Using smartphones as a very low-cost tool for road inventories

Higuera de Frutos, S. / Castro, M.

Highlights • Smartphone software tools have been developed for road inventories. • It provides a low-cost option for different types of roads. • This method is very useful in those instances in which a rapid response is critical. • GPS, camera and other smartphone sensors have been used.

Abstract Road inventories are a key component in the planning of road networks as they allow for efficient management and a better return on the investment. Current techniques for carrying out road inventories are expensive and entail long planning processes and data postprocessing. Furthermore, these inventories are only useful to those parties interested in designing and building road networks. This study presents a new method for create road inventories based on the use of the latest generation cellular phones, also called smartphones. This paper describes the use of several mobile apps developed for this project that were implemented during the different stages of road inventory process. The results indicate that the data processing speed, its low cost, and the ease of implementation from any type of vehicle validate the proposed procedure as an invaluable tool (1) to do inventories of all types of road networks that are not accessible to cars; (2) to manage the routine maintenance of small road networks; and (3) as a basis for future research projects on road design and outline.
