A travel plan target table that can be monitored

A travel plan targets table earns its place only if a council officer can pick it up in three years and tell, without asking anyone, whether the target was met. Most cannot. They carry aspirations such as "encourage cycling" or "reduce single occupancy car use", with no baseline, no date and no stated test, which makes the obligation unenforceable and the monitoring reports meaningless.

The fix is structural rather than editorial. Four columns, one row per target, and a survey method fixed in the document itself.

What makes a target measurable

A target works when three people reading it independently would agree on whether it has been met. That demands a single variable, a number, a date and a test.

Modal share is the usual variable, expressed as the percentage of person trips to and from the site by each mode in a defined period. Trip rate per dwelling or per 100 m² is the alternative where the authority has trip generation concerns rather than mode concerns. Either is measurable. Vague variables are not: "improved awareness of sustainable travel" cannot be surveyed in a way that survives scrutiny.

Three habits kill otherwise sensible targets:

• Targets that depend on somebody else. A bus frequency improvement is not within a developer's or occupier's control, so it cannot sit in the table as a target. It belongs in the measures list.
• Compound targets. "Reduce car driver mode share and increase cycling" is two targets and will be reported on selectively.
• Targets expressed against a baseline that was never measured. If the baseline is to be established by the first survey, say so in the table and set the target as a change from that first survey rather than from a guessed figure.

The four columns

Everything an officer needs fits in four columns, plus an objective column for context.

That table is illustrative. The percentage point changes in it are examples of how to express a target, not recommended values, and the right figures come from the trip generation work in the Transport Assessment for the site and from what the authority's own policies seek.

Two drafting points. Express mode shift in percentage points rather than as a percentage reduction, because "a 10 per cent reduction in car use" is ambiguous about whether it means ten points or a tenth of the existing share. And name the section of the travel plan that contains the survey method in the test column, so the method travels with the target.

Survey method and the response rate problem

The survey is the whole obligation. Get it wrong and every target becomes arguable.

Fix these in the document:

1. Population surveyed. All staff, all residents of occupied dwellings, or a defined sample with a stated sampling frame.
2. Question set. Reproduce it as an appendix. Changing wording between surveys destroys comparability.
3. Period covered. A single typical day is the common approach for workplaces, with a week-long diary where shift patterns vary.
4. Minimum response rate, with a stated remedy if it is not achieved.
5. Month of survey, excluding school holidays, August and the fortnight either side of Christmas.
6. Weighting. If response rates differ by occupier or by building, say how results are weighted.

A minimum response rate of 30 per cent of the surveyed population is a common ask from highway authorities for workplace plans, with a second wave of reminders where the first pass falls short. Set out what happens if it is still short: normally the survey is repeated the following year at the applicant's cost, and the target date moves with it. Without that, a low response rate becomes a reason the target cannot be assessed, and the obligation quietly dies.

Residential plans are harder. Response rates from private tenants are usually lower than from employees, so consider a doorstep or in-person element, and an incentive that the section 106 agreement permits.

Intervals, and the month that matters

Monitoring in years 1, 3 and 5 after a defined occupation trigger is the pattern most authorities accept for a medium scheme. Larger schemes with phased delivery need monitoring tied to each phase's occupation rather than to the permission date.

Define the trigger precisely. "First occupation" is ambiguous on a phased site. "The date on which 75 per cent of the dwellings in a phase are occupied, or 18 months after first occupation of that phase, whichever is earlier" is not. And state the survey month in the plan, because a June baseline compared against a February monitoring survey will show a cycling shift that has nothing to do with the plan.

Parking is often monitored alongside, and where the authority is concerned about overspill the survey method should follow the same methodology used for the baseline Parking Survey so that the two datasets are comparable.

Remedial measures tied to failure

A target without a consequence is a statement of hope. The mechanism that gives it teeth is a remedial measures schedule: a menu of additional interventions, each costed, from which the travel plan coordinator must select on a shortfall, within a capped total.

The capped sum is the negotiation. Authorities push for an uncapped obligation or a default payment per percentage point missed. Applicants want a fixed cap with the remedial menu as the only remedy. A workable landing point is usually a capped sum, indexed, with the menu drawn from measures already identified in the plan as second-tier options, such as an extended cycle mileage allowance, additional shower or locker provision, a car club bay, or a personalised travel planning exercise for new occupiers.

Write the sequence into the obligation:

1. Survey shows the target missed.
2. Coordinator submits a remedial statement within eight weeks, selecting measures from the schedule.
3. Authority approves or requires alternatives from the same schedule within a stated period.
4. Measures implemented within a stated period, with the next survey brought forward.

The same discipline that makes a schedule of viability appraisal inputs auditable applies here. Every figure that could later be argued about should have a defined source and a defined test.

Where the occupier is unknown

Speculative commercial floorspace and build to rent blocks present the obvious problem: nobody can commit to a modal share for an occupier who does not yet exist.

The answer is a two-stage document. A framework travel plan accompanies the application and sets objectives, the survey method, the monitoring intervals, the remedial menu and the cap. A full travel plan, produced by or with the occupier, is then required by condition or obligation before occupation, and it populates the target column using the framework's method.

Keep the framework's method binding. If the full plan is allowed to redesign the survey, the baseline comparison is lost. State plainly in the framework that the question set, survey month and response rate requirement are fixed, and that only the targets and measures are for the occupier to complete.

Where several occupiers share a site, a site-wide plan with occupier annexes usually works better than separate plans, because it keeps one baseline and one coordinator. The Travel Plan page sets out what the document as a whole needs to contain, and PlanScope can draft it structured to UK planning policy. Reports should be reviewed before submission, and we do not guarantee planning approval.
