在全面分析交通效率内涵的基础上,提出了4种交通效率度量方法,即可达性、机动性、生产率、效用方法。分析了各种方法的优点与局限性。对珠江三角洲两个城市高速公路网络交通效率的验证分析表明这4种方法意义明确、算法简便。经进一步的理论分析,可以认为,这4种度量交通效率的方法将为规划工程师和决策人员提供直观、丰富而又简练的信息和决策帮助。
Based on a comprehensive analysis of the connotation of traffic efficiency, four traffic efficiency measurement methods are proposed, namely accessibility, mobility, productivity and utility methods. The advantages and limitations of each method are analyzed. The verification and analysis of the traffic efficiency of expressways in the two cities in the Pearl River Delta shows that the four methods have clear meaning and the algorithm is simple and convenient. After further theoretical analysis, it can be considered that these four methods of measuring traffic efficiency will provide planning engineers and decision makers with an intuitive, rich and concise information and decision-making assistance.
