"The Passenger advisory signs will be the issue which causes the most problems on this project."
Was it a self fulfilling prophecy? I don't believe so. Read on and let the facts help you decide.
Things to consider when installing an electric sign in a public place.
1: Power?
-
Is there any?
-
How far away?
-
Who will pay the bill?
-
Do we have to dig,
-
Is it safe?
2: Appearance
-
Visibility
-
Day light
-
Night time
-
Distraction
-
Disturbance
3: Local jurisdiction
4:Risks
5: Ongoing troubleshooting and maintenance plans.
How does the information delivered to the passenger get to the sign?
-
Vehicle receives a GPS location from Satellite.
-
Every 15-30 seconds this location information is sent to a server via the internet via the Cellular phone network. Other bits of information are also sent to the server.
-
Programs on the server store the information and begin the processing.
-
A prediction is calculated and the server then sends a prediction to the Sign controller.
-
The predictions are displayed to the passenger.
Seems simple eh? Well just wait until you see how many ways they got it wrong.
