The EU strategy is now (2006) based on modal shift, decoupling and technological innovation, weakening the more radical strategy set up in 2001. It seems that expansion of the EU, lower levels of growth, and the possibilities of continuing high costs of oil have resulted in changing priorities, but above all travel demand has continued to grow. The Kyoto targets are becoming much harder to reach. The paper then outlines the three groups of measures that have been promoted, looking at (1) technology and pricing, (2) regulation, taxation and congestion charging, and (3) land use, development and planning, arguing that strong action is required on all three sets of options. Even then, there is an additional requirement, namely the need to gain public acceptability through information, marketing and engagement so that positive outcomes can be matched up with policy intentions. Real progress towards reducing carbon emissions is possible provided that mutually supporting measures are taken, with political commitment to real change and public support for that change.","PeriodicalId":49416,"journal":{"name":"Transportmetrica","volume":"3 1","pages":"106 - 91"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/18128600708685668","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60522881","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 design of the scheme is also normally constrained by several practicality requirements. One of the practicality requirements which is tackled in this paper is the topology of the charging scheme. The cordon shape of the pricing scheme is preferred due to its user-friendliness (i.e. the scheme can be understood easily). This has been the design concept for several real world cases (e.g. the schemes in London, Singapore, and Norway). The paper develops a methodology for defining an optimal location of a multi-concentric charging cordons scheme using Genetic Algorithm (GA). The branch-tree structure is developed to represent a valid charging cordon scheme which can be coded using two strings of node numbers and number of descend nodes. This branch-tree structure for a single cordon is then extended to the case with multi-concentric charging cordons. GA is then used to evolve the design of a multi-concentric charging cordons scheme encapsulated in the two-string chromosome. The algorithm developed, called GA-AS, is then tested with the network of the Edinburgh city in UK. The results suggest substantial improvements of the benefit from the optimised charging cordon schemes as compared to the judgemental ones which illustrate the potential of this algorithm.","PeriodicalId":49416,"journal":{"name":"Transportmetrica","volume":"3 1","pages":"41 - 71"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/18128600708685667","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60523096","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}

In this transportation system, several classes of users with different perceptions and behavior are considered. Their demands are continuously distributed over the city, and their travel patterns to the CBD satisfy the user equilibrium conditions under which each individual user chooses the least costly route in the continuum to the CBD. A logit-type demand distribution function that incorporates housing rent and travel cost is specified to model the housing location choice behavior of the commuters. A bi-level model is set up for modeling the housing allocation problem in the continuum transportation system. At the lower level, a set of differential equations is constructed to describe this housing location and traffic equilibrium problem. We present a promising solution algorithm that applies the finite element method (FEM) to solve this set of differential equations. At the upper level, a constrained minimization problem is set up to find the optimal housing provision pattern that maximizes the total utility of the system. The FEM and convex combination method are proposed to solve the minimization problem with the sensitivity information from the lower level. A numerical example is given to show the workability of the proposed bi-level model and the effectiveness of the solution algorithm.","PeriodicalId":49416,"journal":{"name":"Transportmetrica","volume":"3 1","pages":"21 - 39"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/18128600708685666","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60522933","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}

Although this field is relatively mature, many new research directions are being pursued; at the same time practitioners experience ongoing difficulties with applying commercial software systems in correct and meaningful ways. China is presently undergoing rapid urbanization, implying major investments in road and transit systems, as well as airports and intercity surface transportation systems. Wise investment decisions require forecasts of future urban travel in China's congested cities. To understand the state of travel forecasting, the authors recently held discussions with professionals at several planning agencies of China's largest cities, as well as university departments engaged in related teaching and research. Our objective here is to relate the general findings and impressions from these discussions, as well as the message we presented to the seminar participants.","PeriodicalId":49416,"journal":{"name":"Transportmetrica","volume":"3 1","pages":"1 - 19"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/18128600708685664","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60522459","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}
