中小货运企业"生死劫"

"私人真是养不起货车了."不少从事货运的个体车主向记者诉苦.目前,随着油价上涨和治理超限超载,有个体车主甚至语出惊人--"搞个体货运,不超载就赔钱!"真相确实如此吗?记者就此对江苏货运市场展开采访.     

公路超载"顽疾"为何屡治不愈?

近几年来,我国公路运输车辆超载现象愈演愈烈,给公路基础设施和交通安全造成极大危害.超载"顽疾"为何屡治不愈?     

"治超"--一曲回荡在中国大地上的"四面楚歌"

2004年6月20日9时,在全国治超工作领导小组和各地政府统一部署下,各级交通、公安等部门协同配合,全国约有20万名执法人员进入执法岗位,全面展开治理车辆超限超载的统一行动.这一阶段对超限超载车辆进行集中治理的措施主要有四项:一是清理"大吨小标"车辆,恢复标准吨位.二是整顿车辆非法改装企业.三是集中开展路面治理工作.四是降低运输成本,调节利益关系.我国力争用一年时间,使车辆超限超载、"大吨小标"和非法改装车辆问题得到有效遏制:用三年时间从根本上解决超限超载问题.

高速公路超载问题的分析治理

介绍了高速公路车辆超载问题,概括了车辆超载的原因,分析了高速公路超载的危害,提出了综合治理超载的方法.     

基于"互联网+"新形势下治超体系的建立

近年来,随着我国社会经济和道路运输飞速发展,公路货运车辆超限超载运输问题也日渐突出,公路货运超限超载已成为危害公路交通可持续发展的"痼疾"。随着科学技术的发展,治超工作增添了很多新手段、新方法,"互联网+"正在改变传统的业务管理模式。本文通过从问题导向出发,从顶层设计入手,建立多部门、跨区域联合的综合治理、系统治理的长效机制。     

公路"治超"与执法成本

加大路面检查力度,对超载车辆处以重罚,是一个办法,但却不是治本之策.而且,我们出台一项执法举措,也不能不考虑执法成本,不能不考虑执法成本与执法效果之间的关系.     

对"治超"工作的几点思考

近几年,各部门重拳出击,采取查处超员和超限、超载车辆,计重收费、重核车辆出厂技术参数等举措,对搞好道路交通安全,避免公路恶性损坏起了很大作用。但是也应该看到,"治超"在带来积极效果的同时,也带来一些"负面"效应,值得我们认真总结思考。     

车辆超限超载的成本-收益分析

文章从成本-收益的角度对车辆运输进行了全面的分析,探讨超限超载现象发生的原因,并提出治理超限超载的对策,关键是将超限超载的外部成本内部化,使车辆运输的平均成本在超限超载之后迅速上升,从而消除超限超载的利润空间。当前治理超限超载的首要工作是在车辆的生产、改装、营运和监管环节加强治理,降低运力供给和提高货运价格,使货运市场摆脱"不超不赚"的怪圈。

Factors influencing the propensity to cycle to work

This paper describes the development of a mode choice model for the journey to work with special emphasis on the propensity to cycle. The model combines Revealed Preference (RP) and Stated Preference (SP) data to form a very large and comprehensive model. RP data from the National Travel Survey was combined with a specially commissioned RP survey. A number of SP surveys were also undertaken to examine the effects of different types of en-route and trip end cycle facilities and financial measures to encourage cycling.The development of the model is described in detail. The model was used to forecast trends in urban commuting shares over time and to predict the impacts of different measures to encourage cycling. Of the en-route cycle facilities, a completely segregated cycleway was forecast to have the greatest impact, but even the unfeasible scenario of universal provision of such facilities would only result in a 55% increase in cycling and a slight reduction in car commuting. Payments for cycling to work were found to be highly effective with a £2 daily payment almost doubling the level of cycling. The most effective policy would combine improvements in en-route facilities, a daily payment to cycle to work and comprehensive trip end facilities and this would also have a significant impact on car commuting.     

将弯管敷设变更为弹性敷设的情况分析

根据输油工况和管线沿途的地质、土壤等状况,广泛采用管材多极变壁厚进行管线敷设,管线敷设还尽可能采用弹性敷设和冷弯弯管敷设,以便减少固定墩的数量。为保证焊接质量和管材强度,在管线上允许加装30°、45°、60°曲率半径大于5DN的3种热煨弯头与冷弯管（曲率半径=40DN）相配合,以适应管线走向所需要的转角。文中分析了3种敷设,选出最佳的敷设方案以降低成本。     

Beyond the journey to work

This paper analyses the Nationwide Personal Transportation Study (NPTS) surveys of 1977 and 1983–1984 that reveal a remarkable increase in nonwork travel. This growth occurred among all city size classes but was stronger for suburban residents. Also interesting is that the rate of increase in nonwork trips was higher in the peaks (especially in the morning peak) than in the off-peak period. Some, but not all, of these trips may be price-elastic and might be diverted by congestion pricing strategies. The nonwork trip growth is concentrated in the “family and personal” and the “social and recreational” categories. Although higher-income households make more trips than low-income households, the increase in nonwork travel is common to all income groups. The growth in nonwork travel does not appear to be closely associated with the growth in female employment or trips related to the children of working women. The most convincing explanation of the growth in nonwork travel is that the trip cost savings (less time and distance) experienced because of more efficient spatial settlement patterns have provided an incentive to undertake more trips. Another implication is that urban economic models and urban transport policies have overemphasized the journey to work, especially to the central business district (CBD).

如何提高汽车耐用性

走合期合理使用 首先,购进新车后,一定要根据新车走合期的特点来合理使用.新车走合期有什么特点呢?第一,机件磨损快.汽车出厂前虽然按规定进行了磨合处理,但机件表面仍然较粗糙,加之新零配件间有较多的金属粒脱落,使磨损加剧.第二,故障多.
