A couple users of the system have been identified. First, emergency dispatch centers are equiped with full size monitors capable of displaying the most information visually to the user. The dispatcher will be able to see the current mapped crossings, and color coded track indications. Additionally, these users will be provided with estimated delay times and estimated time until block. This type of use will usually be working autonomously. Additionally, it is more likely that the computer they are using has access to a high speed network connection, and therefore will be provided with periodic updates in addition to on-demand updates of the system state. This type of user will not want to have an audio announcement of the information as they are often in communication with several individuals at one time. These users can be expected to simply glance at the screen to get the latest information and provide their suggested course to emergency vehicles and personnel that either are not equiped with the hardware to access the system or are not in a situation to use that hardware.

The second type of user identified is one with hardware mounted in their vehicle, such as the computers mounted in police cars. The media will need to be adapted to the hardware and situations that these users may find themselves. The hardware in police cars would be much smaller than a normal sized computer monitor, so the graphics need to be adapted for this smaller screen. The visual cues of the map would be advantageous to a police officer as they could quickly assess if there is a train approaching a crossing while chasing a suspect. Additionally, they will be provided with numerical output of estimated delays and estimated time until blocks on crossings for the situation that they have a partner with them who then can navigate the driver towards an unblocked crossing. A future enhancement to the system may include an audio announcement of the delays and block times for crossings displayed on the map. This would enable the driver, if alone, to keep his or her eye on the road rather than reading a screen. Firefighters are another type of user that falls into this category. They could use this system in the same manner as the police, of course their goal is a bit different. Again, in this adaptation the system would periodically update in order to keep the officers up to date on the status of the system.
