A cumulative prospect theory-based user equilibrium(CPT-UE) model considering stochastic perception error(SPE) within travelers' route choice decision process is developed. The SPE is conditionally dependent on the actual travel time distribution, which is different from the deterministic perception error used in the traditional logit-based stochastic user equilibrium. The CPT-UE model is formulated as a variational inequality problem and solved by a heuristic solution algorithm. Numerical examples are provided to illustrate the application of the proposed model and efficiency of the solution algorithm. The effects of SPE on the reference point determination, cumulative prospect value estimation, route choice decision and network performance evaluation are investigated.展开更多

The study found, different identity, qualifications, age, background of Shanghai＇ s Public perception to air quality perform a universal character, and the rate of concerning for air pollution is relatively high, but to air pollution, they lack of understanding of its essence. Shanghai＇s public have a large usage of mobile devices, the way of concerns for air quality shows a ＂move concern＂ feature. There is a certain influence of air quality on public＇s travel decisions, on the condition that public often go out and show their concern on air quality information.展开更多
