    Calculate the combined passenger load between consecutive bus stops by finding the sum of passengers at each pair of adjacent stops along a bus route. Given a tuple containing passenger counts at each stop, determine the pairwise sum of adjacent stops to help optimize bus capacity and scheduling decisions.
