FOURTH DIMENSION TRAFFIC

Company Summary:

Fourth Dimension Traffic was founded in 2003 in San Francisco, CA.  Fourth Dimension's primary product is the "D4" Traffic Signal Software package for Type 2070 ATCs.  The "D4" debuted right here in San Francisco at the corner of 3rd and King Streets (where AT&T Ball Park is located, Home of the San Francisco Giants). 

As of April, 2009, approximately 400 "D4s" have been deployed in the City of San Francisco, a city with approximately 1200 signalized intersections.  The City is involved in a 10+ year project to convert all traffic signal controllers over to 2070 ATCs running the "D4".  As part of this project, a state of the art transportation management center has been constructed at the City of San Francisco Traffic Engineering offices.  Currently, approximately 100 “D4” intersections are managed using Telvent’s MIST management software.

The "D4" specializes in easily configurable advanced actuated signal control and transit signal control (including one of a kind cable car priority / preemption).  The "D4" has a unique combination of features for optimizing fixed time or actuated control under both coordinated and free operations.

Fourth Dimension Traffic also offers traffic signal integration and training as well as other traffic engineering services.
