The Ministry of Transport employed technology in the survey and assessment of roads and bridges

The Ministry of Transport has employed technology in the survey and assessment of 154 thousand km of roads and 4.7 thousand bridges.  

The Ministry of Transport revealed the completion of a survey. In this survey more than 154 thousand kilometers of road tracks and more than 4700 bridges were assessed in order to measure their quality and to observe any damage affecting the road users, as well as to identify the future state and the maintenance needed to maintain the level of performance and safety by using modern laser and scanning equipment.

The Ministry of Transport conducts this survey every year for the evaluation of its roads and every three years for bridges. This survey is a part of an implementation of a well thought out strategy to provide a world-class road network and an integrated, advanced infrastructure in accordance with Vision 2030, which will contribute to raising the efficiency and quality of roads to provide the best services to citizens by improving road safety levels, facilitating vehicular traffic and smooth traffic.

The aim of this survey and evaluation process is to update the basic map, diagnoses of the road infrastructure, identifying damage to it and maintaining it by using modern techniques and advanced methods.

The ministry will also carry out the 90,000 km panoramic project of the Kingdom’s roads to enable survey and evaluation for officials to observe the roads on the ground by allowing them to simulate road driving as if they were actually using it. Allowing them to measure the different dimensions of road elements, and to determine its maintenance requirements.

In terms of the achievements of road survey and assessment, Riyadh region topped the Kingdom’s lengths in the surveyed and evaluated roads. Riyadh’s roads were 36,000 kilometers long, followed by the Eastern Province by more than 20,000 kilometers, Makkah area with lengths exceeding 17,000 kilometers. The length of the roads surveyed and evaluated in the Hail area was 10.5 thousand kilometers, and the 10,000 kilometers in the regions of Asir and Tabuk, and 6,000 kilometers in the regions of Al-Jawf and the northern border, and 5,000 kilometers in Najran, and 3,000 kilometers in the regions of Jazan.

As for the survey and evaluation of the bridges, the Riyadh region also topped the Kingdom. The number of bridges surveyed was 950, followed by Makkah with 832 bridges, Madina with 668 bridges, Asir with 531 bridges, Qassim with 354 bridges and Sharqia with 312 bridges, Hail with 236 bridges, Jazan with 235 bridges, Tabuk with 205 bridges, Bahah with 187 bridges, Jawf with 114 bridges, Najran with 82 bridges and 37 northern bridges.

The Ministry uses five advanced technologies in surveying and evaluating roads. The first method measures the damage to asphalt surfaces, and the second measure the global roughness factor and the comfort of motorists. The third method measures the deviation in the pavement layers, while the fourth measures the paving thickness, and the fifth measures the resistance of slipping.

There were specialized teams applying the latest versions of the global system of assessment of bridges, performing the necessary tests on the different elements of bridges and facilities using the latest equipment and provides the specialized technical reports for each bridge showing the damage and methods of technical treatment and quantification. The necessary repairs are in accordance with the various operation and maintenance contracts in the Kingdom. The automated monitoring of the most important bridges in the Kingdom is carried out according to the latest systems used in the world.

Among the survey and evaluation projects carried out by the Ministry is the Mobile Digital Imaging Project, which enables the periodic maintenance of the non-paper elements of all road contracts to be carried out in the GIS database.

The digital imaging survey system is one of the most advanced and accurate systems in the survey and monitoring of elements on the road network in the Kingdom with guidance signs and warning, the measurement and monitoring of lighting poles, and the ability to measure the various dimensions and lengths of roads, through which three-dimensional digital images and field with a full view up to 360 degrees can be produced.
