Kathmandu road division launches an app to report road damage

What happened

Road Division Kathmandu works under the federal infrastructure ministry. It launched Sadak Sujhav, which means road suggestion, after a trial period. The app is on the Google Play Store for Android phones and the Apple App Store for iPhones, according to Ratopati English. Before the formal launch, Division Chief Engineer Subodh Kumar Devkota showed it to the members of parliament elected from all 10 constituencies of Kathmandu district.

Users can report potholes, damaged or sunken roads, waterlogging, broken footpaths and road dividers, zebra crossings, and other road safety or construction problems, The Himalayan Times reported. A user taps a button to report a problem and uploads a photo. The app reads the place where the photo was taken. If that fails, the user can search for an address instead. Each report also needs the type of problem, how severe it is, and a nearby landmark.

After a report is sent, the user gets a reference number. The status of the report can be followed inside the app, and the user receives a notice once the problem is handled. The division says it assesses each report by need, severity and priority before it acts. When a road is not part of the federal network, the app tells the user which agency is responsible for it.

The engineering behind it

Ratopati English says the app uses a geographic information system (GIS) to pin each problem on a map. In general, a phone with GPS can store the latitude and longitude of a photo inside the image file. An app can read those numbers and turn a photo into a point on a map. A GIS then keeps each point together with its details, such as the problem type and severity. This lets engineers see where problems cluster on a road.

Telling a user which agency owns a road is a common GIS task. The system needs a map layer of every road, tagged with the office responsible for it. When a report arrives, software finds the nearest road segment to the reported point and reads its owner. The quality of this answer depends on how accurate and current the road layer is. A wrong boundary sends a complaint to the wrong office.

The reference number and status tracking work like a ticket system. In a typical design, each report is a record in a database that moves through states such as received, assessed, in progress and resolved. Each change can trigger a notice to the user. The same records can later show how long repairs take and which roads produce the most complaints. That history is useful for planning maintenance budgets.

Severity and landmark fields help with triage. A deep pothole on a busy road needs action before a cracked footpath on a quiet lane. Asking the user to rate severity gives a first guess, but engineers still need to check the site. The landmark helps a repair crew find the exact spot when the GPS reading is a few metres off, which is common near tall buildings. Systems of this kind also have to deal with duplicates. When many people photograph the same pothole, a good design groups the reports into one job and counts them, so that a busy spot rises up the list instead of filling it.

What it means in Nepal

The app is part of a wider repair effort in the valley. The Himalayan Times reported that the division has stepped up road repairs and earlier sent out a pothole repair vehicle, which it calls a road pothole repair ambulance, to fix potholes quickly. The app gives that crew a steady list of reported problems, with photos and locations, instead of waiting for complaints by phone or in person. The photos also give engineers a record of the damage before anyone visits the site.

At the launch, one suggestion was to involve riders and volunteers, who could find potholes on a regular schedule and report them through the app. The division expects the system to improve how road problems are reported, monitored and ranked, and to make repairs more open to the public. Devkota described the aim as making it quick for people to report problems on federal roads.

The launch reports said Lalitpur and Bhaktapur would be added within about two weeks, followed by gradual expansion across the country. The sources do not give the number of reports received or repaired so far. That data will decide whether the app is useful. A complaint app helps only if reports lead to repairs, and if the public can see that they do.
