We match the passenger's time window with the driver's time at the pick-up point:
The driver just enter when you will depart at your start point. As a passenger you need to be a little bit more flexible: enter a time window defined by the earliest start time and the latest start time at which you'd like to be picked up at your pick-up point.
The system will match the times at which the driver passes by at the passengers pick-up point. If the driver's pass-by time is within the passenger's time window, the passenger will receive a text message with the name and phone number of the driver and the time of the potential match. As a passenger you should then call the driver to arrange the pick-up.
