Abstract: A mathematical model is described for estimating approach delays at pretimed, signalized, coordinated intersections. The delay models incorporate the size of and flow rate within the progression bandwidth. Platoon dispersion ...

Abstract: The formulation of a mixed integer‐linear programming model to determine a minimum‐cost flexible pavement design is presented. The model identifies the number, type, and thicknesses of paving materials required to meet the ...

Abstract: This research explores factors associated with driver yielding behavior at unsignalized pedestrian crossings and develops predictive models for yielding by using logistic regression. It considers the effect of variables ...

Abstract: This paper presents a decision-making framework based on a travel time reliability methodology developed under the U.S. Strategic Highway Research Program. Existing methods consider a set of predefined prevailing conditions ...

Abstract: Existing models for estimating left turn capacity assume an average opposing flow rate throughout the cycle. While this assumption may be valid under random arrivals, it is evident that the presence of platoons results in ...

Abstract: Real-time traffic data are the lifeline sustaining the operation of Advanced Traffic Management and Advanced Traveler Information Systems (ATMS/ATIS). Data are essential to drive algorithms related to congestion/incident ...

Abstract: This paper presents a decision-making framework based on a travel time reliability methodology developed under the U.S. Strategic Highway Research Program. Existing methods consider a set of predefined prevailing conditions ...

Abstract: An auxiliary through lane (ATL) is a commonly used congestion relief measure at signalized intersections in which fiscal and right-of-way constraints do not allow for full widening between intersections. Previously developed ...

Abstract: A comprehensive, multidisciplinary study of traffic control needs of freeway lane closures at work zones included surveys of drivers and highway patrolmen, test driver studies, field measurements of merging and speed ...

Abstract: A critical element in assessing traffic performance at the individual lane level at signalized intersections is the knowledge of traffic volumes in each lane. Typically, turning movement volumes are available only for the ...
