Detroit uses many traffic engineering techniques and methods to reduce congestion and speed traffic flow. Success is most frequently obtained by use of a mix of methods on a single street. Streets have been widened and laned, traffic channeled with left turns restricted or prohibited, parking prohibited, and a flexible progressive signal system devised to accommodate heavy peak flow. Freeways are the latest method of increasing traffic capacity and have reduced congestion on many surface streets. Where congestion still exists, it is because funds are not available to apply the proper remedies.
