S30041 Shunt Module Development

Project Objectives

• Improve the representativeness, accuracy and credibility of iRAP model use on the SRN by including the shunt crash type.
• Better understand how shunt collisions are initiated, what influences their severity, and what measures we can take to reduce their number and severity.

We will achieve this by

2025/2026

• Undertaking a review of previous work and undertake scoping review to inform modelling options
• Select and prepare suitable data ready for modelling.
• Undertake modelling to produce crash modification factors (CMFs)

2026/2027

• Use the outcomes from WP3 to create a shunt crash type within the iRAP model testbed
• Undertake shunt crash type validation to ensure the shunt crash type works for other road networks as well as the SRN
• Present findings, including the shunt crash type development work and the validation work, to iRAP Global Technical Committee.
