Abstract:For the past several years researchers have attempted to describe "level of service" in both qualitative and quantitative terms. There is a need to establish parameters that: (1) reflect the quality of the trip or "level of service" afforded the motorist, and (2) are predictable for a given set of conditions. The energy-acceleration noise model is an attempt to apply a quantitative value to the many of the qualitative characteristics of traffic flow considered in the "level of service" concept. Also, an attempt is made to find a much-needed quantitative value for measuring the effect of geometries on the quality of traffic flow. The correlation of traffic behavior and design is the key to the level of service concept. This report follows the pattern characteristic of research reports of the Texas Transportation Institute, i.e., development of theoretical concepts, verification through experimentation and finally a discussion of the application of the findings.
