摘要
自动驾驶汽车对城市空间生长影响的研究未得到足够重视。通过系统梳理自动驾驶汽车的技术特性和影响,选取新增出行、道路通行效率和出行时间成本作为参数变量,建立改进的土地利用-交通模型。基于共享性和交通流特性构建不同的自动驾驶场景,运用模型分析和可视化技术,以U市为实例模拟评估不同自动驾驶场景下城市空间生长形态的变化。结果表明,所有场景下的交通可达性均有效提高,但城市空间呈现蔓延或集聚等不同的生长趋势。研究结论对制定自动驾驶环境下的城市空间交通、城市发展战略和政策具有参考意义。
Research on the impact of autonomous vehicles on urban spatial growth has not received suffi- cient attention both at home and abroad. Through systematically analyzing the technical characteristics and impacts of autonomous vehicles, this paper develops an improved land use-transportation interaction mod- el taking induced travels, traffic efficiency and travel time cost as parameters. Based on sharing and traffic flow characteristics in different autonomous vehicles scenarios, the paper simulates urban spatial growth in City-Using modelling analysis and visualization techniques. The results show that the transportation acces- sibility is effectively improved in all scenarios, while the urban space presents different growth trends in- cluding sprawl and agglomeration. The research conclusions is of reference significance for the formula- tion of urban space and urban transportation development strategies and policies facing under the environ- ment of autonomous vehicles.
