CCIT is working to create an integrated testbed and data collection system, building on the Advanced Transportation Management System (ATMS) Testbed at the University of California, Irvine, and the Berkeley Highway Lab (BHL) at the University of California, Berkeley. The goal is to provide a unified point of access, via a Web interface, to an integrated traffic management system and a high fidelity data collection.

It can be used by California researchers and Caltrans practitioners to test traffic management strategies and conduct evaluations.

How does the proposed system work?

The project team is developing a user-friendly interface to be managed so that access is maximized without compromising functionality. By putting these databases under one access point, researchers and practitioners will have access to a rich array of data types, and the two facilities will be able to complement one another's efforts and eliminate duplication. When complete, the integrated facility will offer data from technologies that include: 30-second loops video cameras refreshing still pictures networks vehicle trajectories 60-Hz loops It will also have the capability of easily incorporating data from new technologies, such as wireless sensors, as they are developed.

How will it help?

Caltrans personnel and researchers at UC and elsewhere will be able to test out traffic sensing technologies by using the combined data, one of many opportunities for synergy between the ATMS Testbed and the BHL. Other areas that can be studied with the new integrated testbeds are:

• emissions projections for various traffic conditions
  
• travel time changes under different conditions
  
• traffic flow
  
• traffic simulations
  

The synergy between the ATMS Testbed and BHL can be seen in the table below, where the different types of data sets from each facility can be combined in different ways to study a range of problems.

Data		Application
Testbed	Type	Simulations	Emissions	Travel Time	Traffic Flow
UC ATMS	Network	x	x
	30-sec loop	x	x		x
	Advanced detectors		x	x
BHL	Vehicle trajectories	x	x	x	x
	60Hz loop	x	x	x	x

What is the role of CCIT?

This integrated testbed advances a core mission of CCIT, which is to promote collaboration among researchers and practitioners and provide testing grounds for transportation products and services in collaboration with industry partners.
