modern microscopic traffic simulation, it is believed that lane changing is the driving speciality of a driver and a colligating action process according to the stimulations from the surrounding informations such as speed, space and so on. People adjust himself to achieve the driving target including the information judgement and the operations. To describe such a complex driving behavior, a lot of micro-vehicle cell information sustaining is needed. So this is the fundamental reason why lane changing model's development is relatively slow and immature. This dissertation has deeply researched the lane changing model under the impelling of the Traffic Parallel Simulation System researching item of Changchun Science and Technology Bureau. It is linked to the modeling theory and method of the driving synergetic behavior simulation of National Physical Science funds item. Here follows the main content of this dissertation: Chapter one is exordium. It mainly introduces the researching background, target, meaning, content and technic route of this dissertation. In chapter two, this dissertation analyses the driver`s behavior in the process of lane-changing. It analyses and sums up the key driving behavior shaping factors. By researching the four key elements relating tightly to the driver`s behavior in the process of lane-changing including driver, vehicle, road and surrounding, it seperately analyses the influences on the driver`s behavior in the process of lane changing. Based the knowledge of cognitive psychology, the driver's cognitive...
