Patrol Scheduling in an Urban Rail Network
This paper presents the problem of scheduling security teams to patrol a mass rapid transit rail network of a large urban city. The main objective of patrol scheduling is to deploy security teams to stations of the network at varying time periods subject to rostering as well as security-related constraints. We present several mathematical programming models for different Variants of this proble...
متن کاملAn Approach to Calculate Overall Efficiency of Rolling Stock for an Urban Rail Transit System
Inefficiency of urban rail transit systems (URTS) results in a lower standard of service than required and has negative economic impacts. Many efforts have been undertaken to calculate the efficiency of URTS or their subunits. Overall equipment efficiency (OEE) as a measure of efficiency is a simple, flexible, and efficient formula. The OEE measure ensures that equipment is available and fully ...
متن کاملNetwork Centrality Analysis of Tehran Urban and Suburban Railway System
Nowadays, Tehran Urban and Suburban Railway System (TUSRS) is going to be completed by eight lines and 149 stations. This complex transportation system contains 168 links between each station pairs and 20 cross-section and Y-branch stations among all eight lines. In this study, we considered TUSRS as a complex network and undertook several analyzes based on graph theory. Examining e.g. centrali...
متن کاملEmergency Management of Urban Rail Transportation Using CBTC System
Urban rail transit systems are rapidly developing around the world. Due to a great deal of urban traffic pressure, improving the efficiency and capacity of urban rail transit systems is an increasing demand. Because it is a key subsystem of urban rail transit systems, communication-based train control(CBTC) is an automated train control system that makes use of train–ground wireless communicati...
متن کاملUrban Rail Transit System Operation Optimization A Game Theoretical Methodology
The Urban Rail Transit (URT) has been one of the major trip modes in cities worldwide. As the passengers arrive at variable rates in different time slots, e.g., rush and non-rush hours, the departure frequency at a site directly relates to perceived service quality of passengers; the high departure frequency, however, incurs more operation cost to URT. Therefore, a tradeoff between the interest...
