Optimally minimizing delay times at signalized intersections can significantly improve both traffic flow and safety. However, most traffic flow optimizing tools do not measure the effect on safety. This study uses nonlinear programming (NLP) algorithms to optimally minimize delay times and employs both Safety performance functions (SPFs) and empirical Bayes (EB) before-after methodology to meas...

Road Traffic injuries are known as the most prevalent childhood injury and besides being the greatest cause of child mortality, place an extraordinary burden on health care system. Children’s limitation in cognitive, physical and social development makes them more vulnerable in road traffic injuries than adults. Their small structure cause challenges to see and be seen and their risk taki...
