What is it about?
Procedure to develop a route level reliability estimate for the system network when data are available only at the link level, which is typically the case because of how travel data are collected.

Why is it important?
There is always a necessity to derive a route-level reliability estimate of travel. However, travel time data are collected at the link-level which are shorter homogeneous segments of the roadway. Therefore, the link-level data need to be utilized to derive a route level reliability estimate. This paper researches this procedure and provides a potential solution.
Perspectives
Can help provide insights for further research in this area. Delineating a procedure for this critical step in conducting a transportation system's mobility and reliability performance is of high importance.
