A combined and robust modal-split/traffic assignment model for rail and road freight transport

Agent-based Planning and Simulation of Combined Rail/Road Transport

A simulation model of the flow of Intermodal Terminal Units (ITUs) among inland intermodal terminals is presented. The intermodal terminals are inter-connected by rail corridors. Each terminal serves a user catchment area via a road network. The terminal is modelled as a set of platforms, which are served by a number of gantry cranes and front lifters. Given the schedule of train connections am...

The Environmental Impacts of Increased International Road and Rail Freight Transport

Service Quality and its Importance for Rail Freight Customers

Liberalisation process has just started in the Turkish rail market with the new law recently entered into force in order to comply with EU Directives. In the liberalised markets, service quality is the decisive factor that rail undertakings can use to create difference and achieve competitive advantages. The purpose of this paper is to analyse the customer perceived service quality for rail fre...

Single-Car Routing in Rail Freight Transport

Cars in rail freight service follow prescribed routes from their origin via intermediate shunting yards to their destination. The goal in designing such routes is to reduce the number of trains and their travel distances. Various real-world hard constraints make the problem difficult to formulate and also to solve. We present integer programming formulations for this car routing problem arising...

Concurrent Locomotive Assignment and Freight Train Scheduling

The locomotive assignment and the freight train scheduling are important problems in railway transportation. Freight cars are coupled to form a freight rake. The freight rake becomes a train when a locomotive is coupled to it. The locomotive assignment problem assigns locomotives to a set of freight rakes in a way that, with minimum locomotive deadheading time, rake coupling delay and locomotiv...
