A study of no-passing zone configurations on two-lane highways in North Carolina. Volume 1: Summary and highlights of research methodology and findings, including guidelines for use and application of simulation model.

A study was undertaken to investigate the relationships between the independent variables of percent of the total length of a section of highway marked with no-passing barriers and the traffic volume input to the section of highway, and the dependent throughout variables of mean speed change cycles. Multiple linear regression equations and graphs are developed for the variables. The conclusions are that a digital computer model for traffic simulation can be employed to represent and duplicate traffic flow on two-lane, two-way rural highways.
