Analysis of Work-Zone Crashes Using the Ordered Probit Model with Factor Analysis in Egypt
Work-zones, due to their nature, are predisposed to hazardous situations. This is a consequence of conducting construction work within the vicinity of, or near, vehicular traffic. The exposure to … [Read more...] about Analysis of Work-Zone Crashes Using the Ordered Probit Model with Factor Analysis in Egypt
Risk Factors Affecting Crash Injury Severity by Work Zone Area
Work zones include advance warning area, transition area, and activity area. The geometric, traffic control aspects, traffic operations, and driver’s maneuverability differ within each work zone area. … [Read more...] about Risk Factors Affecting Crash Injury Severity by Work Zone Area
