城乡道路运输一体化的基本途径 总被引:3,自引:0,他引:3
在当前和今后的一段时期内,城乡交通发展的主要矛盾仍然是有限的交通供给与不断增长的交通需求之间的矛盾。为了缓解两者之间的矛盾,一方面要加强交通供给的能力,另一方面则要合理引导交通需求,城乡交通一体化从这两个方面出发,较好地满足了城乡交通发展的要求。因此,对城乡交通(主要表现为道路运输)一体化进行深入研究,处理好城乡交通发展中数量与质量、管理与效率之间的关系,对实现城乡交通跨越式发展大有裨益。一、城乡道路运输一体化的内涵及意义1、城乡道路运输一体化的内涵城乡道路运输一体化是逐渐优化城乡交通系统,方便居民出行和货… 相似文献

Pedestrians as compared to vehicular traffic enjoy a high degree freedom of movement even in heavily congested areas. Consequently, there are more alternative links available to pedestrians between a given origin‐destination (O‐D) pair. This paper describes a study done by the University of Calgary to evaluate the factors affecting the choice of route on intra‐CBD trips or trips within the Central Business District (CBD). An origin destination survey conducted in downtown Calgary, Alberta enabled the identification of the most significant factors influencing the choice. These factors were analyzed in relation to the physical characteristics of the location, personal characteristics of the trip maker and the type of the trip. It appears that most people chose the shortest link and factors such as the level of congestion, safety or visual attractions were only secondary. This suggests that the length should be made a major consideration when planning and designing pedestrian links. 相似文献

The main deficiency of most current modeling approaches to transportation can be identified as neglect of the integration of existing geographical knowledge in regard to the ex ante transport/land use modeling approaches, with its focus on territorial dynamics and theory development. This paper addresses this aspect of the problem by introducing a theoretical and methodological framework for the analysis of the interrelationship between land uses. The analysis attempts to determine to what extent the functional land use in a city can be considered an ordered pattern. The order sought does not rely on purely spatial configurations, but on the correlation of transportation and land use. The first section of this paper focuses on theoretical considerations. It stresses the fact that conventional approaches do not apply in the present context. It then suggests an alternative based on areas of influence and measured in terms of level of attractance of land uses. The second describes a procedure based on this alternative following the remarkable contribution of Hanjoul, Beguin and Thill. An application of this procedure to the analysis of Shanghai is then examined. Finally, an evaluation of the strategies for optimizing the interrelationship between land uses is presented. The paper concludes with a possible research agenda. 相似文献

The paper considers the possibility of quantitative analysis of behaviour, with particular reference to travel behaviour, from a methodological standpoint. The chief conclusion is that the nature of the subject implies that disaggregate statistical analysis is the most useful technique. The relationship of this methodology to theoretical issues is discussed, concluding that general theoretical issues are not susceptible to empirical resolution. The theoretical framework essential to analysis or forecasting of behaviour must therefore be established a priori The paper concludes with a discussion of the practical problems and achievements of disaggregate analysis. 相似文献

Reliability of travel modes was found to be the most important characteristic of transportation systems in several attitudinal investigations of individual travel behavior. This paper represents the first part of a research effort aimed at gaining a better understanding of the characteristics of reliability of transportation modes in urban travel. In this research, reliability characteristics are identified; their importance relative to each other is assessed, and an insight into possible structure of an objective reliability index is discussed. The research is based on perceived values of reliability, which were identified through a large attitudinal survey conducted in the Chicago metropolitan area. 相似文献
