Book Description

This research is part of an overall effort to develop cost effective techniques for direct access control that will optimize traffic operational efficiency and safety subject to providing sufficient and suitable access to commercial properties on arterial highways. The research involved (1) a preliminary evaluation to select feasible and cost- effective candidate techniques, and (2) the development of detailed experimental procedures for evaluating the effectiveness of these candidate techniques. The scope of research was limited to control of direct access to commercial properties on two-lane and multilane highways with unlimited access, where traffic volumes are high enough to produce a hazardous situation. The emphasis was on the control of direct access on existing urban and suburban routes under state highway department jurisdiction.
