Road Profiles, Vehicle Dynamics, and Human Judgment of Serviceability of Roads: Spectral Frequency Domain Analysis
Publisher: American Society of Civil Engineers
Abstract: The serviceability rating of roads has been an interesting and important subject ever since it was introduced to measure the road performance. The present paper analytically addresses this problem—namely, linking a static ...
Road Profile, Vehicle Dynamics, and Ride Quality Rating
Publisher: American Society of Civil Engineers
Abstract: A great deal of research has been carried out over the past few decades in seeking explanatory variables to understand various human judgmental indices of road quality. The essential question is, What is a rater sensing ...
New Approach to Roadway Performance Indices
Publisher: American Society of Civil Engineers
Abstract: In 1964, Carey and Irick defined the present serviceability index (PSI) by assuming that the PSI can be expressed on a scale of 0 to 5 as the sum of a logarithmic function of slope variance, a quadratic function of mean ...
Microscopic Simulation of Traffic in Networks: Supercomputer Experience
Publisher: American Society of Civil Engineers
Abstract: The use of microscopic traffic‐simulation codes in practice and in research has generally been limited by available computational resources to very small portions of an urban area's network. Supercomputers offer an ...
