Roundabouts

With pedestrian facilities only!

Roundabouts

Great formula for moving cars

Or is it?

• Sidewalks shall be separated for way finding.

• Where pedestrian crossings are more than one lane, pedestrian-activated signals shall be provided.

Landscaped separation to indicate crossing location.

Possible separation solution for curb attached sidewalks

Identifying gaps with no visual cuesMulti-threat crash is large issue for large RBTs

Raised Crosswalks may help

Single-Lane

• Single-lane are a little simpler to navigate

Multi-Lane

• Multi-lane need signalization

• This is not ‘reality’ it is Visualization

What kind of signal????

RRF Beacon?

Still Need AccessiblePedestrian Signal (APS)

This is not an APS

Pedestrian Hybrid Beacon (HAWK)?

Accessible Pedestrian Signal (APS)

Locator tone then walk indication

PROWAG will likely require the following:• …there shall be a continuous and detectable

edge treatment (not DWS) along the street side of the walkway wherever pedestrian crossing is not intended…

• …at roundabouts with multi-lane crossings, a pedestrian activated ‘signal’ (with APS) shall be provided for each multi-lane segment…

• …where pedestrian crosswalks are provided at multi-lane right or left channelized turn lanes at roundabouts, a pedestrian activated ‘signal’ (with APS) shall be provided…
