Constructing new highway systems is unlikely to mitigate this problem since available land is limited. On the other hand, physically increasing the supply of transportation systems would cause increased traffic demand, and consequently, the traffic problems may not be improved or resolved. Therefore, managing traffic requires using Transportation (or Travel) Demand Management (TDM). TDM has been one of the main strategies used to improve traffic problems in major cities around the world. In this study, the level of satisfaction towards the existing TDM strategies for road users in Taipei city is explored. As for the strategies not yet implemented, the level of acceptance is also analysed. Finally, a stated choice experiment is carried out to capture the traveller's choice behaviour under different scenarios of TDM strategies. We apply the nested logit model to analyse the satisfaction and acceptability with executed and unexecuted TDM strategies, compare the similarities and dissimilarities within work, shopping and leisure trips and discuss the relationship between variables. We find that travellers agree that disincentive strategies, also known as ‘Sticks’, could solve the problems of traffic jams, but their acceptance or satisfaction is lower than their feeling of effectiveness of TDM strategies. Besides, shortening the travel time of mass transportation tools is an important factor to increase travellers’ willingness to use them.","PeriodicalId":49416,"journal":{"name":"Transportmetrica","volume":"7 1","pages":"201 - 228"},"PeriodicalIF":0.0,"publicationDate":"2011-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/18128600903421424","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59925298","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 goal of this article is to assess the distributive impacts of the widely-used four-step, demand-based, transport model. This article starts from the hypothesis that the consecutive application of the four-step model over a number of years, and successive investments in transport infrastructure consistent with the model results, will widen existing gaps between high-mobile and low-mobile groups, in terms of transport facilities and accessibility available to each group. A simplified four-step model is then developed to test the hypothesis under different policy scenarios. The results are mixed. In each scenario, gaps between high-mobile and low-mobile groups are increasing and decreasing at the same time. Against expectations, the distributive implications of demand-based modelling seem to depend on the situation and the focus of analysis. Given the unpredictable distributive impacts, it is suggested that explicit justice indicators be incorporated in transport modelling if it is to contribute to a more just distribution of transport facilities and accessibility over population groups.","PeriodicalId":49416,"journal":{"name":"Transportmetrica","volume":"7 1","pages":"181 - 200"},"PeriodicalIF":0.0,"publicationDate":"2011-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/18128600903322333","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59925202","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 metric includes static and dynamic complexity, both consisting of the complexity component for arriving and departing traffic. The main objective of the developed metric is as follows: evaluation of particular alternative solutions for airspace organisation and design and related air traffic complexity under the given circumstances, which could be used for planning purposes at the strategic and the tactical level. For this reason, the proposed metric reflects the expected complexity over a certain time period, rather than the current value of complexity. The main factors influencing complexity of a given TMA are: configuration of TMA, which implies among other factors, the number and length of arrival/departure trajectories, the airport(s) runway system capacity, air traffic volume, aircraft fleet mix, spatial distribution of traffic and the air traffic control separation rules. Unlike most other approaches, the one presented in this article disregards the air traffic controller workload issue from explicit consideration, but indicates the level of complexity which could influence the workload that he or she could be faced with under the specified circumstances. The output consists of complexity values dependent of the configuration, i.e. three-dimensional geometry of the given TMA and approach/departure trajectories in it, air traffic volume, aircraft fleet mix and the spatial distribution of traffic. The developed complexity metric has been applied to TMA traffic around London Heathrow Airport, UK.","PeriodicalId":49416,"journal":{"name":"Transportmetrica","volume":"7 1","pages":"369 - 394"},"PeriodicalIF":0.0,"publicationDate":"2011-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/18128602.2010.505590","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59925411","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}
