A typical urban traffic network is a complicated large-scale stochastic system which consists of many interconnected signalized traffic intersections. Thls paper develops a decentralized real-time adaptive control strategy for the traffic networks based on Markov decision theory. Computer simulation results of this new approach on a five intersection traffic network indicate significant improve...

Signalized intersections on high-volume arterials are often congested during peak hours, causing a decrease in through movement efficiency on the arterial. Much of the vehicle delay incurred at conventional intersections is caused by high left-turn demand. Unconventional intersection designs attempt to reduce intersection delay and travel time by rerouting left-turns away from the main intersec...

The Government of Quebec is currently considering the introduction of right turn on red (RTOR) at signalized intersections in Quebec, with the possible exception of the City of Montreal. The Province of Quebec and New York City are the only jurisdictions in North America where the RTOR is not permitted. Following more than 25 years of intense political debates, the Government agreed in 2000 to ...

the highway safety manual [hsm, 2010] recommends safety evaluations be performed beforeimplementing any roadway treatment to predict the expected safety consequences. safety consequences canbe measured using crash prediction models, crash modification factor (cmfs), or both. this paperdevelops a cmf to show the expected impact of red-light cameras (rlcs) on safety at signalizedintersections. a ...
