Examination Of Factors Affecting The Frequency, Response Time, And Clearance Time Of Incidents On Freeways, Indrajit Ghosh Jan 2010

Examination Of Factors Affecting The Frequency, Response Time, And Clearance Time Of Incidents On Freeways, Indrajit Ghosh

Wayne State University Dissertations

Traffic incidents are the primary cause of non-recurrent congestion in urban areas, resulting in reductions in roadway capacity and significant safety hazards to other motorists, as well as first responders. Many communities have initiated incident management programs that detect and respond to incidents and restore freeways to full capacity by clearing the incident scene as soon as possible. In the Detroit metro area, the Michigan Department of Transportation (MDOT) operates a Freeway Courtesy Patrol (FCP) program as part of its larger freeway incident management program from the Michigan Intelligent Transportation Systems (MITS) Center in downtown Detroit. The MITS Center maintains …


Flexible Pavement Rut Depth Modeling For Different Climate Zones, Asmaiel Kodan Naiel Jan 2010

Flexible Pavement Rut Depth Modeling For Different Climate Zones, Asmaiel Kodan Naiel

Wayne State University Dissertations

Pavement rutting is one of the most important types of pavement distress that affect road safety and ride quality. Therefore, the primary objective of this study was to develop pavement rutting empirical models for different climate zones to predict pavement rutting on granular base based on LTPP data. Flexible pavements with granular base course were considered for this study. These models lead to better understanding of rutting phenomena and the factors that may have affect in pavement rutting. In addition, these models will help state and local transportation agencies make accurate decisions for maintenance, rehabilitation and reconstruction of pavement.
