北京城市交通发展水平与宏观路网运行状态关系模型

在对北京城市交通发展水平统计分析的基础上,提出了城市交通发展水平指标选取的原则,从社会发展、交通供给和交通需求3个方面构建了由16个指标组成的城市交通发展水平综合评价指标体系,并提出了基于路网拥堵指数和骨干网高峰小时运行速度的宏观路网运行状态评价指标体系。通过对2003—2010年北京市实际数据的搜集和指标处理,确定了关系模型的输入指标,利用偏最小二乘方法建立城市交通发展水平与路网运行状态关系模型,并利用现有数据对模型进行验证,验证结果表明:模型精度在10%以内,能较好地满足实际应用需求。关系模型能为北京市未来城市交通发展决策和交通发展战略提供重要支撑。

甘肃省城市交通发展水平聚类分析

选取客运量、货运量、民用汽车拥有量等6项指标,运用SPSS软件对甘肃省14个市州的交通发展水平进行聚类分析。结果表明:甘肃省14个市州的交通发展水平有显著差异且可分为三大类,第一类包括武威市、酒泉市,第二类包括兰州市、嘉峪关市,其余10个市州为第三类。

河南省城市交通发展水平的聚类分析

城市交通发展水平与城市的规模相关,城市交通基础设施及服务系统对城市的发展有重要的作用。本文论述了河南省交通发展现状及城市在交通发展过程中出现的一些问题并找出影响交通发展的因素。然后,通过查阅资料来搜集河南省各主要城市的交通发展数据,用SPSS软件将有关样本城市的交通数据进行K-聚类分析。最后,针对有关结果提出了有利于城市交通发展的对策。

Development of City Transport System and Two-wheel Vehicles

Based on the study on the city transport systems of some typical cities worldwide,this paper put forward that each city transport system has its own development mode,which is influenced by the city development plan,economic development level,traveling vehicle composition etc..When some problems occur,such as the congestions caused by contradiction between the road capacity and vehicle composition,the city transport system may come into temporary maturity period.If the improvement for road system is limited meanwhile,optimized structure of vehicle composition should be an effective solution in this case.With the development of economy-internationalization,the development speed of city transport modernization is rapid.When traveling easiness is conflicting with efficiency,the advantages of public transport system become more obvious.Correspondingly,the superiority of two-wheel vehicles will reappear.Though the important function of two-wheel vehicles for alleviating city traffic problems is obvious,however,their development strategy must be reasonably proposed,and operation regulations must be performed accordingly.
