of the Bingham Street off-ramp
PI: Panos D. Prevedouros, Associate Professor
Assistants: B. Lee (MSCE), S. Su and L. Zhang (PhD)
Sponsor: Highways Division, Hawaii DOT -
HDOT Project Manager: Karl Kunishige
Project Duration: October 2000 - July 2001
The Hawaii Department of Transportation (HDOT) closed the Bingham
St. off-ramp throughout October 2000 in response
to complaints by residents about speeding and other adverse effects caused
by off-ramp vehicular traffic. The objective of the experimental closure
is to ascertain whether a permanent closure is feasible.
The evaluation consists of analysis and before-after comparisons of:
- volume patterns on several freeway, arterial and local street
cross sections
- speeds on Bingham St. about 300 ft. past the off-ramp and at
upstream and downstream detector stations on EB H-1 Freeway
- queues on upstream (Punahou) and downstream (University,
King) off-ramps
- residents' and motorists'perceptions of change in the situation via a
mail-back questionnaire survey
As of this writing, all data have been collected and more than 300 of the
1500 deployed surveys have been received.
Summary results and a comprehensive technical report will
be produced.
