|
|
•The INC-ZONE and RESP-STG applications are being assessed
primarily using microscopic traffic simulation.
|
|
•The Testbed that is being modeled for this purpose is the
US-101 freeway in San Mateo, California
|
|
•Testbed details:
|
|
- The corridor is an 8.5 mile long freeway
which forms a major connector between San Jose and San Francisco.
|
|
- The corridor presents a variety of
traffic control features such as HOV lanes, Ramp Metering etc. and carries an
AADT (Average Annual Daily Traffic) between 200,000 to 250,000 vehicles.
|
|
- Data required for baseline calibration
including incident data is available and is being used in the Testbed,
including PeMS data, California Highway Patrol logs etc.
|
|
•Simulation Conditions used:
|
|
- 5-hour PM peak simulation is used for
model calibration.
|
|
- Weather conditions used: Dry and Rainy
weather conditions.
|
|
- Incident types: Short incident (30
minutes) and Long incident (60 minutes)
|
|
- Levels of market-penetration of the
applications: 10%, 25%, 50%, 75% and 100%
|
|
•Modeling Capabilities:
|
|
- The modeling of INC-ZONE and RESP-STG
applications is being done in VISSIM 7 traffic simulation software.
|
|
- Functionalities used:
|
|
•Lane-alerts and warnings are modeled as commands to change
the vehicle’s desired lanes.
|
|
•Speed-alerts and warnings are modeled as commands to change
the vehicle’s desired speed distribution.
