| 摘要： | This article describes the Federal Highway Administration's (FHWA's) WesTrack pavement testing facility in Reno, Nevada. The primary objectives of the current research at the facility are the development of performance-related specifications for hot-mix asphalt pavement construction and the early field validation of the Strategic Highway Research Program Superpave (trademark) performance-prediction models and complete mixture analysis procedures. In addition the project has supported the development and use of driverless vehicles to allow safer operation of the repetitive WesTrack pavement loading. The WesTrack driverless vehicle program has been successful and is an operational real-world example of heavy-vehicle driverless operation. It has addressed the practical requirements for control system redundancy and for continuous, vehicle safety and vehicle-health monitoring that will be part of practical automated highway systems. WesTrack has been operating with four driverless triple-trailer combinations since June 1996. More than 700,000 kilometers of driverless operation have been recorded to date. Fail-safe controls have been implemented, and a practical level of reliability has been achieved. A system of continuous, vehicle safety monitoring has also been demonstrated. |
