Pope of LNMS M18 J1 signals Highways Agency

This document describes an evaluation of the M18 Junction 1 Traffic Signals Local Network Management Scheme, which was implemented to alleviate congestion, delays, and enhance safety by introducing new traffic signals and road improvements. The evaluation, conducted by Atkins Limited for the Highways Agency, utilized traffic data, journey time analysis, accident statistics, and stakeholder feedback. Although the scheme resulted in longer overall journey times, particularly on the A631 West approach, it significantly reduced accident rates and eliminated serious or fatal accidents. Economically, the scheme's First Year Rate of Return and Benefit Cost Ratio were lower than anticipated, but long-term projections suggest success. The scheme also had positive impacts on journey quality and physical activity, with minimal or no negative effects on the environment or security. Recommendations for future projects include considering varied time periods for journey time benefits and exploring part-time signal operation. Despite mixed journey time results, the scheme's substantial reduction in accidents deems it successful. **This summary was written by an AI model and therefore should not be considered a definitive summary of the report.
