No full textForecasting the use of new local railway stations and services using GIS
No full textThe aim of this thesis is to develop an integrated methodology for investigating thepotential for new local railway stations within a given area, with particular emphasis on theuse of Geographical Information Systems (GIS). Existing methods for assessing the casefor constructing new local railway stations have often been found wanting, with theforecasts produced proving to be inaccurate.A review of previous work in this field has been undertaken and methodologies with thepotential to enhance local rail demand models have been identified. Trip rate and trip endmodels have been developed which are capable of forecasting usage at new station sitesanywhere in England and Wales. Geographically Weighted Regression (GWR) has beenused to enhance the performance of these models and to account for local variations in theeffects of explanatory variables on rail demand. Flow level models have been producedfor stations in South-East Wales, with a range of model formulations tested. A survey ofultimate passenger trip origins and destinations was carried out in the same area, enablingthe accuracy of theoretical station catchment definition methods to be tested.A GIS-based procedure for locating potential sites for new railway stations within a givenarea has been developed. This was combined with the results from the demand models andestimates of associated costs and benefits to give a synthesised appraisal procedure capableof assessing the case for constructing particular stations. This procedure was applied to 14sites in South-East Wales and, along with trip end forecasts for 421 sites across thecountry, this indicated that there is almost certainly a positive case for constructing asignificant number of new railway stations in the UK

Trip end models of local rail demand in England and Wales
No full textThis paper details models which have been developed to forecast the total number of trips made from local rail stations in England and Wales over a one year period.The use of multiple linear regression and geographically weighted regression in calibration are compared, with both explaining over 75% of the variation in the observed data. The latter technique has not previously been used in rail demand modelling, and allows significant spatial variations in the effect of independent variables to be identified and mapped.A number of catchment definition methods are investigated, as is the inclusion of a wide range of demographic and service related explanatory variables. The models developed are used to forecast usage at stations on the recently opened Ebbw Vale branch line in South Wales and these predictions are compared to initial usage figures<br/
System and Route Planning
No full textThis chapter covers the range of issues which need to be considered when planning a new railway route or system. These issues are grouped under the three main aspects of sustainability: social, environmental and economic, while noting that there are inevitably some overlaps between them. This chapter therefore provides information which can help ensure that a holistic and comprehensive consideration of sustainability is embedded in the planning process. It also discusses how the various impacts associated with the construction and operation of a new railway route or system can be compared and assessed in order to determine whether or not a proposed rail scheme should go ahead.</p
‘Sleepers Awake? The impact of market liberalisation on the evolution of overnight rail services in Europe’
No full textThe provision of night trains in Europe has been gradually declining for several decades, as a result of the liberalisation of short-haul aviation and the expansion of daytime HSR services. There are though increasing signs of a revival in demand for overnight services, accompanied by a number of proposals for additional night train services. However, the expanded networks that are emerging seem likely to be profoundly unequal, with some city pairs being served by multiple operators while other major cities and regions are omitted entirely. This paper aims to assess the relative importance of political, regulatory, operational, financial and social factors in driving spatial and temporal variations in the provision of night train services in Europe. It will analyse changes in the pattern of overnight rail services in Europe over the last century, focusing particularly on the impact of changing levels of market liberalisation and the involvement of private operators. The factors driving the current evolution of the network will then be assessed, to investigate the extent to which different barriers inhibit the operation of night train services in certain areas. Finally, the paper will consider whether regulatory changes could facilitate development of a more comprehensive Europe-wide night train network
Fine-grained traffic state estimation and visualisation
Full text linkTools for visualising the current traffic state are used by local authorities for strategic monitoring of the traffic network and by everyday users for planning their journey. Popular visualisations include those provided by Google Maps and by Inrix. Both employ a traffic lights colour-coding system, where roads on a map are coloured green if traffic is flowing normally and red or black if there is congestion. New sensor technology, especially from wireless sources, is allowing resolution down to lane level. A case study is reported in which a traffic micro-simulation test bed is used to generate high-resolution estimates. An interactive visualisation of the fine-grained traffic state is presented. The visualisation is demonstrated using Google Earth and affords the user a detailed three-dimensional view of the traffic state down to lane level in real time
