We propose and analyze a generic mathematical model for dynamic, stochastic vehicle routing problems which we call the dynamic traveling repairman problem (DTRP). The model is motivated by applications in which the objective is minimizing the wait for service in a stochastic and dynamically changing environment. This is a departure from traditional vehicle routing problems which seek to minimiz...

Emergency vehicles (ambulances, police cars and fire trucks) are deployed for rescuing people in an emergency. Crash statistics for Alberta, Canada indicate that more than 300 road traffic accidents every year involve at least one emergency vehicle. The aim of this study is to identify the factors that may have an influence on the probability of injury in crashes involving emergency vehicles in...

Traffic congestion worldwide has led to loss of human lives due to failure in transporting accident victims, critical patients, medical equipment and medicines on time. With the unending growth in vehicular traffic everywhere, Internet of Things (IOT) and Vehicular Ad Hoc Network (VANET) have embarked as a promising platform for an Intelligent Traffic Management System (ITMS). Many researches h...

This paper explores the notion and usefulness of nonstationary velocity profiles for high priority emergency vehicle transit on automated highways. These profiles are intended for use in the link layer of the hierarchical control architecture defined by the California Partners for Automated Transit and Highways (PATH) program. A non-stationary velocity profile which can be used to circulate tra...

A vehicle routing problem is a significant problem that has attracted great attention from researchers in recent years. The main objectives of the vehicle routing problem are to minimize the traveled distance, total traveling time, number of vehicles and cost function of transportation. Reducing these variables leads to decreasing the total cost and increasing the driver's satisfaction level. O...

This paper proposes an advanced distribution automation planning problem in which emergency-based demand response plans are incorporated during service restoration process. The fitness function of this planning problem consists of various costs associated with fault occurrence in electric distribution systems consisting of the total yearly cost of customers’ interruptions, the total annualized ...
