可持续发展绩效评价在交通、能源管理、城市规划等领域受到广泛关注。鉴于交通已成为城市温室气体排放的主要组成部分，将可持续绩效评估与交通排放相结合对城市可持续发展至关重要。针对城市发展与城市中心活动区交通可达性不平衡的问题，基于改进的引力模型，提出了一种衡量城市可持续发展绩效的指标--潜在交通吸引力。同时，通过GPS轨迹生成交通吸引力与高排放交通量之间的相关性，保证了相关性模型对高排放出行方式的可信性。在此基础上，分析了日本东京中心活动区的发展现状，并针对不同的可持续发展状况提出了相应的对策。研究结果表明，城市发展与交通一体化具有巨大的减排能力，可为城市可持续发展的城市规划和交通政策提供具体指导。
Sustainable performance assessment has received extensive attention in the fields of transportation, energy management, and urban planning. Given that transportation has become a leading component of urban greenhouse gas emissions, combining sustainable performance assessment with transportation emissions is crucial to urban sustainability. In this study, pointed at the unbalance between urban development and transportation accessibility among urban central activities zones, a metric named potential traffic attraction is proposed based on improved gravitational model to measure urban sustainable performance. Meanwhile, the correlation between the traffic attraction and the high-emission traffic is generated via GPS trajectories, which could ensure the credibility of high-emission travel mode for the correlation model. Based on the obtained urban sustainable performance, the status of the central activities zones development in Tokyo(Japan) was analyzed, finally, several corresponding strategies in different sustainable development status were proposed. Our study demonstrated that the integration of both urban development and transportation owns tremendous capabilities for reducing vehicle emissions, and it could provide specific guidelines for urban planning and transportation policies on urban sustainable development.
