| | So far,there exist a number of literatures in evaluating the impacts of traffic information on travelers' travel choice behaviors in a transportation network with advanced traveler information systems (ATIS),but these literatures principally focus on commuters' route choice decisions.In this paper,a comprehensive effect of information provision on trip destination,modal split and route choice is investigated by utilizing the nested logit based choice structure model in discrete choice theory and st... | | 目前研究先进的旅行者信息系统对出行者选择行为的影响主要集中在对路径选择行为的影响上,而忽略了对出行者出行终点和交通方式选择的影响。假定路网中的出行者一部分装有信息装置,另一部分没有装信息装置,利用离散选择理论中的层次选择结构模型和交通规划理论中的随机均衡方法,研究了先进的旅行者信息系统对出行者终点选择,方式分担和路径选择行为的综合影响,建立了一个与网络均衡条件等价的数学规划模型,设计了模型的求解算法,并用一算例分析了市场渗透率和信息质量对出行者选择行为的影响。 | | 文摘来源 | | Road network reliability has attracted numerous interests from nowaday academic researchers and practitioners due to its vital significance to industrial operation,economical development and people's daily life.This paper systemically reviewed the updated research progresses of the road network reliability internationally and nationally regarding the various indices,models and frequently used approaches.In order to evaluate uncertainty of the road network,a stochastic network #... | | 回顾了路网可靠度模型的研究进展:包括不同的可靠度指标、模型以及算法。在分析传统可靠度模型优缺点的基础上,提出将随机网络平衡模型用于路网可靠度分析。 | | 文摘来源 | | Many commuters in modern cities take their travels to reach destinations by using park'n ride mode,where the first part of the trip is taken by private car and the remainder is completed by taking transit modes.This commuting mode,also called combined one,requires people to choose transfer points besides deciding routes.This paper employs the nested logit model in discrete choice theory to study the park'n ride behaviors in urban transportation networks.A mathematical programming model is established,... | | 在一次出行过程中,经常会使用停车-换乘方式,即出行的前一部分采用私家车方式,途中停车,再换乘其他交通方式到达目的地。在停车-换乘出行方式下,人们除了选择路径,还要选择换乘站点。利用离散选择理论中的层次Log it结构模型,研究城市交通网络中的停车-换乘行为,定义多模式下停车-换乘出行的混合随机均衡分配条件,建立与之等价的数学规划模型,设计模型的求解算法,并用一算例分析算法的收敛性能和模型参数及公交票价对解的灵敏度。 | | 文摘来源 | |   |
