1. A bus comprising:
a vehicle body having a door opening;
a plurality of doors attached to the vehicle body to open and close the door opening;
a nosing seal disposed on one of the doors and a weather seal disposed on another of the doors, the nosing seal and weather seal mating together when the doors are closed;
at least one sensor disposed inside the weather seal, wherein the at least one sensor capacitively couples to an electrically conductive moving object proximal to the weather seal such that a capacitance of the at least one sensor changes;
a controller coupled to the at least one sensor, the controller analyzing the sensing by the at least one sensor and senses a non-smooth signal from the at least one sensor and determines that an obstruction is present, senses signal fluctuation from the at least one sensor is not monotonic and determines that the obstruction is present, senses that the one of the doors has not closed after a predetermined time period and determines that the obstruction is present, senses that one of the doors has stalled and determines that the obstruction is present, the controller being configured to alert an operator of the bus when the obstruction is present.
