| Strategy Implementation & Monitoring Effectiveness: Operational Improvements
Projects geared toward improving the “supply side” of the transportation system. These efforts are intended to enhance the operation of the transportation system and make it as efficient as possible.
Traffic Signal Improvements
Signal hardware upgrades, signal software upgrades, signal timing, signal coordination, or (in conjunction with intersection improvements) channelization of turning movements.
Intersection / Geometric Improvements
Addition or reconfiguration of turning lanes, lane widening, realignment of intersecting streets, improved acceleration or deceleration lanes at interchange ramps.
Elimination of Bottlenecks
Removal of a physical constriction which delays travel, such as widening an underpass, providing lane continuity (i.e. replacing a two-lane bridge that connects pieces of four-lane roadway), or eliminating a sight barrier.
One-way Streets
Establishing, or removing, pairs of one-way streets in place of a standard two-way street.
Reversible Lanes
Establishing signals, signage, and pavement markings which permit the direction of travel to be changed during peak travel hours.
Ramp Metering
Signals at points where ramps enter a freeway, which regulate the rate and spacing of traffic entering the freeway based on actual conditions.
Incident Management Systems
Technology and programs for detecting crashes, disabled vehicles, or other incidents that impede travel and resolving or removing the obstructions.
Access Management
Policies, design criteria, and facilities that minimize the number of driveways and intersecting roads accessing a main thoroughfare; includes parallel service roads, shared driveways, median barriers, and curb cut limitations.
Intelligent Transportation Systems (ITS)
The use of technology to improve traffic flow.
