Today’s highway administrators are operating in a more customer-conscious environment than in the past. Currently, however, expert judgments are used widely in lieu of road-user input. A comprehensive framework for studying and modeling public perceptions of quality of service (QOS) in a highway system is provided. The framework demonstrates how it is possible to observe the phenomena of drivers’ perceptions of QOS and to apply them in the context of highway planning. Some of the results from a pilot implementation of the concepts are presented for illustrative purposes. A multiyear research effort is proposed for developing tools that will allow decision makers to consider the perceptions of highway users in decision making.

This report documents the findings of a project to identify improved means to collect, manage, and use crash, inventory, traffic, and other data to design safer highways. Improved safety information is essential to making effective design decisions and formulating sound policies for the design of vertical and horizontal alignments, cross sections, roadside treatments, and traffic controls. The contents of this report are, therefore, of immediate interest to highway and facility designers and those concerned with systemwide safety improvement programs.
