Low Shared Fleet Utilization May Reflect Access Barriers, Not Excess Vehicles

A low utilization rate can make a shared vehicle look expendable even when employees need transportation. Before reducing fleet size, managers should find out whether drivers can locate, reserve and access the vehicles already available.

The distinction matters in shared fleets at universities, utilities, public agencies and other multi-department organizations. If employees cannot use a vehicle when they need one, they may drive personal cars, seek mileage reimbursement, rent vehicles, delay trips or ask for dedicated vehicles. The shared fleet then records little use, while transportation demand continues elsewhere.

Utilization is a measure of what happened under the current operating process. By itself, it doesn’t explain why a vehicle sat idle. Reservation attempts, denials, eligibility records, key access, location, maintenance and alternative transportation spending help fill in that picture.

Eight barriers that can conceal demand

1. Keys are available only during staffed hours

A vehicle can be parked, operational and unreserved, yet unavailable in practice if its keys are kept in an office that closes at 5 p.m. An employee leaving at 6 p.m. or starting a trip early the next morning may have to use another option.

That choice can leave the shared vehicle idle while the organization pays for mileage reimbursement or a rental, or the trip is delayed. Before reading after-hours inactivity as excess capacity, check whether drivers can retrieve keys when their work requires it.

2. Booking takes too much effort

Calls, emails, spreadsheets, approval waits and in-person visits can turn a simple reservation into a chore. Drivers often choose the option that takes less effort. If booking a pool vehicle requires several steps while claiming mileage for a personal car is straightforward, an available shared vehicle may lose out.

Self-service booking can reduce that friction while preserving the organization’s operating rules. Repeated calls to staff, abandoned requests and manual workarounds can help identify where the current process is getting in the way.

3. Department boundaries keep vehicles from reaching users

One department may have several vehicles sitting idle while another faces recurring shortages. If employees in the second department can’t book the first department’s vehicles, the organization can have unused capacity and unmet demand at the same time.

Broadening access or placing suitable vehicles into a shared pool may improve use without increasing fleet size. An organization-wide utilization average can obscure these department-level differences. Managers need to understand whether vehicles are available to the people who need them, not just whether the overall percentage looks acceptable.

4. Driver records block eligible users

Driver controls help ensure that vehicles go to eligible employees. But incomplete, outdated or inconsistent records can prevent an authorized driver from booking. The right response is to keep eligibility information connected to the reservation process and up to date, so controls don’t create avoidable barriers.

5. Employees can’t see what’s available

Availability may be scattered across spreadsheets, calendars, whiteboards, email threads or staff members’ knowledge. A driver at one site may hear that no vehicle is available while a suitable one sits unused nearby.

A shared view of reservations and availability can help drivers and fleet staff spot capacity that was previously hidden. For multi-location operations, it can also show whether a vehicle needs to move or simply needs to be visible to more users. How to Maximize Vehicle Utilization Across Multiple Locations discusses how location-level visibility can reveal these imbalances.

6. Vehicles are positioned far from demand

A fleet may have enough vehicles across all its sites, but not where people need them. One location can have low utilization and few denials while another has frequent booking shortages. Adding a vehicle to the busier site may increase total fleet size while existing capacity remains idle elsewhere.

Location and vehicle type both matter. Reviewing use and denials by site can point to a reassignment or temporary transfer before a new vehicle is considered. Fleet-wide availability doesn’t guarantee that a vehicle is accessible to the employees who need it.

7. Reservation rules add avoidable friction

Rules can support fair access and appropriate use. Excessive advance notice, narrow pickup windows, complicated approval chains or inconsistent requirements between sites can also discourage legitimate bookings.

Review rules that repeatedly generate exceptions, manual overrides, staff calls or abandoned reservations. When employees and staff regularly work around a requirement, it’s useful to ask what purpose it serves and whether the process still fits how the fleet operates.

8. Drivers don’t trust the process

Missing keys, double bookings, vehicles that aren’t ready despite a confirmed reservation, poor vehicle condition and last-minute cancellations can make employees reluctant to depend on a shared fleet. They may turn to personal cars, rentals or department vehicles instead.

That can create a cycle: poor experiences drive down use, low recorded use suggests surplus capacity, and vehicle reductions can make it harder for employees to find a vehicle when they do need one. Ask drivers whether they trust the reservation and handoff process before treating low use as proof of low demand.

Read utilization alongside access and demand signals

No single measure can establish why a vehicle is underused. Comparing several signals gives fleet managers a better basis for deciding what to change.

• Completed reservations: Low use over time deserves attention, but it starts the investigation rather than settling it.
• Reservation attempts and denials: Requests that can’t be fulfilled may point to scheduling problems, location mismatch, restrictive rules or poor distribution. A vehicle class with few completed trips but repeated denials elsewhere may still be serving a real need. See How to Use Reservation Denials to Decide Whether Your Fleet Needs More Vehicles.
• Key access: Compare bookings with key pickups and returns. Check whether access matches reservation times, including outside staffed hours.
• Actual movement: Compare reservations with mileage, telematics or completed-trip records. A booking doesn’t prove that a trip occurred; this comparison can expose no-shows or reservations that block capacity.
• Alternative transportation: Review personal mileage reimbursement, rentals, rideshare and other transportation costs. Low shared-fleet use alongside rising reimbursement warrants a closer look at why employees are choosing other options.
• Driver feedback: Ask whether employees can find and book appropriate vehicles, collect keys when needed and use another transportation option instead. Their answers can explain patterns in the operational data.
• Maintenance and mission: Check whether downtime depresses recorded use and whether the vehicle serves a specialized need that isn’t captured by routine trip frequency.

The relationship between these indicators can guide the next question. Low use combined with easy access, few requests and reliable nearby alternatives may point to spare capacity. Low use paired with high reimbursement, frequent denials at another site, limited key hours or repeated manual overrides points toward an access or distribution problem worth investigating first.

Diagnose before changing fleet size

Removing vehicles based on a utilization figure alone can leave the underlying access issue untouched. If employees already struggle to obtain keys or book a vehicle, reducing the pool may lead to more denials, rentals, reimbursements or requests for dedicated vehicles.

A more useful sequence is to measure use, investigate the cause, address barriers, then measure again before adjusting capacity. Depending on what the evidence shows, changes could include self-service reservations, access outside staffed hours, automated key pickup, updated driver records, simpler booking rules, cross-department access, clearer availability information or moving vehicles between locations.

After making a change, allow new usage patterns to emerge. The point is to establish a more accurate baseline for demand under a process that employees can use reliably.

Connect operational data to understand the cause

A utilization report might show that a particular vehicle was used on 34% of available days. That figure describes the result, but it doesn’t reveal how many people requested the vehicle, whether eligible employees could book it, whether they could collect the key or whether maintenance kept it out of service.

Put reservations, driver records, access, mileage or telematics, maintenance, location, operating costs and reimbursement alongside utilization. Together, these records can help managers distinguish low need from a vehicle that was poorly placed, difficult to book or unavailable when demand arose.

Sonoma County example

Sonoma County Human Services manages shared transportation for more than 1,000 drivers across multiple locations. The organization faced limited access, administrative workload and inconsistent usage patterns.

By centralizing reservations, improving access controls and giving fleet managers clearer utilization information, it supported wider shared-fleet access while reducing the manual work involved in coordinating vehicles. The example underlines a practical point: a vehicle contributes to a shared fleet only when drivers can find it, reserve it, qualify to use it, collect the key, complete a trip and return it through a workable process.

When low use does point to surplus capacity

Access barriers don’t explain every underused vehicle. After checking that employees can book and reach the vehicle, consistently low use across multiple periods may support a capacity decision—especially when there are few requests or denials, suitable alternatives nearby, no specialized mission and ownership costs that are high relative to use.

Managers can then consider whether to share the vehicle more broadly, reassign it, move it to another site, keep it through its current service life without replacing it, or remove it.

Run an access audit before labeling a vehicle unnecessary

For a vehicle or vehicle class with lower-than-expected utilization, review the following questions:

• Demand: How many trips were completed? How many people requested the vehicle type? Were requests denied? Does demand vary by season, and are employees using alternatives?
• Reservations: Can drivers book for themselves and see availability? Are approvals necessary? How often do staff make manual exceptions? Are rules unnecessarily restrictive?
• Eligibility: Are driver records current? Can qualified employees book easily? Do department limits block legitimate use?
• Keys: When can drivers collect them? Is after-hours access possible? Do pickups match reservations? Are missing or unavailable keys causing lost use?
• Location: Is the vehicle near the employees who need it? Is demand stronger at another site? Can users see availability across locations?
• Actual use: Do bookings correspond to trips? Are no-shows blocking access? Is maintenance downtime lowering utilization?
• Alternatives: Are employees using rentals, personal vehicles or requesting dedicated vehicles?

If these checks show transportation demand but little shared-fleet use, address the access problem and then reassess capacity.

Before reducing capacity, compare five underused vehicles—or one vehicle class—with reservation attempts, denials, key access, driver eligibility, maintenance downtime, location and mileage reimbursement. Decide whether the evidence points to low demand or a barrier to use, fix access where needed, and measure again. Then choose whether to retain, share, reassign, leave unreplaced or remove the vehicle.
