在经济欠发达地区发展航空运输,飞机和机场的小型化是节省建设投资、减少运营亏损的重要措施。应借鉴国外的成功经验,积极鼓励和支持通用航空企业兼营短途客货运输,此举既有利于完善综合交通运输体系,也有利于通用航空的发展。为推进通用航空企业参与短途航空客货运输,要抓紧制定颁布使用小型飞机从事航空运输经营活动的规则,以及小型支线机场的建设标准。 相似文献

随着机场开发和区域经济的一体化发展,以机场为基础的航空都市区规划建设成为发展趋势,作为临空新城,其交通规划具有特殊性。郑州航空港经济综合实验区(简称"航空港实验区")是全国首个上升为国家战略的航空港经济发展先行区,正处于全面深化改革、转变发展方式的攻坚期;现代、高效、便捷的综合运输体系是实现经济社会可持续发展的重要保障。本文借用SWOT模型的分析思路,深入分析航空港实验区综合交通发展的内、外部环境,借鉴国内外先进经验,提出航空港实验区2020年及2040年的发展目标、发展战略,为航空港实验区未来一个时期的综合交通运输发展指明方向,也为我国其他地区航空都市区综合交通运输体系的建设提供借鉴。 相似文献

"超限超载"的产生与发展,蕴藏着深层的内在运作机理,包含着复杂的经济社会原因.其中道路货物运输价格体系的长期扭曲失衡与成本结构的有欠合理是一个不容忽视的根本原因.为此,公路所开展了货运市场运价与成本"治超"专项研究,先后历时一个多月,行程数千公里,深入7省市运输一线,对21家典型企业和个体业户的23辆货车、24条线路进行了跟踪调查,获取了大量的第一手资料与原始数据,并对此进行了解析. 相似文献

Zambia has attempted to reduce her excessive transport dependency on her traditional transport routes via South Africa and the former Portugese colonies. The costly construction of the Tanzania‐Zambia Railway (TAZARA) was part of this diversification strategy. This article examines the nature, extent and direction of Zambian traffic, including its historical evolution. It explores further the place of TAZARA among the various routes to Mozambican, Angolan and South African ports, and the ensuing actual and potential competition. Future traffic patterns will be influenced not only by the direct and service‐oriented costs of the different lines, but also by the region's volatile and uncertain political climate. 相似文献

An examination of current population statistics shows that in the U.S. more than half of the population is without immediate access to a car, and in the U.K. more than three-fifths of the population is without access to a car. This phenomenon has been accentuated by national investment in both countries in major highway programs. The term carless refers to more than just households that own no cars. It extends, in households with cars to those without licenses (old and young), the handicapped, and even the licensed drivers who have no access to the family car when it is in use elsewhere (e.g. at work). The most severely effected are those in urban areas and especially the urban poor. Transportation expenses are limited for the poor when other family expenditures (food, shelter) take a high priority. Once the work trip has been satisfied, money for other trips, for the poor, is not always available. One solution to cost-free travel is pedestrianism (walking), but this too is difficult in urban areas where the pedestrian has been overlooked in favor of the car. Solutions to problems of the carless include dial-a-ride, better public transit, and better design of urban form. 相似文献
