When a campus fences off a 600-space lot for a garage repair or a new building, those 600 cars do not disappear. They move. Some go to the replacement lot across campus, some circle the remaining close-in lots at 8:10 a.m., some park in the neighborhood and annoy the neighbors, and a few people quietly start arriving late to their first class or meeting. The temporary shuttle service you put between the replacement lot and the core of campus is what decides which of those outcomes you get.
This guide is for parking and transportation managers, facilities project leads and business officers who have just been told a lot or garage is closing for weeks or months. It follows the project from start to finish: sizing the displacement, designing the service, contracting it, announcing it, running it day to day and winding it down when the fences come off. It is about daily commuters (faculty, staff and commuter students), not a one-weekend event, so the numbers are built around a repeating weekday pattern.
What other campuses have done
Real closures are a useful starting point. When Princeton closed its Theater Drive Garage for summer repairs in 2023, the university published a closure notice that matched displaced parkers to alternate garages by where on campus they worked, pointed them to existing TigerTransit routes running every 5 to 10 minutes in the morning, and reopened the garage in phases.
At a smaller scale, the University of Alabama in Huntsville restricted Lot G9 during a 2022 construction phase and ran a shuttle from Lot W28 Monday through Thursday, 10 a.m. to 2 p.m., about every 15 minutes, with named boarding points in each lot. A temporary shuttle does not have to run all day to be useful.
Sometimes no shuttle is needed. Purdue’s 2024 Grant Street garage closure notice simply sent permit holders to another garage. If the replacement lot is a short walk away, a good map may be enough. The rest of this guide assumes it is far enough that people will not walk it in January.
Phase 1: Size the displacement before you size the fleet
The most common mistake is quoting a shuttle based on the number of spaces closing. Spaces are not riders. Some displaced parkers will switch to a carpool or public transit (our comparison of employee shuttles and carpooling covers that trade-off), and the rest will arrive on a curve. You need three pieces of information, and your parking office probably has all of them.
Who actually parked there
Pull the permit data for the closing lot. Faculty and staff permits behave differently from commuter student permits. Staff tend to arrive in a tight morning band and leave in a tight afternoon band. Commuter students arrive in waves tied to class start times and may come and go more than once a day. Night-class permits, reserved spaces and departmental vehicles each need their own answer. If gate or license plate data exists, use it to see how many permit holders actually show up on a typical Tuesday, which is almost always fewer than the permits sold.
When they arrive
The shuttle has to be sized for its busiest 30 minutes, not for the daily total. Gate counts in 15-minute bins are ideal. If you do not have them, count cars at the lot entrance on three weekdays before the closure, ideally a Monday, a Tuesday and a Thursday, in 15-minute slices from 6:30 to 10:00 a.m. That arrival curve is the single most useful number in the whole project.
Where they are being sent
Measure the replacement lot to the drop-off point by actual driving route, at the actual morning hour. Note the signals, the crosswalks that flood at class change and any gate or turn a bus will struggle with. Then decide where the shuttle drops off. One central stop is simpler to run; two stops cover more of campus but lengthen the loop. Our guide to planning employee shuttle routes walks through choosing stops when riders are headed to several buildings.
Worked example: 600 displaced permits
Here is a hypothetical example with round numbers, so you can follow the math and swap in your own figures.
- The closing lot holds 600 permits, mostly staff and commuter students.
- Gate data shows roughly 70% of permit holders park on a typical weekday, so about 420 cars a day.
- The morning peak runs 7:30 to 9:00 a.m., and about 60% of the day’s arrivals land inside it, roughly 250 people.
- The busiest half hour, 8:00 to 8:30, carries about 100 of those people. That is a rate of 200 riders per hour.
- The drive from the replacement lot to the central stop takes 9 minutes one way in morning traffic.
| Step | Calculation | Result |
|---|---|---|
| Running time, round trip | 9 min out + 9 min back | 18 min |
| Loading and unloading | About 2 min at each end | 4 min |
| Recovery buffer | Slack for a missed light or slow boarding | 3 min |
| Cycle time | 18 + 4 + 3 | 25 min |
| Planning load per trip | 30-seat vehicle planned at about 25 riders | 25 riders |
| Trips needed in peak hour | 200 riders per hour / 25 per trip | 8 trips per hour |
| Headway | 60 min / 8 trips | About 7.5 min |
| Vehicles in service | 25 min cycle / 7.5 min headway = 3.3, round up | 4 vehicles |
| Spare | Standby for breakdowns and the first-week surge | 1 vehicle |
Rounding 3.3 down to three vehicles is tempting. Do not do it. Three vehicles on a 25-minute cycle give you a departure every 8.3 minutes and room for about 180 riders an hour, short of the 200 you need at 8:15. The shortfall shows up as a line at the stop, and a line at the stop in week one becomes the story everyone tells about the closure.
Planning 25 riders into a 30-seat vehicle is deliberate. Riders do not arrive evenly, and a cluster of six cars pulling in at once fills the last seats. A 30-passenger minibus is a common fit for this kind of loop; if your peak rate is higher, the same math works with larger vehicles.
Phase 2: Design the service around the academic day
A temporary shuttle for daily commuters is not one loop at one frequency from dawn to dusk. It is a schedule with a shape, and the shape comes from your class timetable and office hours.
Hours of service
Set the first trip early enough for the earliest regular arrivals. If facilities and dining staff start at 6:30 a.m., the first departure from the replacement lot should be around 6:15. If the earliest class is 8:00 a.m., the peak should be at full strength by 7:30. The last trip back needs to cover the end of the last scheduled class plus a cushion, because nobody wants to finish a 9:10 p.m. lab and find the shuttle stopped at 9:00.
Headway by time of day
Continuing the example, a weekday schedule might look like this:
| Time band | Vehicles in service | Headway | Why |
|---|---|---|---|
| 6:15 to 7:30 a.m. | 2 | About 12 min | Early staff shifts, light student traffic |
| 7:30 to 9:30 a.m. | 4 | About 7 min | Morning peak, sized from the arrival curve |
| 9:30 a.m. to 3:30 p.m. | 2 | About 12 min | Class changes, midday trips, appointments |
| 3:30 to 6:00 p.m. | 3 | About 8 to 9 min | Afternoon departures, more spread out than arrivals |
| 6:00 to 9:45 p.m. | 1 | Fixed times tied to class end | Evening classes, late labs, library users |
The afternoon gets fewer vehicles than the morning because people leave as their own day ends rather than racing a shared start time. Your counts may say otherwise, so check.
Evening classes
With one vehicle in the evening, a plain loop can leave someone standing in the dark for 25 minutes. Instead, time departures from campus to class end times. If evening classes end at 7:45 and 9:15 p.m., schedule departures at 7:50, 8:05, 9:20 and 9:35 and publish them as fixed times. For an evening rider, a printed time is worth more than a frequency.
Weekends
Many campuses skip weekend service by opening close-in lots that are restricted on weekdays, which is often the cheapest fix. If weekend events, labs or residential staff depend on the closed lot, a reduced Saturday schedule with one vehicle may be enough. Ask the people who work weekends before you decide.
Shuttle bus, minibus or school bus?
For short loops, wide doors and low steps board faster than a highway coach, which matters when you need 25 people on in two minutes. Our comparison of shuttle buses and motorcoaches explains the trade-offs, and a dedicated shuttle bus rental is the usual default. Some campuses add a rented school bus for high-capacity peak runs when the ride is under 10 minutes. The article on how a shuttle differs from a charter clarifies how each is usually priced and scheduled.
Phase 3: Contract a service that can end early
A temporary campus shuttle sits between a one-day charter and a permanent transit contract. Construction timelines slip in both directions, and the agreement has to bend with them.
Blocks, minimums and spares
Operators usually price recurring work in weekly or monthly blocks, with a minimum number of hours per vehicle per day. That minimum shapes your schedule. In the example, the fourth vehicle is only needed from 7:30 to 9:30 a.m. If the daily minimum is four or five hours, that two-hour vehicle costs the same as one running until noon, so you might as well use it to add midday frequency, or ask whether a split shift covering the afternoon peak is possible. Read how charter and shuttle pricing is built before you lock in the shape of your day.
Ask for a spare vehicle, or at least a firm replacement time. A four-vehicle loop that loses one at 7:50 a.m. drops to a 10-minute headway at the worst moment. Get the answer in writing.
Driver consistency and hours
Daily commuters notice when the same driver shows up each morning. That driver learns where people wait in the rain, which departure gets the 8:10 rush and which rider needs the bus to kneel. Ask whether the operator can assign a consistent core group of drivers for the whole contract. A service day of 6:15 a.m. to 9:45 p.m. is also far longer than one driver can legally cover. Federal limits on driving and on-duty time for passenger-carrying drivers are summarized on the FMCSA hours-of-service page, so a full-day loop needs at least two shifts, and the operator should show you how they are covered.
What goes in the quote request
Send each operator the same packet so the quotes are comparable:
- Start date, expected end date and the reason for the closure.
- Replacement lot address, every stop, and the measured one-way running time at peak.
- The service table by time band, with vehicles and target headway for each.
- Days of service, including academic holidays and breaks with no or reduced service.
- Vehicle type, minimum seating, and at least one wheelchair-accessible vehicle in service or on call.
- Spare vehicle requirement and maximum replacement time.
- Where vehicles stage overnight and between peaks.
- Who counts riders, how, and how the data reaches you each week.
- Terms for extending week by week, and for ending early with notice.
- Insurance certificate requirements, and who on campus signs.
The last item trips up many campus projects, because parking, facilities and procurement may each assume someone else is the signer. Our note on who should sign a bus contract is written for exactly that confusion.
If construction ends early, or late
Garages reopen in sections, contractors finish ahead of schedule, and some projects drag into the next semester. Ask how much notice is needed to drop a vehicle, end service or add weeks, and whether an early end carries a fee. Our guide to changing booked dates covers how operators usually handle shifting schedules, and the cancellation checklist lists what to ask before you sign. If a proposal shows held dates rather than a booking, check the difference between a quote and a confirmed reservation.
Phase 4: Announce it like a service, not a construction notice
Construction notices focus on what is closing. Riders want to know what to do instead. Treat the launch as the introduction of a new transit service.
The 30 / 14 / 3 notice schedule
| When | Who receives it | What it says |
|---|---|---|
| 30 days out | Permit holders for the closing lot, department heads, HR, commuter student groups | Closure dates, reason, replacement lot, that a shuttle will run, link to map and FAQ |
| 14 days out | Same list, plus campus newsletter and staff council | Full schedule by time band, stop photos, evening departure times, accessibility contact |
| 3 days out | Permit holders directly, by email and text | Lot closes Monday, park here, board here, first shuttle 6:15 a.m. |
| First morning | Staff at both stops | Wayfinding, answering questions, handing out schedule cards |
The 30-day notice gives people time to rearrange carpools and childcare. The 3-day notice is the one most people read, so keep it short.
Maps and signage
Publish one simple map showing the replacement lot, the boarding point, the route and the drop-off stop. Put temporary signs at the lot entrance pointing to the stop, and at each stop post the schedule and a phone number. Use the same stop names on the map and the signs. If the map says “Lot W Shelter” and the sign says “West Shuttle Stop,” someone will stand in the wrong place.
The permit holder FAQ
Build an FAQ page from the questions the parking office will hear in week one:
- Does my current permit work in the replacement lot, and will its price change?
- What if I have a disability placard or a medical need to park close?
- What happens if I miss the last shuttle?
- Can I bring a bike, stroller or equipment on board?
- Where do visitors and contractors park?
Real-time arrival information
If your campus already has a transit tracking app, ask whether the temporary vehicles can be added. Some operators can supply GPS feeds; some campuses place portable trackers on contracted buses for the project. If neither works, a printed schedule and a reliable headway come close. Riders mind not knowing how long they will wait more than the wait itself.
A feedback channel
Give riders one place to report problems, a short form or a dedicated email address, and put it on the signs and FAQ. Read it every day for the first two weeks. “The 8:12 was full and drove past me” is data you can use. Without a channel, the same complaint goes to a dean.
Phase 5: Run it, count it and fix it
No temporary shuttle runs exactly to plan in week one. What matters is how quickly you adjust.
The first week
Expect the first Monday to be heavier and lumpier than your model, because unsure people leave home early and arrive at once. Put the spare vehicle in service that morning if you can, and station a staff member at each stop from 7:00 to 9:30 a.m. for the first three days. By Thursday you will know whether the peak headway is right, whether the boarding point sits where people actually park and whether the evening times match class endings. Typical fixes include moving the boarding point, adding a second one in a large lot, trimming midday frequency and adding a departure just after the last evening class.
Counting riders
Simple methods work for a temporary service: driver clicker counts recorded per departure, a staff tally at the stop during the first two weeks, a permit or ID scan at the door if your system supports it, and a midmorning car count in the replacement lot. Ask the operator to fill in a trip sheet like this and send it weekly.
| Date | Departure | Direction | Vehicle | Boardings | Left behind? | Notes |
|---|---|---|---|---|---|---|
| Mon | 8:07 | Lot to campus | Bus 3 | 28 | Yes, about 4 | Rain, heavy load |
| Mon | 8:15 | Lot to campus | Bus 4 | 22 | No | |
| Mon | 12:40 | Campus to lot | Bus 1 | 6 | No | Light midday |
The “left behind” column matters most. One pass-up at 8:07 is a blip. Pass-ups at the same departure three days running mean you need another vehicle or a short-turn trip in that slot.
The complaints log
Keep a running log of date, time, stop, complaint and response. If five complaints in a week mention the 5:15 p.m. departure, that slot needs attention. The log also lets you show someone senior both the problems and the fixes when they ask whether the shuttle is working.
Rain and snow
Bad weather pushes people who would have walked onto the shuttle and slows everyone’s boarding. Agree on a plan in advance: the spare goes into service when rain or snow is forecast for the morning peak, and the operator has a clear contact for snow delays and route changes when a gate or road is unplowed. If the stop in the replacement lot has no shelter, a rented canopy for the length of the project is cheap.
Accessibility
A temporary shuttle still has to serve riders who use wheelchairs, walkers or canes. Two approaches work well together. Keep at least one lift- or ramp-equipped vehicle in the regular rotation and publish which departures it covers. Then offer an on-call accessible ride, booked by phone, from the replacement lot to the rider’s building door, similar to paratransit, coordinated with your disability services office. Our guide to booking accessible buses lists what to ask about lifts, securement and advance notice. Also check whether accessible spaces near the core can be protected during the closure, since for some people no shuttle is a substitute.
Safety at the stops
Most of the risk lives at the stops. Pick a boarding point where the bus can pull in without backing up, riders do not cross the main drive aisle and lighting is good after dark. At the campus end, work with campus police so the shuttle is not double-parked at class change. Our bus parking and staging guidance covers layover space, and the BusXOXO safety standards page explains what we check on the operators we work with.
Phase 6: Wind it down on purpose
The end of a temporary shuttle is easy to fumble. The lot reopens, the shuttle stops, and a handful of people who never got the email stand at the stop at 7:45 a.m. A planned wind-down avoids that.
Phased reduction
If the facility reopens in sections, as many garage repairs do, reduce the shuttle in step with it and tie each step to a date in your notices.
| Stage | Trigger | Shuttle change | Notice |
|---|---|---|---|
| Partial reopening | About half of spaces return | Peak reduced to 2 vehicles, midday to 1, evening unchanged | 7 days before, email and stop signs |
| Full reopening | All spaces return | 1 vehicle, peak hours only, for one week | 7 days before, plus a reminder 2 days before |
| Service ends | One week after full reopening | No service | Signs at both stops for 2 weeks after |
Leave the “service has ended” signs up for two weeks. Someone always comes back from leave the day after you take them down.
The final ridership report
Write a short report while the numbers are fresh: total and average daily boardings, peak half-hour load, pass-ups by week, accessible trips, complaints and how they were resolved, and cost per boarding. Compare the actual arrival curve with the one you planned from, and note three or four lessons in plain sentences, such as “Gate data overstated real use” or “Rainy Mondays needed a fifth vehicle.” This report is the most valuable thing the project leaves behind for the next closure. It also gives your sustainability office real commuter data and can start a conversation about a permanent park-and-ride; our article on lower-emission bus travel may help frame it.
Frequently asked questions
How many shuttles do we need when a campus parking lot closes?
Start from your busiest half hour of arrivals, not the number of spaces. Convert that half hour into riders per hour, divide by a planning load below the seat count, and you get trips per hour. Divide the round-trip cycle time by the resulting headway and round up. Then add one spare vehicle.
How far in advance should we book a temporary shuttle service?
Six to eight weeks before launch is a comfortable window for a multi-week service, especially if procurement is involved. That leaves time to compare quotes, sign the agreement, and send a 30-day notice to permit holders with confirmed details.
What headway should a parking lot closure shuttle run?
Many campuses aim for something in the range of 5 to 10 minutes during the morning peak and 10 to 15 minutes midday, with fixed departure times in the evening. The right number depends on your arrival rate, the length of the loop and how many vehicles you can afford.
What happens if construction finishes early?
That depends on the terms you negotiate. Before signing, ask how much notice the operator needs to reduce vehicles or end service, and whether an early end carries a fee. Writing a week-by-week extension and early-end clause into the agreement avoids surprises.
How do we serve riders who use wheelchairs during the closure?
Include at least one lift- or ramp-equipped vehicle in regular service and publish which trips it covers. Many campuses also offer an on-call accessible ride from the replacement lot to the rider’s building, coordinated with the disability services office.
How should we count shuttle riders?
Driver clicker counts recorded on a trip sheet are enough for most temporary services. Add a column for riders left behind at each departure, since pass-ups tell you where to add capacity. If your ID or permit system supports a scan at the door, that gives exact counts.
