  Advancements in Intelligent Transportation System (IES) improve passenger
traveling by providing information systems for bus arrival time and counting
the number of passengers and buses in cities. Passengers still face bus waiting
and seat unavailability issues which have adverse effects on traffic management
and controlling authority. We propose a Face Detection based Framework (FDF) to
determine passenger seat availability in a camera-equipped bus through face
detection which is based on background subtraction to count empty, filled, and
total seats. FDF has an integrated smartphone Passenger Application (PA) to
identify the nearest bus stop. We evaluate FDF in a live test environment and
results show that it gives 90% accuracy. We believe our results have the
potential to address traffic management concerns and assist passengers to save
their valuable time
