StrategyMeasureDescription

Vertical deflectionSpeed bump Making slow points on residential complexes
Speed hump Making slow points on roadways
Speed table Making slow points on roadways
Speed cushion Making slow points on roadways suitable for bus routes
Rumble strip Alerting unaware drivers to the changes in traffic condition and environment
Raised Crosswalk/intersection Enforcing drivers to give way to pedestrians at crosswalks to intersections

Horizontal deflectionChicane Making slow points on roadways
Lateral shift Making slow points on roadways
Center island Chicane Making slow points on roadways
Traffic circle Making slow points at intersections

NarrowingChoker Reducing the width of roadways at midblock locations
Bus bulb Curb extension to improve the safety of passengers
Neck-down Reducing the width of roadways at intersections
Road diet Reducing the number of lanes and the effective width
Sidewalk widening Widening sidewalk to improve pedestrian activities
Pedestrian refuge island Improving the safety of pedestrian when crossing wide streets
Hatched markings Reducing the effective width of roadways
Turn lane Assigning a turn lane in the middle of roadways to reduce effective width of roadways
Median Constructing raised median to reduce the effective width of roadways

Pavement treatmentPavement treatment Using alternative materials to alert drivers to changes in traffic condition and environment

Parking managementParking Restriction/prohibition Restricting or prohibiting on-street parking to improve the safety of pedestrians and other vulnerable road-users
Nonparallel parking Different types of parking to reduce the effective width of roadways

Volume controlFull closure Closing streets to thru traffic
Half closure Closing one-half of roadways
Diagonal diverter Managing streets to discourage thru traffic
Turn prohibition Closing streets at particular times to discourage thru traffic

StreetscapingStreet furniture Enhancing the social aspect of streets
Tree planting Enhancing the environmental aspect of streets
Gateway Inform drivers about changes in traffic zone

Changes to speed limitSpeed limit reduction Reducing current speed limit
Heavy vehicle speed limit Different speed limits for trucks
School zone Reducing speed limit at school times
