Tasks involving road maintenance management are numerous and wide-ranging,including road inspection, recovery of dropped or abandoned objects, and identifying
and repairing road damage spots. Each of these tasks require its own work report tobe created, which can be time-consuming. A smartphone-assisted road patrol
assistance system can improve the efficiency of road maintenance management
operations.
Overview of the system
Easy portability and convenience of smartphones help collect on-site information and upload it to
the cloud for real-time information sharing, enabling speedy and organized response for
emergency repairs and other various situations.

Automatic report creation
Photos can be linked to the location mapthat show the patrol result. Damage spots
can be automatically summarized according
to the type and severity of the damage.
Repair-required location identification
Records of bumps and level differencescollected from daily patrol runs areautomatically summarized to identity

Bumps due to buried objects

repair-required locations, which arepresented on the location map together
with photos and damage description, thisgreatly facilitates road repair planning.
