Hit-and-run in a collision is a punishable offence as it delays crash notification thereby delaying emergency response which increases the likelihood of traffic fatality. To obtain a better understanding of hit-and-run behavior, a logistic regression model has been applied in this study to identify the factors that might affect the occurrence of hit-and-run(More)
Conventional traffic simulator systems do not support Connected Vehicles (CV). The focus of this study is to extend the functionality of a traffic simulator and developing APIs for Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication. We use the extended simulation system to examine the implementation of advisory speed recommendation(More)
Since speeding is one of the major causes of frequent and severe traffic accidents around school and playground areas, many jurisdictions have reduced the speed limits in these areas to protect children who may be at risk. This paper investigated the speed compliance, mean speed and 85th percentile speed at selected school and playground zones in the City(More)
The objective of this paper is the development of a multi-criteria optimization framework for the simultaneous calibration of demand and supply parameters in DTA. The presented approach estimates origin-destination (OD) flows and calibrates the driver behavioral and route choice parameters in a complex network modeled in Paramics microscopic traffic(More)
This paper presents sensitivity analysis results for a distributed evolutionary implementation of the estimation of time-dependent origin-destination (TDOD) matrices. The system uses a noniterative origin-destination (OD) estimation process, which attempts to minimize the discrepancy between observed link flow counts and assigned counts. At the same time,(More)
Tornadoes are a destructive form of the extreme weather associated with thunderstorms. Canada gets more tornadoes than any other country with the exception of the US. This paper presents some results of a study on tornado mitigation in the Canadian Prairie region. Initially, a regression-based analysis of the Prairie tornado database was conducted, and the(More)
