one-way street

One Way Street is a 1950 film noir directed by Hugo Fregonese featuring James Mason, Märta Torén and Dan Duryea. The crime film takes place mainly in Mexico.

One-way traffic (or uni-directional traffic) is traffic that moves in a single direction. A one-way street is a street either facilitating only one-way traffic, or designed to direct vehicles to move in one direction. One-way streets typically result in higher traffic flow as drivers don't have to deal with oncoming traffic nor turns through oncoming traffic. Residents may dislike one-way streets due to the circuitous route required to get to a specific destination and the potential for higher speeds affecting pedestrian safety. Some studies even challenge the original motivation for one-way streets in that the circuitous routes negate the higher speeds.
