Much of recurring congestion is due to physical bottlenecks -- potentially correctable points on the highway system where traffic flow is restricted. While many of the nation's bottlenecks can only be addressed through costly major construction projects or costly transportation alternative solutions (ie: high occupancy vehicle or toll lanes, dynamic pricing, investments in transit alternatives, etc.), there is significant opportunity for the application of operational and low-cost "fixes" at spot-specific locations. This book provides guidance to state and local transportation personnel on how to overcome barriers and challenges with reference to the implementation of localised congestion relief projects.
