- An uncontrolled crosswalk is in a location that lacks stop or signal control (e.g., midblock intersection). Pedestrians using marked crosswalks and drivers approaching these crosswalks require adequate sight lines so they can look for one another. Uncontrolled crosswalks may have HAWK signals or half signals.
- Methods for improving sight lines between a driver and pedestrian include:
- Installing yield lines
- Installing bulbouts
- Prohibiting parking between the yield line and crosswalk
- Methods of informing drivers that they need to look for crossing pedestrians include:
- Installing Roving Eye displays
- Installing Yield Here to Pedestrians signs (along with yield lines)
- Table 15.1 lists bulbout widths visible to motorists passing in the nearest travel lane.
