本文是美国运输工程协会技术委员会4A-20准备的“发展中国家的交通工程实践”报告的摘要。很多发展中国家,随着他们的城市成为就业和贸易中心,机动车辆迅速增长。迅速发展的发展中国家,存在竞争国家所需的环境,但缺少发展道路设施的资源。因此,在发展中国家之间,在交通工程特性、规范和交通管理技术等方面均有很大的不同。为了总结鉴定各自的经验,以便适用于其他国家,尤其是发展中国家,美国成立了研究发
This is a summary of the “Traffic Engineering Practices in Developing Countries” report prepared by the American Society of Transportation Engineering Technical Committee 4A-20. In many developing countries, motor vehicles have rapidly grown as their cities become employment and trade centers. Developing rapidly developing countries have the environment needed to compete for the country but lack the resources to develop road facilities. Therefore, there are significant differences among developing countries in terms of traffic engineering characteristics, norms and traffic management technologies. In order to summarize the identification of their own experiences so that they can be applied to other countries, especially developing countries, the United States has established a research and development
