Abstract

In traffic engineering, a lot of valuable information is obtained after appropriate processing of data collected by certain sensors. However good the data may be, the information extracted can be completely wrong if the processing is inadequate. One of the most common simplifications in the field, which, for example, affects some travel time estimation methodologies, is the use of temporal average speeds as equivalent to spatial averages. This chapter explains the causes of this bad practice, which is linked to the most traditional (and most extended) road equipment and procedures. To correct this trend, a highly applicable solution in the form of an algorithm is proposed. Although the results of the algorithm are not fully robust, they are favorable in a wide variety of cases, with the added bonus that no additional investment would be required.
