This report evaluates criticism of rail transit systems. It examines claims that rail transit is ineffective at increasing public transit ridership and improving transportation system performance, that rail transit investments are not cost effective, and that transit is an outdated form of transportation. It finds that critics often misrepresent issues and use biased and inaccurate analysis. Th...

Background & objectives: The urban rail transport network is always at risk due to its special conditions. Many cases indicate the existence of threatening and risk factors for human societies in urban rail transportation systems. Therefore, in this study, with the aim of identifying and prioritizing the risks of urban rail transportation networks in order to increase resilience is on the agend...

The paper discusses requirements for freight modelling and presents specific approaches concerning freight surveys, demand and network modelling, rail freight optimisation and freight assignment including: • Surveying methods for collecting road based demand data. • WIVER/VISEVA: a demand modelling system for urban and regional commercial transport. • SPIN: a multimodal network model for interm...

Rail shipments of hazardous materials expose the population near the routes to the possibility of an accident resulting in a spill. Rail routes are determined by economic concerns such as route length and the revenue generated for the originating carrier. In this paper we consider an alternate routing strategy that takes accident risks into account. We employ a model to quantify rail transport ...

In recent years, the rail transport has achieved rapid development. In assuming the responsibility of promoting the transport task of the economic development, it also faces greater challenges of the rapid growth of passenger volume and safety guarantee. To carry out research on rail traffic safety assessment has essential theoretical and practical significance in protecting public property and...

in this paper, we propose a sensitivity analysis for evaluating the effectiveness of recovery solutions in the case of disturbed rail operations. indeed, when failures or breakdowns occur during daily service, new strategies have to be implemented so as to react appropriately and re-establish ordinary conditions as rapidly as possible. in this context, the use of rail simulation is vital: for e...
