Highways mitigation per trip-end
Junction-improvement and signal-upgrade contributions are costed per peak-hour trip end generated by the scheme. National Highways typically requests contributions for SRN junction works; local highways authorities request for non-strategic junctions. Both must pass the reg 122 necessity test [CIL Regs 2010 reg 122].
Bus-service revenue subsidy
Where a new or enhanced bus service is required, the LPA negotiates a revenue subsidy over a defined period (typically 3 to 5 years) on the basis that fare-box revenue will be insufficient until ridership ramps. The subsidy is payable in tranches on commencement and on occupation milestones.
Active travel
Cycle lane extensions, pedestrian crossings, controlled junction treatments and bus-stop upgrades are typically delivered via a works clause in the deed rather than a cash contribution. The works estimate feeds the residual viability appraisal.
Travel-plan monitoring fee
A travel-plan monitoring fee, typically £1,500 to £3,000 per year over 5 years, sits in the deed under the transport head rather than the monitoring fee head. It funds officer time to track modal-shift targets and trigger corrective actions if targets are missed.
