RISM inspection

Province of Groningen

RISM uses a LiDAR camera which scans a road and its immediate surroundings. Based on the resulting 3D models, obstacles in the obstacle-free zone can be identified and removed where necessary.

Goal and impact

The aim of this algorithm is to make inspections for the purpose of road safety as efficient as possible. This has the desired result of increasing road safety and doing so as efficiently as possible with fewer obstacles for road users.

Considerations

Although the goal of this algorithm is to make inspections more efficient, interpreting the results is challenging. Choices have to be made in what is an obstacle and what is not.

Human intervention

The output of the algorithm reflects the facts. The output is interpreted and assessed by an expert from Royal HaskoningDHV, after which the expert forwards the findings to the Province in an advisory report. The Province itself then assesses whether, and where, any obstacles need to be removed.

Risk management

No automatic decisions are made by the algorithm, they are made only based on the advice of an expert. So there is a double verification of output here. Although number plates may be visible when video footage is taken, these are blurred by Geomaat. These images are not owned by the Province and the number plates present are not visible in the output obtained by the Province.

Operations

Data

The data used by the algorithm are LiDAR and camera images which together give a picture of the roads and the immediate surroundings.

Technical design

When a call for inspection is issued, cars with the necessary equipment are driven over the provincial roads to make recordings. These recordings are converted into detailed three-dimensional models of the roads and surrounding relevant areas. In these, the algorithm can recognise and mark obstacles within the obstacle-free zone. This output data is delivered to an expert from Royal HaskoningDHV. The expert evaluates the marked obstacles and delivers the findings in a report. The Province uses this report to intervene and remove obstacles if necessary.

  • Gladness reporting system

    Province of North Brabant

    The algorithm uses sensor data to make a calculation for predictions of slipperiness risks. These predictions are used to determine where to grit (preventively), in consultation with meteorologists. In addition, the algorithm can issue various alarms, for example when there is a chance of wet road sections freezing.

  • Road inspection - Kiwa KOAC

    Province of Groningen

    Inspection of provincial roads using LiDAR or laser technology. Using these techniques, the road section can be scanned in great detail and all unevenness highlighted. From this, the algorithm selects damage images on the basis of which the province will see what maintenance is needed here.
