GAO-02-1075T Mass Transit: Challenges in Securing Transit Systems
We appreciate the opportunity to speak with you today about mass transit safety and security in the United States. Over a year has passed since the terrorist attacks of September 11, 2001, realigned our national priorities. While most of the early attention following the September 11 terrorist attacks focused on airport security, emphasis on the other modes of transportation has since grown. Mo...
متن کاملScalable Randomized Patrolling for Securing Rapid Transit Networks
Mass Rapid Transit using rail is a popular mode of transport employed by millions of people in many urban cities across the world. Typically, these networks are massive, used by many and thus, can be a soft target for criminals. In this paper, we consider the problem of scheduling randomised patrols for improving security of such rail networks. Similar to existing work in randomised patrols for...
متن کاملAgentC: Agent-based System for Securing Maritime Transit (Demonstration)
Recent rise in maritime piracy prompts the search for novel techniques for addressing the problem. We therefore developed AgentC, a prototype system that demonstrates how agent-based traffic management techniques can be used to improve the security of transit through piracy-affected areas. Combining agent-based modeling and simulation of maritime traffic and novel route planning and vessel sche...
متن کاملAgentC: agent-based system for securing maritime transit
• Produces optimized non-uniform set of speed levels • Enables dynamic, traffic-responsive grouping • Reduces transit times and attack rates compared to the existing group transit scheme with fixed schedules and uniform speed levels Randomized Transit Routing • Randomizes vessel transit routes to make them maximally unpredictable and reduces attack rates • Utilizes the transit game model (twopl...
متن کاملFleet Size and Frequency in Rapid Transit Systems
Given is a set of stations linked by railway tracks, forming an undirected railway network. One or more lines are formed in this network. Each line consists of an origin station, a destination station, and a number of intermediate stations. In order to complete the line configuration, you need to decide the frequency (number of services per hour) and the capacity (number of carriages) for each ...
