考虑低碳的高铁客站新区路网结构优化

Optimization for Road Network Structure in High-speed Railway Station Considering Low Carbon

高铁客站新区聚集了大量的交通流,给周边路网交通和城市碳排放产生了很大影响.为保证畅通出行和低碳出行,以高铁客站新区道路网结构为研究对象,选取站区路网交通供需平衡和碳排放容积率最小作为站区路网结构优化的目标,建立了基于多目标的高铁客站新区道路网结构优化模型.以宜昌东站为例,结合相应的交通调查数据,应用建立的模型进行路网结构优化分析.结果表明:构建的站区道路网结构优化模型具有较好的适用性.

A large number of traffic flows have gathered in the new area of high-speed railway station,which has a great impact on the traffic of the surrounding road network and urban carbon emission.In order to ensure unblocked and low-carbon travel,the road network structure of high-speed railway station was taken as the research object.The balance of between supply and demand of the network traffic and the minimum volume ratio of carbon emission were selected as the optimization goal for the road network structure in station area,and a multi-objective optimization model for the road network structure in high-speed railway station area was established.Finally,the Yichang East Station was taken as an example,combined with the corresponding traffic survey data,the established model was applied to optimize the road network structure.The results show that the proposed road network structure optimization model of the station has good applicability.
