Two distinct formulations, namely the non-normalised nested logit and utility-maximising nested logit models, have been proposed to estimate discrete choice models with mixed revealed preference and stated preference data, in which each data type has the multinomial logit or nested logit form. The article uses two alternative nested logit model formulations to demonstrate how to correctly set up tree structures for estimating nested logit models with mixed preference data. This article provides formulae for recovering correct utility function, dissimilarity and scale parameter estimates. Estimations and correction procedures are empirically illustrated and can be applied to other nested logit models with multiple data sources.","PeriodicalId":49416,"journal":{"name":"Transportmetrica","volume":"6 1","pages":"291 - 309"},"PeriodicalIF":0.0,"publicationDate":"2010-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/18128600903401236","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59925262","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}

The airline network design problem aims to determine hub location, flight routes and flow allocation. The hub location decision is a long-term investment and will not vary according to different demand levels. On the other hand, the determination of flight routes and flow allocation are short-term decisions and may change due to seasonal demand variation. A two-stage stochastic model was proposed to formulate the problem. The first-stage problem corresponds to hub location decision, while the second-stage corresponds to flight route determination and flow allocation based upon the hub location from the first stage and realised uncertain demand. Finally, a contrived network and a real network are used to test the proposed model.","PeriodicalId":49416,"journal":{"name":"Transportmetrica","volume":"6 1","pages":"187 - 213"},"PeriodicalIF":0.0,"publicationDate":"2010-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/18128600902906755","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59925000","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}

The DC models regress emissions on vehicle-related variables (i.e. direct factors), while the IC models further account for such variables (i.e. indirect factors) as driver/rider demographics, vehicle mileages travelled and regional types by using structural equation modelling. Results show that vehicle characteristics are the most influencing factors affecting hydrocarbon and carbon monoxide emissions. The old vehicles with small engine, manual transmission, high cumulative mileages travelled, using unleaded gasoline #92 and 2-stroke engine (for motorcycle) can be identified as ‘high-emitting’ vehicles. The second most influencing construct is the driver/rider demographics. The aged, male, low-educated car drivers and motorcyclists with high income and long driving/riding experience tend to use high-emitting vehicles.","PeriodicalId":49416,"journal":{"name":"Transportmetrica","volume":"6 1","pages":"215 - 233"},"PeriodicalIF":0.0,"publicationDate":"2010-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/18128600903168108","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59924788","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}

Vehicle fleet routing and timetable setting are not only important in inter-city bus carrier operations, but are also related to alliance effects. The setting of a good timetable cannot only enhance the allied inter-city bus carriers’ operating performance, but also be a useful reference for alliance decision-making. In this research, we develop several coordinated scheduling models by combining vehicle fleet routing and timetable setting. To evaluate the models, we perform a case study using real operating data from two Taiwan inter-city bus carriers. The preliminary results are good, showing that the models could be useful for inter-city bus carrier's alliances.","PeriodicalId":49416,"journal":{"name":"Transportmetrica","volume":"7 1","pages":"161 - 185"},"PeriodicalIF":0.0,"publicationDate":"2010-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/18128600902853197","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59924883","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}

The influence of slow vehicles (e.g. trucks) on traffic operations has been studied both from a micro and macroscopic level. Though multiclass traffic models have been successfully developed in literature, few of them are adequately used to describe traffic network operations. To this end, this article aims to propose a model to study the (heterogeneous) traffic network operations based on the macroscopic modelling approach. More specifically, on the one hand, we introduce an extension of the classic Lighthill–Whitham–Richards model to describe multiclass traffic operations in the network. The proposed model is based on solving a system of hyperbolic partial differential equations describing multiclass traffic dynamics with discontinuous fluxes. On the other hand, a dynamic routing algorithm is applied to determine the turning flow at nodes based on the information provision of the current network situation. Numerical results have shown that the proposed model can capture some real traffic phenomena in multiclass traffic networks.","PeriodicalId":49416,"journal":{"name":"Transportmetrica","volume":"6 1","pages":"121 - 141"},"PeriodicalIF":0.0,"publicationDate":"2010-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/18128600902857925","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59924930","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}

As such, without explicitly taking into account the negative effects of accidents on the outputs when measuring efficiency for bus transit, the interpretation of results could be misleading. To be more rational, this article proposes a stochastic production frontier model that incorporates the effects of accidents into the measurement. A case study with 10 Taipei bus transit carriers over 2001–2006 is carried out. The results show that the ranking of technical efficiency with consideration of accidents has significantly differed from that without accounting for accidents. The managerial implications suggest that bus carriers can level up their productive efficiency not only by means of decreasing the inputs and/or increasing the desirable outputs, but also by way of ameliorating their safety records.","PeriodicalId":49416,"journal":{"name":"Transportmetrica","volume":"6 1","pages":"79 - 96"},"PeriodicalIF":0.0,"publicationDate":"2010-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/18128600802630265","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60523623","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}

Structural Equation Modelling is used to construct a ‘satisfaction’ latent variable to relate air passenger perception on the airport ground access modes with the characteristics of the trip and of the passengers themselves. The ‘satisfaction’ latent variable is incorporated into the discrete choice model, which is used for evaluating the ground access modal split pattern at Hong Kong International Airport (HKIA). The model results indicated that satisfaction level is associated with mode utility. By incorporating the ‘satisfaction’ latent variable into the discrete choice model, air passenger ground access mode choice behaviour is then modelled more precisely. Hence, a better understanding on the demand for various ground access mode choices at HKIA can be obtained.","PeriodicalId":49416,"journal":{"name":"Transportmetrica","volume":"6 1","pages":"17 - 3"},"PeriodicalIF":0.0,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/18128600902929583","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59925124","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}
