Traffic engineers also evaluate the traffic flow along a roadway using a “time-space” diagram. This two-dimensional diagram shows the position and travel path of a vehicle through time as it moves from one intersection to another. The diagram shows multiple intersections along a corridor and provides detailed operation of each intersection as to when green, yellow and red times will occur.
In deciding if a traffic signal will be an asset instead of a liability, Traffic Engineers evaluate nationally accepted warrants for traffic signals, both part of the State of California Traffic Manual and the Federal Manual on Uniform Traffic Control Devices. The installation of a traffic signal should be considered if one or more of the warrants in the referenced manuals are met including:
Minimum Vehicular Volumes
Is the volume of vehicles entering an intersection creating confusion or congestion?
Traffic signals are more costly than is commonly realized, even though they represent a sound public investment when justified. The major components associated with the installation of a traffic signal are as follows:
What is the difference between Solar Photovoltaic (PV) and Solar Hot Water Systems?
Solar Photovoltaic (PV) systems convert sunlight into electricity which can then be used to power appliances in the home or be sold back to the grid.
Homeowners and Businesses which install solar energy systems may be eligible for a variety of rebates, incentives, and tax credits.
Rebates & Incentives
Rebates for PG&E and for SCE customers have been exhausted and the program is closed.
These programs are administered through Southern California Edison (our local power utility) in conjunction the State of California (Go Solar California Program).
