Impact of highway geometry and posted speed on operating speed at multi-lane highways in Egypt
The paper presents an analysis of roadway factors and posted speed limits that affect the operating speed at multi-lane highways in Egypt. Field data on multi-lane highways in Egypt are used in this investigation. The analysis considers two categories of highways. The first consists of two desert roads (Cairo-Alexandria and Cairo-Ismailia desert roads) and the second consists of two agricultura...
متن کاملModeling the Operational Speed of Tangents and Curves in Four-lane Highways Based on Geometric and Roadside Factors
Operational speed is an index that represents drivers’ speeding behaviors and shows the comfort and safety levels they experience. Many models had been proposed to predict operational speed in tangent and curve segments of highways. Most of these works had used geometric, with few of them conducted using roadside variables to predict operational speed. Also, the operational speed study in multi...
متن کاملTwo-Lane Highways: International Perspective
The results of an extensive literature review of the safety performances of lowand intermediate-traffic-volume, two-lane rural highways are presented. The effects on traffic safety, as measured by accident rates, of pavement width, radius of curve/degree of curve, gradient, sight distance, traffic volume, and design speed on curved sections of two-lane rural highways are covered. The following ...
متن کاملAnother look at the safety effects of horizontal curvature on rural two-lane highways.
Crash Modification Factors (CMFs) are used to represent the effects on crashes of changes to highway design elements and are usually obtained from observational studies based on reported crashes. The design element of interest for this paper is horizontal curvature on rural 2-lane highways. The data for this study came from the Washington State database in the Highway Safety Information System ...
متن کاملModelling Free Flow Speed on Two-lane Rural Highways in Bosnia and Herzegovina
Free flow speed is used as a parameter in transportation planning and capacity analysis models, as well as speedflow diagrams. Many of these models suggest estimating free flow speed according to measurements from similar highways, which is not a practical method for use in B&H. This paper first discusses problems with using these methodologies in conditions prevailing in B&H and then presents ...
