Task Order 4106
Joy Dahlgren, PATH Headquarters
joy@uclink.berkeley.edu, http://www.path.berkeley.edu/PATH/General/Staff/jdahlgren.html
There are two basic goals for this project. The long term goal is to develop a simulation capability to be used in 1)analyzing the effects of new traffic management statregies 2)analyzing the effects of applying existing strategies in specific situations, and 3)developing and testing traffic theory. The short term goal is to use Paramics to evaluate the effects of ramp metering on I-680 on the Sunol Grade, so as to be able to assess the effects to the cities that would be affected by the ramp metering.
Task Order 4115
Carlos Daganzo, University of California, Berkeley

This project will develop a theory of access control for systems where route choice effects can be ignored, but including internal queues on freeways and the resulting storage benefits. Our goal is to extend previous PATH work by developing traffic management models that recognize explicitly the ability of freeways to store vehicles, and to do this by only using the simplest ideas that have passed empirical tests.

Task Order 4117
Tom Golob, University of California, Irvine
tgolob@uci.edu
The objectives in this project are 1)quantify the relationships between the characteristics of freeway traffic flow and the likelihood of crashes per vehicle mile, by type and severity of crash, and 2) use these relationships to assess safety benefits that are likely to be realized under specific ATMS implementations. The research utilizes data from TASAS, in conjunction with both historical and real-time loop detector traffic data.
4. POOL FUND
STUDY - THE CONTINUATION OF MORIP

Robert Tam, PATH
rtam@uclink.berkeley.edu, www.path.berkeley.edu/PATH/General/Staff/rtam.html
This is a pooled fund project to study 1)
transportation performance measurements, 2) data sharing with the private
industry and 3) ITS hardware maintenance management. A four state (CA, MN, TX,
WA) working group has been established to share ideas and experiences in the
field of intelligent transportation systems. This project will develop white
papers to identify best practices and investigate new practices to implement.
5. DEVELOPMENT
AND EVALUATION OF ADAPTIVE RAMP METERING
MOU 3013
Michael Zhang, University of California, Davis
hmzhang@ucdavis.edu, http://www.engr.ucdavis.edu/~hmzhang
This project propose to evaluate a number of
off-the-shelf as well as new ramp metering algorithms using PARAMICS, identify
the most promising ramp metering algorithm and implement it in District 12 and
possibly in District 4. The project will document the findings of both
laboratory and field evaluation results and develop guidelines for ramp metering
implementation and operations at other locations.
