Intersection of two-way and one-way streets

The meeting of one- & two-way streets provides an opportunity lớn redesign the intersections lớn be more compact, reducing pedestrian crossing distances và reclaiming public space. Rethink intersection geometry, signal timing, & traffic volumes khổng lồ formulate a thiết kế that clarifies the hierarchy of street users, while enhancing the safety& legibility of the intersection.

This example illustrates an intersection where a wide, one-way street—with three travel lanes và curbside parking— meets a two-way street with two travel lanes in each direction.

At these intersections, cyclists and pedestrians suffer from long exposure times when crossing the street.

Large corner radii encourage high-tốc độ turns while the absence of refuge space fails lớn convey safety within the busy intersection. Stop lines that are either too cthua trận lớn the pedestrian crossings or not marked limit the capathành phố of motorists khổng lồ react in a situation of risk.

Unregulated parked vehicles may encroach on the pedestrian crossing & expose vulnerable users khổng lồ turning vehicles & oncoming traffic.

This reconstruction demonstrates the use of curb extensions, bus bulbs, và refuge islands to create a safer & more balanced intersection.

Maintain one mixed traffic lane on the one-way street. Introduce a dedicated transit lane & a parking-protected cycle track by removing a travel lane and offsetting the parking lane.

The dedicated transit lane is designed khổng lồ be a shared right-turn lane to lớn allow a moderate volume of right turns. The curb is extended to within 6 m of the lane’s edge lớn reduce the effective turn radius, slowing right turns và protecting pedestrians crossing.

 Extkết thúc ground markings for cycle lanes through the conflict zone of the intersection, matching the width & positioning of the leading cycle lanes. Manage turns across the cycle track using a leading cycle/lagging left-turn phase.

 Where transit is in mixed traffic on the two-way street, avoid conflicts at transit stops by raising cycle lanes và changing markings. This helps to reduce cycling speeds và provide at-grade access to transit passengers. In such a configuration, cyclists must yield topedestrians.

 On the one-way street, create pedestrian refuge islands in line with the parking lane to reduce pedestrian crossing distance. Where geometry allows, install refuge islands.

 Bus bulbs provide a dedicated space for passengers khổng lồ wait, improving transit travel times with more efficient boarding. Far-side transit stops are preferred in conditions in which conflicts with turning vehicles are common.

 Provide turn lanes by introducing a recessed central median on the two-way street. Turn lanes provide protected turns across oncoming traffic.

Thủ đô New York City, USA. A pedestrian refuge island và green infrastructure strategies are aligned with the parking lane, reducing crossing distances và increasing the safety of the intersection.
