Traffic sign plans with AI

Traffic sign plans
become geodata.

Our AI reads traffic sign plans from PDF and turns them into geodata: work zones, closed lanes, traffic signs, periods.

Applications for traffic orders arrive as PDF drawings. For coordination and traffic information, somebody redraws the area by hand. Replan proposes the objects and places them on the map. The case officer checks, corrects and confirms them in a review app.

How it works

From PDF to geodata layer.

Computer vision finds signs and areas in the plan, a language model reads place, period and works from the application. Both land on the street network.

Process

From PDF to geodatabase.

01

PDF

The plan comes from the application portal or the specialist system.

02

Detection

Traffic signs, work zones, closed lanes, legend, period and street reference.

03

Review

The case officer confirms or corrects. Uncertain objects come first, with confidence.

04

Geodata

Export as GeoJSON to GIS, roadworks coordination and traffic information.

Features

What the review app does.

Detect signs

Traffic signs in the plan are detected and taken over with position and type.

Place areas

Work zones and closed lanes appear as areas on the map, linked to the street.

Read periods

Start, end and closure times from plan and application are attached to the works.

Review and confirm

Plan and proposal lie on top of each other. Every change by the case officer is saved.

Hand over

GeoJSON for GIS and specialist systems. Other formats or an interface we agree with you.

Coordinate

The captured works go straight into the compatibility check. Roadworks coordination

Questions and answers

Frequently asked questions.

What is a traffic sign plan?

A traffic sign plan shows how roadworks or an event are secured on the street: work zone, lanes, traffic signs and barriers. In Germany it is part of the application for a traffic order (verkehrsrechtliche Anordnung).

How accurate is the detection?

In the Berlin pilot the model detects traffic signs with 96 % precision and 82 % recall, trained on 113,190 images. The case officer confirms every result before it goes into the geodata.

Does the AI decide on the traffic order?

No. The AI makes proposals, the case officer checks and confirms. The order stays with the authority.

Which formats come out?

GeoJSON with work zones, closed lanes, traffic signs and periods. Other formats or an interface to your specialist system we agree with you.

What happens to the geodata next?

It goes into roadworks coordination: Replan checks every works against all others and simulates whom a combination of closures affects. Roadworks coordination with Replan →
