Smaller version of standard roundabouts, designed for low-speed environments. Intended to slow traffic and improve intersection safety.

Reforming lanes to be narrower than standard widths. Intended to discourage speeding and create a perception of a confined space.

Narrowing of the street at intersection corners through curb extensions. Intended to reduce pedestrian crossing distance and slow down turning vehicles.

Road design without traditional traffic signals where all road users share the same surface. Intended to create a sense of uncertainty to reduce vehicle speeds.

Series of raised strips set into the pavement along the roadway. Intended to alert inattentive drivers through a vibratory and auditory effect.

Physical design elements such as curves and turns added to the road to slow down traffic. Intended to impede straight-through movements.

Decreasing the radius of the curb at intersections to slow the turning speeds of vehicles. Intended to improve pedestrian safety by reducing the exposure time in crosswalks.

Pedestrian crossings elevated to the level of the sidewalk. Intended to slow down vehicles and increase pedestrian visibility.

Safe waiting areas situated in the middle of larger streets for pedestrians. Intended to assist with the crossing of one direction of traffic at a time.

Raised areas of pavement designed to reduce vehicle speeds. Intended to enhance pedestrian safety and discourage speeding.

Traffic regulation that prohibits a right turn while the traffic signal is red. Intended to improve safety for pedestrians crossing the street.

Bridges allowing pedestrians and cyclists to cross over busy roadways. Intended to prevent accidents by separating traffic from vulnerable road users.

Sidewalk extensions at intersections or mid-block crossings that reduce the crossing distance. Intended to improve pedestrian visibility and safety.

Use of different materials or patterns in the road surface to indicate a change in driving conditions. Intended to alert drivers through tactile feedback.

Artificial features creating extra turns in the road to slow down traffic flow. Intended to reduce vehicle speeds and enhance the streetscape.

Circular intersection designs that promote continuous flow of traffic. Intended to reduce the incidence and severity of collisions.

Raised medians or islands within an intersection or mid-block to manage traffic movements. Intended to direct flow and improve pedestrian safety.

Entrance treatments to influence driver perceptions and indicate transition into an area where different driving behavior is expected.

Electronic signs that display a vehicle’s speed as it approaches, often with messages or symbols. Intended to raise awareness and encourage speed compliance.
