Car Parking Counter Up To 99 Slots

Posted: 28 Mar 2011 04:09 AM PDT

hello every one.. i need some help and ideas here.. i have a project to make "car parking counter" for up to 99 slots.. the idea in its simplest form is to have a sensor in each parking slot, and two 7 segments displays common for all the slots.. so when a car enters the slot, the counter starts counting, and the display shows the number (01) which means that there is 1 full slot, and the rest are available..
i have the counters circuit but i need to konw how to conect it with the senser, to perform the wanted task??
