Following the same theory previously presented at the JCT Symposium on the RARR (Route Analysis Recommendation Report) process, this presentation/paper investigates the use of traffic signal technology and targeted timing adjustments to improve journey times and reliability for prison vehicle movements between courts and custodial establishments. Using detailed route and performance data, key prison priority routes were analysed and optimised to provide more efficient progression through the road network while maintaining overall traffic stability. The initial results demonstrate clear potential to support safer, more predictable and more efficient justice transport operations. The findings have provided a strong evidence base for developing a policy-led approach to prioritised prison transport movements and for expanding the initiative to further routes in future phases.
