Road Safety Assessment

road safety assessment

The road safety assessment by ASACERT is carried out in accordance with the Guideline of the Legislative Decree 35/2011 – ” Road infrastructure safety management” – following the process and criteria indicated to carry out security inspections in the existing infrastructures.

ASACERT professionals conduct the road safety assessment following the periodic inspection programme established by the competent Authority in accordance with the art. 6 of the above mentioned Decree, which is updated every two years in order to guarantee adequate levels of safety.


The main purposes of the road safety assessment are:

the identification of the road infrastructure’s critical issues directly related to incidental events

the identification of potential risk factors of the road infrastructure, which could give rise to sections with a high number of accidents

the identification of the priority of the infrastructural remedial interventions both to reduce the number and the seriousness of accidents and to prevent further others

monitoring the road network safety status

The inspection team specifically constituted by ASACERT carries an analysis which terminates with a final report.

The final report clarifies, as result of the inspection, if there is any critical issue to fix or if management or infrastructural provisions are needed in order to improve the safety of the considered road segment.


This kind of inspection is conducted through the following phases:

The road safety assessment is preceded by a meeting with the Competent and the Managing bodies, which must provide to ASACERT – according to the provisions of art. 7, C. 1 of the Legislative Decree 35/2011 – information on the conditions of use of the road section and all preliminary data currently available, such as:

  • Cartographies
  • Recently executed or forthcoming interventions
  • Traffic data
  • Analysis of incidents and eventual reports of accident

Detailed procedures for accessing and inspecting the infrastructure section are also defined and agreed with the Managing body.

The inspection is carried out covering the road segment in both directions of travel in different ways, varying depending on the type and characteristics of the infrastructure. During the course of the inspection the road section pictures are taken and videos are shooted, with the support of the Managing Body, using a vehicle equipped with appropriate technological systems in order to guarantee the georeferentiation of the collected data.

ASACERT inspectors fill out the inspection form as specified in par. 4.3.2 of the guidelines of Legislative Decree 35/2011 and write an inspection report including also the data of the elements assessed but not mentioned in the form. There is a form for each type of road, and report different data that depend on the assessment methods and kinds, which mainly consist of:

  • Diffused inspections of the entire homogeneous road segment, conducted during the day and at night. This type of assessment includes two phases: a first preliminary phase aimed at comprehending the general issues and the characteristics of the road section in relation to the entire network, morphology and usage of the territory, and a general phase to deeply analyse the safety problems distributed along the road.
  • Punctual detail inspections, diurnal and nocturnal, of individual critical sites where a considerable number of accidents occurred in proportion to the traffic flow or potentially critical and of singular spots of the track intended as intersections and other important interferences (tunnels, viaducts, etc.).

At the end of the documental and on-site analysis, ASACERT team prepares a final report containing any issues, concentrated and diffused, observed in the entire road segment and the relative degree of seriousness, as well as the identification of one or more possible applicable solutions.

The final report will be divided into:

  • Requirements: solutions to serious deficiencies related to primary design and management regulations lacks; these solutions shall be adopted and transposed by the Managing Body on specific request of the Competent Authority
  • Recommendations: solutions that effectively contribute to improve the safety status and require a joint planning between the Managing and the Competent Bodies
  • Indications: suggestions that the Managing Body can easily implement
