Timetable Optimization

Timetable optimization techniques offer opportunity for saving energy and hence reducing operational costs for high-speed rail services. The existing energy-saving timetable optimization is mainly concentrated on the train running state adjustment and the running time redistribution between two stations. Not only the adjustment space of timetables is limited, but also it is hard for the train to reach the optimized running state in reality, and it is difficult to get feasible timetable with running time redistribution between two stations for energy-saving. This paper presents a high-speed railway energy-saving timetable based on stop schedule optimization. Under the constraints of safety interval and stop rate, with the objective of minimizing the increasing energy consumption of train stops and the shortest travel time of trains, the high-speed railway energy-saving timetable optimization model is established. The fuzzy mathematics programming method is used to design an efficient algorithm. The proposed model and algorithm are demonstrated in the actual operation data of Beijing-Shanghai high-speed railway. The results show that the total operating energy consumption of the train is reduced by 3.7%, and the total travel time of the train is reduced by 11 minutes.

The development of high-speed railway has been very fast, while there are still existing many problems to be further studied and discussed, especially the design of high-speed railway Train stops program. The research of classification of high-speed passenger railway nodes has a vital significance for forecast of high-speed railway passenger flow, passenger train operation plan, evaluation and optimization and so on, especially for highspeed railway stopping schedule .This paper analyzes the significance and methods of high-speed passenger railway nodes classification, and designs high-speed rail train line stops program based on the classification. Finally, analyzing the case on the basis of Beijing-Guangzhou high-speed railway, a train stops program will be made bases on the classification of Beijing-Guangzhou high-speed railway passenger transport nodes to verify the feasibility of this study.

Quo Vadis

For many years the South African government has put forward policies and strategies to improve and promote public transport. Despite this, very little has changed over the last 30 years, although projects such as the Gautrain high-speed rail service and a few bus rapid transit routes have been introduced recently. These projects, however, are not integrated in a logical manner into the broader public transport system and are often referred to as stand alone interventions because of a lack of managing public transport in terms of integrated transport plans. The traditional commuter rail, bus and 16-seat taxi industries therefore operate in policy silos and, in the case of the bus and rail industries, are planned and funded independently of each other, leading to a further lack of integration. Policy interventions have been implemented partially or not at all, leaving the public transport sector in a state of flux. The methodology followed in researching this paper was to briefly trace the historical public transport policy developments, with a focus on the commuter bus industry, in order to identify possible impediments to policy implementation and to identify policy interventions for addressing the currently stalled policy implementation programme. The main finding of the paper is that it would be advisable to establish provincial transport authorities between local and provincial governments. That should speed up the development and implementation of integrated transport plans, which ought to lead to integrated public transport systems and a more optimal spend of the available governmental funds aimed at subsidising public transport.

From operation management strategy perspective, a multi-objective time-space network optimization model of train energy consumption on a high speed rail line is proposed on the basis of train time table predetermined. The models objectives are to minimize circulation of rail stock and total energy consumption, and decision variables are number of train units in stations, while constraints include node flow conservation, passenger demand and capacity limitation. Finally, a simulation case is provided and solved for comparison and an optimization analysis is carried on via weighting method to illustrate the models feasibility and effectiveness.

Very few contributions in the literature have dealt with the issue of social exclusion related to High Speed Rail systems. The objective of this manuscript is to understand what are the factors excluding users from choosing High Speed Rail services considering as case study Spain. For this purpose, a Revealed Preference survey was employed in November and December 2015. A questionnaire was submitted to users of the Spanish transport systems travelling for long distance-journeys. The aim was that of investigating their perception of High Speed Rail system and the factors inhibiting passengers or excluding them from its use. Data about their socioeconomic characteristics were collected as well. The main result of the survey has been that a relationship between social exclusion and High Speed Rail in Spain is present, especially in terms of geographical exclusion.DOI: http://dx.doi.org/10.4995/CIT2016.2016.3100

AbstractThe priorities assessment for the planned construction of high-speed rail/HSR in the Czech Republic in terms of impacts on internal and external integration is a though-provoking topic not only from the technical and economic, but also from the social and geographical point of view. Its primary basis is the application of the gravity model, according to which the planned route C Prague-Wien has the most significant potential in passenger transport. Then following routes are A Prague-Berlin, B Prague-München, and D Brno-Katowice. Subsequently, the likely impacts generated by a significant improvement in the quality parameters and hence the competitive position of rail transport were assessed, including the potential for shifting part of the demand from the road and air transport to HSR. Overall, however, it can be stated that the potential impacts of the HSR on the growth of passenger transport in the Czech Republic will not be essential. To perceive the regional impacts of HSR construction, analyses of selected indicators (population density per km2, GDP per capita, unemployment rate) by NUTS 3 regions for the period 2007-2017 were also carried out. From the strategic point of view, the research results did not confirm that the planned construction of the HSR primarily stimulates convergence tendencies in regional development as the main priority of EU regional policy. Rather, it seems more likely that the HSR will stimulate the extraction of economic activity from “rural” regions in favour of metropolitan regions.

The paper deals with comparative analyses of the main competing transport modes in terms of the planned construction of high-speed rail / HSR. In the conditions of the Czech Republic, it is practically only bus transport and individual car transport (including relevant alternative types of transport). In this context, based on available data from traffic statistics, the existing traffic flows in passenger transport on the roads corresponding to the planned HSR routes are analysed. The main goal of the article is to present the results of comparative analyses of transport modes representing the most important potential competitors of the planned HSR and the subsequent synthesis of the obtained results. In accordance with the fact that the key destination is of course Prague, followed by Brno, especially their planned interconnection using HSR (assuming an adequate supply of a competitive solution) has greatest potential for shifting part of demand from bus but also from individual car transport to rail.
