It analyses the determinants of transport mode use for journey to work among population groups considered as vulnerable to mobility and accessibility limitations. Using the 2001 Census of Canada, multilevel multinomial logistic regression models were estimated to assess the personal, social and economic factors that affect travel mode use of low-income persons in their journey to work in urban areas in Ontario and Quebec. The findings show important differences in the factors associated with car driving and public transit, between genders, and according to income level, educational achievement, household structure and immigration status. Furthermore, it is found that significant factors affecting travel mode use among low-income people in various urban areas are differentiated by province. The results point towards a geographic-based and balanced promotion of public and private mobility programmes and policies to address transport needs of low-income workers.","PeriodicalId":49416,"journal":{"name":"Transportmetrica","volume":"21 4 1","pages":"157 - 179"},"PeriodicalIF":0.0,"publicationDate":"2012-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/18128602.2010.539413","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59925655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article presents a mixed-behaviour multi-class equilibrium model for investigating heterogeneous drivers’ responses to route guidance and parking information systems in stochastic and time-dependent networks. The proposed model simultaneously considers the drivers’ choices of departure time, route and parking location under network uncertainty. All drivers are differentiated by their values of time and values of reliability, and each class of them is further divided into two groups, equipped and unequipped with ATIS, respectively. Suppose that the equipped drivers can predict travel disutility more accurately than the unequipped ones due to the information services provided by ATIS. The model is formulated as a fixed-point problem and is solved by a heuristic solution algorithm via a combination of the Monte Carlo simulation approach and the method of successive averages. The effectiveness of the modelling framework is illustrated by a numerical example and some new insights about the complex travel and parking behaviour under ATIS are obtained.","PeriodicalId":49416,"journal":{"name":"Transportmetrica","volume":"8 1","pages":"105 - 129"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/18128600903568570","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59925518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the time invariant safety assumption may be invalid, Hauer (1997) proposed a modified empirical Bayes (EB) method. Despite the modification, no attempts have been made to examine the generalisable form of the marginal distribution resulting from the modified EB framework. Because the hyper-parameters needed to apply the modified EB method are not readily available, an assessment is lacking on how accurately the modified EB method estimates safety in the presence of the time variant safety and regression-to-the-mean (RTM) effects. This study derives the closed form marginal distribution, and reveals that the marginal distribution in the modified EB method is equivalent to the negative multinomial (NM) distribution, which is essentially the same as the likelihood function used in the random effects Poisson model. As a result, this study shows that the gamma posterior distribution from the multivariate Poisson–gamma mixture can be estimated using the NM model or the random effects Poisson model. This study also shows that the estimation errors from the modified EB method are systematically smaller than those from the comparison group method by simultaneously accounting for the RTM and time variant safety effects. Hence, the modified EB method via the NM model is a generalisable method for estimating safety in the presence of the time variant safety and the RTM effects.","PeriodicalId":49416,"journal":{"name":"Transportmetrica","volume":"8 1","pages":"131 - 147"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/18128601003680976","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59925190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
