Computer
Controlled Signal Systems
| The Situation |
Many of the signal systems within the Route 1
Study Area have fixed or preset timing and cannot dynamically respond to changes in
traffic flow movements or conditions, leading to excessive delays and/or queuing at
signalized intersections. |
|
|
| The Proposal |
Institute computer controlled signal systems
along selected roadways that can continually monitor traffic volumes and adjust signal
timings and phases accordingly. |
|
|
| The Locations |
Route 1 between I287 and 1&9 merge
(Edison, Woodbridge); Plainfield Avenue between Woodbridge Avenue and South Plainfield
Avenue (Woodbridge); Main Street/Rahway Avenue between Route 35 and Port Reading Avenue
(Woodbridge); Easton Avenue (New Brunswick); and, George Street between New Street and
Nichol Street (New Brunswick) |
|
|
| The Actions |
Conduct traffic counting programs/intersection
geometric surveys to develop base conditions and project to appropriate design year;
design signal systems; work with the appropriate agencies to have them incorporate base
elements of computer controlled signal systems (fiber optic conduit, loops) as part of any
roadway reconstruction projects; establish priorities for those systems recommended; then build. |
|
|
| Estimated Annual Cost ($Millions) |
$4-$6 (Total Capital Cost) |
|
|
| Overall Traffic Benefits |
High |
|
|
| Other Impacts and Considerations |
Computer controlled signal systems are
relatively new to New Jersey (one system is now in place on Route 18 from Old Bridge to
Piscataway). Because of the uniqueness and high levels of traffic in the State, this
strategy will not be pursued pending evaluation of the Route 18 system. |
