摘要
铁路车站导向标识为旅客提供导向和信息服务,是旅客站内路线判断和空间位置顺畅转换的主要依据,科学合理地选择导向标识布点能够更好地辅助旅客自主获取引导信息,提供清晰、准确和高效的导向服务。根据客流流线将车站空间结构抽象为网络拓扑图,以客流导向需求为约束、最大化区域诱导信息量为目标构建导向标识布点的优化模型,根据解的空间特性设计模拟退火算法并利用Matlab实现。实例验证表明,利用该模型和算法求解导向标识布点决策实际问题,验证模型有效性和求解算法的良好性能。
The direction signs in rail station guide passengers to their destinations, and rational direction sign layout scheme provides its target people more information and better guidance service. Based on passenger flow in rail station, a optimization model is set up for direction sign layout by means of maximizing quantity of direction information in certain area as objective, and diversifying direction demands as constraint. The simulated annealing algorithm is designed according to the characteristics of the model and implemented by Matlab. The model effectiveness and the algorithm performance are verified by practical layouts of direction sign in rail station.
