中文摘要：

分析了快速城市化地区中等城市的交通流时空分布特性,基于2008年东莞市区综合交通规划交通流量调查数据,研究了交通量车种构成、时间分布特性、空间分布特性及现状路网特征,采用TransCAD交通规划软件对路网交通负荷度进行了综合评价,分析了东莞市区现状交通问题,提出了具有针对性的交通发展策略。分析结果表明：该类城市小汽车出行比例高,公共交通发展滞后;交通基础设施严重不足;出入口客货混行及过境交通现象严重;路网结构不完善,道路功能不明确。提出了完善道路网络系统,优化城市交通结构,构建高效公共交通体系,规范交通管理,土地利用与交通协调发展等政策措施。

英文摘要：

In order to analyze the traffic flow space-time distribution characteristics of medium city in fast urbanization area,vehicle class composition,the temporal and spatial distribution characteristics of traffic flow,and road network characteristics were statistically studied based on the traffic flow survey data of comprehensive transportation planning for Dongguan in 2008.The traffic load of base road network was comprehensively evaluated by using traffic planning software TransCAD.The current traffic situation in Dongguan was anatomized.The traffic development strategies of medium city were put forward.Analysis result indicates that the trip proportion of car is very high,the development of public transportation lags behind,transport infrastructure has a serious shortage,the mixed running phenomenon of passenger-freight traffic and transit traffic is serious in access points,road network structure is defective,and road function is not clear in medium city.Traffic strategies are suggested,including improving road network system,optimizing the structure of urban traffic,building efficient public transport system,regulating traffic management,and coordinating transportation and land use.2 tabs,12 figs,10 refs.
