REVIEW AND CONSIDER TRAFFIC CONTROL OPTIONS FOR RIVER ISLANDS
PARKWAY AT THE INTERSECTIONS OF BOSCH AVENUE AND IMPERIAL DRIVE Staff evaluated these intersections utilizing the California Manual on Uniform Traffic Control Devices ( MUTCD).

The following options are being presented to Council for review and consideration:
Option 1 — Remove stop control and crosswalks ( Recommended) Approximate cost is $ 10, 000)
Pros:
o High pedestrian safety by concentrating pedestrians at the adjacent signalized and pedestrian activated flashing
intersections
o High vehicle safety by eliminating stop on River Islands Parkway, reducing potential for rear -end collisions
Cons: No protected right of way for vehicles or pedestrians on the side streets
Option 2 — Install a pedestrian hybrid beacon

Pros: Protected right of way for pedestrians crossing over River Islands Parkway
Cons:
o No protected right of way for vehicles on the side streets o Rear -end collisions on River Islands Parkway may increase due to sudden or unexpected stops
Option 3 — Install a traffic signal

REASON FOR RECOMMENDATION:

FISCAL IMPACT:
Staff estimate the approximate construction costs below for all the options for the two intersections:
