Simulation of Westbound Interstate H-1 Freeway Between the Airport Viaduct
and Waikele During Weekday Afternoon Peak
PI: Panos D. Prevedouros, Associate Professor
of Civil Engineering
Assistants: Jerry Ji (Ph.D.), James Watson (MSCE)
Sponsor: Oahu Metropolitan Planning Organization (20%) and Federal Highway
Administration (80%) - HDOT Project Manager: Ronald Tsuzuki
Project Duration: February 2004 - December 2006
A number of potential alternatives (some of which are already in the
planning or design stages) will be investigated for this extremely
congested section of the H-1 freeway. Most investigations will be
conducted using macroscopic (KRONOS9 and FREQ12) and microscopic
(INTEGRATION and VISSIM) traffic simulation models.
Once a reliable representation of current traffic conditions has been
established, the freeway simulation model can be used to determine:
- Traffic impacts of the additional westbound lane on the Waimalu
Viaduct.
- The need for and benefits of adding a second lane to off-ramp 8-B to
Waipahu (after a westbound lane is added on the Waimalu Viaduct).
- The need for and benefits of adding a fourth lane to westbound H-1
through
the Waiawa Interchange (after a westbound lane is added on the Waimalu
Viaduct).
- Traffic impacts of modifying high occupancy vehicle (HOV) lane
requirements.
- Benefits and drawbacks of adding a westbound afternoon contraflow lane
which merges into the northbound H-2, westbound H-1, or both at the Waiawa
Interchange.
- Benefits and drawbacks of metering access to the westbound H-1 from
the
Aiea/Halawa on-ramp, H-3 on-ramp, or both.
- Impacts from the proposed Nimitz Hwy. viaduct addition.
- Combinations of various scenarios selected by a technical oversight
committee.
