| 摘要： | The identification of technical, operational, and safety issues was accomplished primarily through a comprehensive literature search and a series of expert workshops. The literature search included identification and review of a broad range of previous AHS, IVHS, and related topic research and findings. This work supported a preliminary identification and/or confirmation and detailed description of major technical features, for example, (1) geometric design characteristics such as interchange design, lane width, and median configuration and (2) vehicle characteristics such as braking and acceleration capabilities. Accident type and severity data were also obtained and analyzed for various roadway categories and roadway improvements. Considering improved safety as a primary driver for the implementation of AHSs, current accident statistics were examined carefully to assess their potential utility as an indicator of likely AHS benefits. A summary of freeway design and operating characteristic information was developed not only to guide the ongoing work in this activity area, but to serve as a key point of reference for the team's other seven activity areas throughout the remainder of the program. |
