摘要
为能对汽车控制系统进行有效的实地测试,从而设计开发了基于英国典型高速公路路段的交通模型。该模型提供了对英国高速公路交通流量模拟、路面状况模拟、交通规则模拟及路面用户的微观行为模拟。驾驶员模型包括道路汽车跟随模拟和汽车超车模拟。通过对本交通模型微观参数的优化,使所开发的交通模型能与实地测试数据相符合,从而能更真实地仿真实际高速公路的环境。基于该模型所开发出的具有图形用户界面的能为汽车控制系统的测试与评估提供有效的支持。
A traffic model with traffic flow, road user behavior and vehicle dynamic model was designed providing computer simulation of traffic flow on a typical section of motorway in the UK. First a brief description of the motorway network itself was given, along with a discussion of UK driving conventions. Following this, the principle of microscopic simulation and the representation of road users were discussed. Driver models for both car following and lane changing were developed. The microscopic parameters in the driver models were optimized to fit the simulation results with existing empirical data.A graphical user interface （GUI）-based simulation software package was developed based on the traffic model and provided support for testing and assessment of the vehicle control system.
