bool	at_near_stop (const blocked_lane_data_t &blk_lane_, unsigned &int_id_, unsigned &stop_wp_id_)
	Returns true and sets int_id_, if blk_lane is on a stop waypoint, else return false.
void	update_stop_point (const blocked_lane_data_t &blk_lanes_, unsigned int_id_, unsigned stop_wp_id_)
	Updates the intersection_status [int_id_] for the blk detected. If its a new blockage then all parameters are set, if its old blockage then only 'm_last_noticed' time is updated.
void	flush_old_blockage (intersection_status_t *it_st_)
