Development of Road Visibility Inspection System Using Driving Video Images Recorded by On-board Video Camera

In Hokkaido, Japan, every winter, road closures frequently occur due to blowing snow and snowdrifts created on roadways. Road inspectors are patrolling several times per day to monitor visibility state throughout winter. The real-time road visibility information that is collected by the road inspectors allows road maintenance managers to prevent accidents in winter and minimize the duration of road closures from blowing snow. The problem is that the inspectors boarding patrol vehicles report visibility [...]

Towards a More Resilient Spanish Road Network

Several studies state the increasing impacts related to weather in transport infrastructures, both related to extreme events and slow-onset processes. Road transport infrastructures are not an exception, finding that several road elements are becoming more vulnerable to climate change all over the world. Only in Spain, 45% of the main network and 4% of the total length is somehow impacted by climate [CEDEX, 2018], These impacts affect road’s safety and functionality; therefore, maintenance strategies [...]

Artificial intelligence Surface Temperature Prediction Model

In a mild climate where temperatures are often close to freezing, determining which parts of a road network should be salted on a given night is challenging. Accurate, granular forecasts of road conditions are needed to avoid unnecessary salting whilst maintaining safety. We present an Al road surface temperature prediction model trained using data from a network of 112 sensors across Kent in the Southeast of England. Using weather forecasts and location specific features (elevation, road type, [...]

Climate Resilience in the Road Sector in Mozambique

Mozambique is a coastal country constituted by a relief in the form of a stairway that decreases in altitude as we move from the interior to the coast. The hydrographic network is made up of rivers that run from West to East and nine of these originate in neighboring countries, this fact contributes to the record of frequent floods and/or floods in the lowlands.

Development of a Doctrine on the Use of Abrasives in France

Abrasives have been used for a long time and quite frequently for winter maintenance. However, the materials and practices used vary greatly and as things stand there are no reference document in France.
