Objectives:

To review the standard for skidding resistance in HD28 Design Manual for Roads, and undertake an RTI analysis of the UK road network.

Methodology:

A network level analysis of the influence of skid resistance on RTI risk was carried out using existing databases of information. This included 29,250 RTI records.

Key Findings:

  • New investigatory levels have been proposed. In most cases, this includes a range of investigatory levels for each site category.

  • This range of risk emphasises the need for the reaction to low skidding resistance to be based on investigation rather than automatic intervention.

  • As well as helping to meet RTI reduction targets, it appeared that the cost of the changes would be covered in the savings associated with the RTIs reductions.

Themes:

Skid resistance, RTI reduction
