I am seeking ideas/processes/workflows on designing and implementing a real-time parking meter application that shows if a parking meter/spot is vacant or not.  And if not, how much time remains on the meter.  We have smart parking meters that provide a wireless stream of meter-related information.  The meter can sense the presence of a vehicle using RFID sensor technology.  I don't have any experience with GeoEvent Server, connectors and alike, but this seems like a reasonable starting point.  I envision a web map app that shows parking meter symbology in green, meaning no vehicle parked at that meter location (spot available), yellow, meaning a vehicle is parked at this meter location (spot occupied) but having less than or equal to 10 minutes of time remaining, and red, meaning a vehicle is parked at this meter location (spot occupied) with more than 10 minutes of time on the meter.  Or maybe I use 20 minutes as the break point.  I would like the app to have pop-ups illustrating meter information (hours, rates, ID, etc.).  I have been examining Esri's Public Parking solution which would provide a nice static solution, but I don't know how to take the idea to the real-time level.   I would like the application to include gate-controlled parking lots, which compare inbound gate openings to outbound, with the difference indicating available spots (or some similar "accounting" system).  Any input would be greatly appreciated.  Thank you in advance.
