As the material basis for vehicular network, road infrastructure network plays an important role in transportation. Reasonable road network density and traffic demand work as a good foundation for easing the traffic pressure. Based on the defined road grid cell in a grid network, this paper proposes a model to estimate the floor area ratio upper limit from the perspective of traffic demand-supply equilibrium. Based on a typical scenario, an automatic tool was designed, and some parameters were set up to do numerical simulation. The simulation results indicate that the floor area ratio upper limit and the road grid cell area followed the power-law distribution, and the approximate power exponent was −0.866. When the private car percent transferred to 1% of the public transport, the floor area ratio upper limit increased by 2.8%. In the meanwhile, the economic benefits increased by RMB 44.8 million at a road grid cell of 40,000 m² with the floor area ratio of 2. Finally, it is found that a simple floor area ratio value is deficient in comparison with the current floor area ratio regulations of Jinan. And the corresponding road grid cell area can’t be neglected and should be comprehensively considered.

基于道路网格单元的车辆基础设施网络占地面积比估算

道路基础设施网络作为车辆网络的物质基础，在交通运输中起着重要的作用。合理的路网密度和交通需求是缓解交通压力的良好基础。基于网格网络中定义的道路网格单元，从交通需求-供需平衡的角度出发，提出了一个模型来估算建筑面积比上限。基于典型场景，设计了一种自动工具，并设置了一些参数进行数值模拟。仿真结果表明，容积率上限和道路网格单元面积遵循幂律分布，近似幂指数为-0.866。当私家车的百分比转移到公共交通的1％时，建筑面积比率上限增加了2.8％。与此同时，²用的2。最后的容积率，可以发现，一个简单的容积率值与济南的当前容积率法规比较欠缺。相应的道路网格单元面积不可忽略，应综合考虑。
