A utility-based travel impedance measure for public transit network accessibility

摘要: Abstract A utility-based travel impedance measure is developed for public transit modes that capable of capturing the passengers’ behaviour and their subjective perceptions when travelling in networks. The proposed time-dependent it estimates realisation by community passengers between an origin–destination (OD) pair. main advantage measure, as compared to existing measures, relates its capability diversity benefit systems may offer society travellers with different traveling preferences. To clarify necessity such capability, we demonstrate randomness (subjectivity) perceived passengers, through evidence from observed path choices made network greater Brisbane metropolitan region Australia. basically a nested logit “logsum” composition over generated set reasonable options whose systematic utilities are evaluated based on discrete choice model previously calibrated passengers. As case study, calculated all origin blocks area, during morning commutes Central Business District (CBD). results presented discussed, intuitive important advantages demonstrated measure.
