Choke Point

Description:
 
Choke Points are curb extensions placed mid block to narrow the roadway to 14' or the equivalent of one travel lane.
 
Purpose:
 
Choke Points are intended to reduce traffic volumes by making the roadway narrow so that only one car at a time can pass through it.
 
Effectiveness:
 
Choke Points are still in the testing phase and have not been tried on Portland Streets.
 
Cost:
 
Choke Points cost should be approximately $7,000-10,000 each.
 
Parking Impacts:
 
Parking will not be allowed at the choke Point. This should remove only one parking space, or 20', from each side of the road.
 
Transit Service Impacts:
 
Choke Points should not impede transit service but might effect scheduling.
 
Emergency Services Impacts:
 
Emergency response vehicles. The Choke Points testing will include a study of the effects on Fire Bureau vehicles. The Fire Bureau will decide if this device can be used on streets that serve as a primary response route.
 
Noise Impacts:
 
Choke Points should not generate noise.
 
Other Considerations:
 
Traffic volumes should decrease when Choke Points are constructed. The degree of volume reduction has yet to be determined in testing.
 
Choke Points will not be constructed on Neighborhood Collectors.
 
Examples In Portland:
 
Testing locations for Choke Points have not been determined.
