Benefits of Radio-Based Train Control to improve URBAN RAIL service and reduce life-cycle costs

摘要

The paper will review an open-standards radio-based data communication system solution for CBTC and reference the first application, the Las Vegas Monorail, inaugurated summer 2004, and application to Paris Metro's Line 13. The data communication system has two major components, a wired trackside network, and a wireless component that bridges the gap between the wired trackside network and trains. These components together form a single Ethernet IP network with standard IEEE 802.3 interfacing. The wireless component is deployed using Commercial-Off-The-Shelf (COTS) IEEE 802.11 radios. Emerging wireless standards such as IEEE 802.16 and IEEE 802.20 offer a stable future migration path. With such global interest in standardization, it makes sense that industries such as rail should not be left behind but should rather seek out the benefits that can be derived.
