For urban rail transit network, the space-time flow distribution can play an important role in evaluating and optimizing the space-time resource allocation. For obtaining the space-time flow distribution without the restriction of schedules, a dynamic assignment problem is proposed based on the concept of continuous transmission. To solve the dynamic assignment problem, the cell transmission mo...

The train derailment is one of the major accidents in rail transit safety system. The reach uses collision accident of rail transit train in Tokyo and Shanghai as the case. Firstly, it present fishbone diagram to qualitatively analysis main factors in derailment. Then it set up a derailment accident tree model with the qualitative and quantitative analysis of. The results show that illegal oper...

The neglectof the rail sector in Brazil that went on for decades is fortunately being overcome, especially in the metropolitan region of São Paulo, with the subways and monorails, an example to other Brazilian metropolitan regions. The historical disconnection between the passenger transport modals combined with the increasing private vehicle fleet and the lack of investment in mass transit sys...

There is a great need for estimation of passenger flow temporal and spatial distribution in urban rail transit network. The literature review indicates that passenger flow assignment models considering capacity constraints with overload delay factor for in-vehicle crowding are limited in schedule-based network. This paper proposes a stochastic user equilibrium model for solving the assignment p...

This publication is a follow-up study to MTI publication 00-01, Why Campaigns for Local Transportation Funding Initiatives Succeed or Fail: An Analysis of Four Communities and National Data. The earlier publication was case studies of four local ballot tax measures for transportation packages. The current study, Factors Influencing Voting Results of Local Transportation Funding Initiatives with...

This paper deals with the threshold radius that warrants the use of single restraining rail for transit and railroads. Different railways use different threshold radius from 91m to 365m to provide restraining rail. These threshold figures are probably experience driven choices. The need for restraining rail may be related to a so-called derailment alarm coefficient of 1.2 sustained over 2m leng...

Bus Rapid Transit (BRT) has the potential to bridge the gap between conventional rubber-tired transit operations and rail systems. Based on relatively low-cost, proven technology, BRT is gaining acceptance in many communities around the world that are endeavoring to provide high-quality transit service. While proposed applications of this new mode vary considerably, some conditions may be more ...

A rapidly growing demand and shortage of electric energy require mankind to efficiently use it, recuperate store it from the existing system, when possible, for further applications whenever need arises. Electric trains figure among big consumers different railway transportation services; light rail transit are characterized by frequent stoppings entrain detrain passengers. In their operation, ...
