• Caltrans (via PeMS.), for traffic information
• Incidents, from a web-based service (faked for this demo)
• Background maps through Google Maps

Demo Modes

The demo has two modes, representing two distinct types of users:

• "Consumer View", for everyday traveler access
• "Manager View", such as from a traffic operations center.

The button allows you to switch between them.

Additional simulated data appears on the Manager View:

• Shows location of emergency service vehicles
• Displays and allows editing of roadside Changeable Message Signs
• Displays intersection timing light information

Displayed Layers

Object Lists

The Manager can view all map objects in a list view, organized by information type. The list is kept synchronized with the map view.

You can select a line in the list and see the detailed information relative to the object.
