The Application...

• The rail traffic notifier system is used to inform the user of the status of grade level railroad crossings. This information may include a graphical map of the crossings in question, or textual information about any delays that the user may incur if they attempt to use a particular crossing.

The following are indications used in the graphical view of the system with their definitions:

• This indicates a track section that has no train occupying it.
• This indicates a track section that will soon be occupied by a train.
• This indicates that a train is currently occupying the track section.

Grade level crossings are clearly visible on the application map, where the grey roads cross a track sections. These track sections are identified with a crossing id.

This system is currently running under a simulator for demostration purposes.

In simulator mode:

• 1 true second is equal to one minute in the system
• Trains are set to run on 1 real minute cycles
  It takes 52 real seconds for the train to traverse the track sections visible on the screen
• There is an 8 second period once a train has left the last track section before the next train will begin to traverse the track
• The system is set to automatically refresh every 4 seconds.
• Addtionally, the following browsers are used to demostrate the adaptive properties of the system:
  • Microsoft Internet Explorer = Full desktop view
  • Netscape = In vehicle view
  • Mobile Phone = Handheld view (Any mobile phone browser identifying itself as a "MobilePhone" and can process HTML 4 code will work)
