    Write a function that calculates the combined traffic volume between consecutive monitoring points by adding adjacent sensor readings along a traffic corridor. The function should take a tuple of traffic volume measurements as input, where each value represents the number of vehicles detected at sequential monitoring points, and return the pairwise sums of neighboring measurements to help determine optimal traffic light timing patterns.
