© Semel2006 GREEN BOX A GPRS based solution for; –Collect road charges –Surway Link speed –Collect and distribute FCD information –Piloted with Taxis Advantage of GPRS solution in Green Box –Low Data consumption (less than 1Mb/month/car) –Packed data –EMV level encryption –Heavy duty servers based on standard technology –On line solution

© Semel2006 GPRS RELIABILITY AND APPLICATION LEVELS GPRS application packed and iPSec encrypted Different message priority levels –Payment transaction 100 % by applications –Important broadcasts 3 times sent –Less important only one sending GPRS reliability figures –GSM/GPRS network loses app. 2% of messages –Testfigure of 2 weeks (as example); Sent messages Two resets, meaning loss of network contact Coverage practically 100%

© Semel2006 GPRS NETWORK RELIABILITY AND COVERAGE Example of –New Initialisation into GPRS network –Coverage during 2 weeks test

© Semel2006 SUMMARY GPRS is suitable for online FCD gathering, and distribution, but needs tailored solution GPRS coverage is very good Data consumption can be handeled by using Green Box type zone solutions Project will end in September, and then there will be data from Green Box cars to compare with roadside FCD cameras.
