Rapid traffic growth in Calgary has put increased pressure in city's roadway network, especially on Deerfoot Trail which provides a fast access to north-south potion of the city. The city disseminates traffic information in Deerfoot through variable message sign (VMS) in case of major delays and...

With increasing concerns over the possibility of tornadoes in highly populated areas in Canada, emergency managers are looking into ways to mitigate the impacts of tornadoes. Given that tornadoes can cause enormous destruction, early warnings and proper evacuation actions are critically...

The Fe–Ni–Cr alloy is a potential material as bipolar plate for PEMFC (proton exchange membrane fuel cell), and the stamped metallic bipolar plate is a promising candidate instead of traditional graphite due to the advantages of mass production, low cost and excellent performance. The...

The aim of this study is to investigate the solution algorithm for solving the problem of determining reliable shortest paths in road networks with stochastic travel times. The availability of reliable shortest paths enables travelers, in the face of travel time uncertainty, to plan their trips...

This paper proposes a generalized model to estimate the peak hour origin–destination (OD) traffic demand variation from day-to-day hourly traffic counts throughout the whole year. Different from the conventional OD estimation methods, the proposed modeling approach aims to estimate not only...

This paper presents a novel reliability-based stochastic user equilibrium traffic assignment model in view of the day-to-day demand fluctuations for multi-class transportation networks. In the model, each class of travelers has a different safety margin for on-time arrival in response to the...

This paper proposes a novel traffic assignment model considering uncertainties in both demand and supply sides of a road network. These uncertainties are mainly due to adverse weather conditions with different rainfall intensities on the road network. A generalized link travel time function is...

This paper proposes a stochastic user equilibrium assignment model for congested transit networks, together with a solution algorithm. A mathematical programming problem is formulated, that is equivalent to the stochastic user equilibrium assignment model for congested transit system. When the...

Statistical models for the estimation of Origin-Destination (OD) matrix from traffic counts that consider explicitly the presence of randomness in the link choice proportions have been developed recently. These models are more receptive to the fluctuations in the observations due to measurement...

The use of statistical modeling in the estimation of Origin-Destination (OD) matrix from traffic counts is reviewed. In particular, statistical models that consider explicitly the presence of measurement and sampling errors in the observed link flows are discussed. This paper proposes treating...
