| 摘要： | The Advance Warning to Avoid Railroad Delays (AWARD) system is an Advanced Traveler Information Service (ATIS) implementation designed to help motorists avoid delays due to railroad operations that cross freeway access or frontage roads. It is a part of the Federal Highways Model Deployment Initiative (MDI) in San Antonio, Texas. The system includes Doppler radar sensors placed at selected locations along the railroad track to detect the presence, speed and length of trains before they approach grade crossings. Data from the sensors is transmitted to the TransGuide Control Center where computer programs calculate the predicted time and duration that grade crossings at or near freeway exits will be blocked. This information enables TransGuide operators to control changeable message signs placed at strategic locations along the freeway to alert motorists of potential delays ahead and allow them to select alternate exits. Information on blocked grade crossings is also placed in the Area Wide Data Base for use in other MDI components such as Kiosks and In-Vehicle Navigation. This document describes the tests to be performed and the results that are required in order to verify that the AWARD system is constructed and operates in accordance with the requirements specified in the AWARD System Design Document. Tests are generally divided into three sections: (1) The sensors physically located along the railroad track, (2) The railroad operational software, (3) The TransGuide Advanced Traffic Management System (ATMS) software as it is affected by the AWARD system. |
