基于碳排放的城市干道信号协调控制

Signal Coordination Control of Urban Arterial Road Based on Carbon Emission

以福州市仓山区金山大道上3个重要节点为研究对象,以碳排放和路段总延误为评价指标,应用Synchro交通仿真软件进行信号协调控制优化设计,实现了交叉口碳排放最小的交通管理策略。研究结果表明:信号协调控制比现状单点信号控制方案的碳排放和路网总延误分别减少了9.6%和13.5%。可见,干道信号协调控制能有效减少碳排放,并提高交通流的运行效率。

The objective of study were three key nodes located in Jinshan Road, Cangshan District, Fuzhou City.Taking ＂the carbon emissions and total delay＂ as the evaluation index, ＂Synchro＂ traffic simulation software was applied in the optimal design of signal coordination control. The mainline traffic flow ＂carbon emissions minimum＂ traffic management strategy was established. The results showed： signal coordination control was reduced by 9.6 %and 13.5 % respectively compared with the single point signal control scheme. Obviously, arterial signal coordination control can effectively reduce carbon emissions, and improve the running efficiency of traffic flow.
