Residential and workplace travel plans compared

Asking whether you need a residential travel plan or workplace travel plan is really asking who will be there to implement it. A residential plan targets households who have not moved in yet and is delivered by a management company for years after the developer has gone. A workplace plan targets a known workforce and is delivered by the employer, who can survey them, incentivise them and change their car parking allocation next month. Same document title, different instrument.

Getting the choice wrong at scoping produces a plan with targets nobody can influence and monitoring nobody will fund.

What each plan is trying to change

A workplace plan is about the commute. The trips are repeated, the arrival and departure times are concentrated, and the destination is fixed, so the measures act on a predictable pattern. Reducing single-occupancy car commuting by a stated percentage is a meaningful target, because the employer controls the car park.

A residential plan is about household travel across all purposes: commuting, the school run, shopping, leisure. The trips are dispersed in time and direction, and nobody controls the household's car ownership decision except the household. The practical lever is the set of choices available at the moment people move in, which is why a residential plan that arrives after first occupation has already lost most of its effect.

That difference drives everything else in the comparison.

Who implements each and for how long

On a residential scheme the developer writes the plan, appoints a coordinator for the construction and early occupation period, and then hands over. The handover is where residential plans die. Unless the obligation names the successor, funds the coordinator role and gives the management company a duty in its own documents, the plan becomes a PDF on the authority's website.

So write the handover into the document: who holds the role after the last unit sells, where the money comes from, and what the management company's service charge covers. An authority that sees that will accept a shorter monitoring period than one that does not.

On a workplace scheme the occupier is the implementer and the difficulty is different. The applicant is often a developer building speculatively, with no occupier identified. The answer there is a framework plan that binds whoever takes the building, with the full plan submitted once the occupier is known.

The baseline problem

A workplace plan can start from a survey. You can ask 200 staff how they travel, when they arrive, where they live and what would change their behaviour, and the resulting mode share is the baseline against which everything is measured. It is real data about real people.

A residential plan cannot do that, and the honest approach is to say which proxy you have used. Census travel to work data for the relevant output areas gives a defensible starting mode share for journeys to work, though it says nothing about other trip purposes. Trip rates from the industry trip rate database, filtered to sites that are actually comparable, give trip generation but not mode choice. Comparable recently-occupied schemes in the same authority can give both, if the authority has monitoring data and will share it.

Whichever you use, state the source and its limits in the Travel Plan itself. A plan with an unsourced baseline invites a highway authority objection, and the objection is usually right.

Measures that work in each setting

The two lists overlap less than people assume.

Residential measures that earn their place:

• Cycle parking that is secure, covered, at ground level and closer to the front door than the car, sized and laid out to the standards in Cycle Infrastructure Design guidance rather than to a bare numerical minimum.
• A car club bay with membership included for the first year or two, which works where there is enough density to sustain it and fails on small peripheral sites.
• Travel information provided at the point of sale or letting, not six months later.
• Electric vehicle charging provision, which is now largely driven by building regulations rather than the travel plan, as our note on electric vehicle charging in new residential development sets out.
• Parking supply set deliberately, because the number of spaces influences car ownership more than any leaflet.

Workplace measures that earn their place:

• Car parking management: permits, charging, allocation by need rather than by grade, and reallocation of spaces to car sharing.
• Season ticket loans and salary sacrifice cycle schemes.
• Showers, lockers and drying space, without which wet-weather cycling does not happen.
• Flexible and remote working policies, which shift the peak as effectively as anything physical.
• A named coordinator with time allocated, which is the single best predictor of whether a workplace plan does anything.

Framework plans and the full plan that follows

A framework travel plan is the right instrument where the end user is unknown or the site is phased over years. It sets the principles, the target mode shares, the monitoring regime and the mechanism, and it commits future occupiers to producing a full plan within a stated period of occupation.

Three things make a framework plan work rather than defer the problem:

1. Targets expressed so that they can be measured against a baseline that will exist later, rather than against data nobody will collect.
2. A trigger tied to something observable, such as occupation of a stated proportion of floorspace or the first anniversary of occupation of each phase.
3. A default mechanism, so that failing to produce the full plan has a consequence.

On a large mixed scheme you may need both types running in parallel, with a residential framework covering the housing phases and a workplace framework covering the commercial floorspace, each with its own coordinator and its own monitoring cycle.

Securing each through obligations

A travel plan is normally secured by a section 106 obligation rather than by condition, because the obligation can bind successors in title, fund monitoring and create default payments. Conditions can require submission and approval of a plan before occupation, which is enough on a small scheme but cannot compel a management company to keep doing anything in year four.

The mechanics of the contributions and monitoring fees are covered in our piece on travel plan contributions and monitoring fees in section 106. Two drafting points are worth flagging here. Default payments should be tied to a measurable failure, not to a subjective judgement about effort. And the monitoring survey methodology should be specified in the obligation, because a dispute in year three about whether a survey was valid is an expensive way to discover that the wording was loose.

Choosing the type at scoping

Settle this in the pre-application transport scoping discussion, alongside the scope of the Transport Assessment or transport statement, and get the answer in writing.

Ask the highway authority four questions. Which plan type it expects for this use and scale. What monitoring period and survey frequency it applies as standard. Whether it has a published travel plan guidance note or template, because many authorities do and using theirs saves a revision. And what it will accept as a baseline for a residential scheme in that area.

On major applications of 150 or more dwellings, and at the floorspace and site area thresholds that apply to other uses, Active Travel England is a statutory consultee, and its interest is in the quality of walking and cycling provision rather than in the travel plan document. Designing to the cycle infrastructure guidance from the outset avoids a late objection that the travel plan cannot cure.

One honest uncertainty. Evidence that travel plans change behaviour at the scale their targets claim is mixed, and the measures most likely to work are the physical and financial ones rather than the promotional ones. Write the plan accordingly, and put the money into parking management, cycle storage and a funded coordinator rather than into printed material.

This is general guidance, not legal advice. Check the position with your local planning authority and highway authority, or a qualified transport planner, before relying on it. Councils usually expect a travel plan to be prepared by a suitably qualified author, and professional review is strongly advised.
