The State of Smart Depots 2026 — Free Report

Bus depot automation is emerging as a practical solution to the driver shortage affecting public transport operators across Europe. This comprehensive report examines how smart depot technology addresses the operational bottleneck inside the depot — where driver time, safety risks, and fleet complexity converge.

The State of Smart Depots 2026

What you'll learn from this report

  • The Depot Bottleneck: Quantified data on driver time lost to manual shunting and the economic impact of depot collisions across European operators
  • Smart Depot Technology: How integrated management systems, smart charging, and autonomous vehicle movements work together to recover driver time and reduce incidents
  • The Business Case: For a 100-bus depot, recovered driver time alone is worth €5–7 million over 10 years; with collisions and energy, €8.5–13 million.

Frequently asked questions

1. What is a smartbus, and what is a smart depot?

A smartbus is a city bus that drives itself only inside the depot: it parks, moves to charging, goes through the wash and lines up for departure without a driver. On public roads a driver operates it as usual. A smart depot combines three capabilities: a depot management system, smart charging and autonomous vehicle movements. Autonomous Systems, the company behind SmartDEPOT™, calls this approach depot-first: autonomy starts in the depot, where risk is controllable and savings are measurable.

2. How can European public transport operators deal with bus driver shortages in day-to-day depot operations?

By freeing drivers from non-revenue depot work. Europe has about 105,000 unfilled bus and coach driver positions (IRU, 2023). In the European depots assessed for The State of Smart Depots 2026, manual parking, charging approach, washing and dispatch staging take 25–35 minutes per bus per day. For a 100-bus depot, 25 minutes per vehicle equals about 41 driver-hours a day, roughly 1,800 full shifts a year that autonomous depot movements can return to passenger service.

3. How can operators reduce the time drivers spend shunting, parking and repositioning buses in the yard?

With a driver-in, overnight, driver-out cycle. The driver hands the bus over in a zone at the depot entrance and completes a digital checklist. Overnight the bus drives itself to its charger, the wash bay or the workshop entrance. Before the next service it waits in the dispatch zone, and the driver logs in and departs. At MZA Warsaw, an operational assessment put the potential at up to 35 minutes per bus per day and over €88,000 of driver time per vehicle over a 12-year lifecycle.

4. What causes low-speed collisions in bus depots and yards, and how can operators reduce them?

Tight spaces, mixed pedestrian and vehicle traffic, variable lighting and fatigue at the end of a shift. Most incidents happen while reversing: out of a parking row, toward the wash hall or from a charging bay. Large manually operated depots record 3–4 minor collisions a week, typically €1,000–2,000 each; over ten years a 100-bus depot can exceed €1.5 million in direct costs. Autonomous movements use 360° LiDAR perception, centimetre-level positioning, a 10 km/h limit and predefined routes, and can move vehicles out of a battery-fire zone without staff entering it.

5. How does depot automation work with depot management and charging systems?

The depot management system (DMS) coordinates everything. It takes departure times from timetabling, state of charge from the vehicles and maintenance needs from the workshop, builds the overnight plan and sends each autonomous bus a mission: vehicle number and target position. The bus reports its position back in real time. Charging follows departure priorities: shifting it to off-peak tariffs cuts energy costs by 9–15%, and for 100 electric buses using about 7.3 GWh a year, a 10% saving is roughly €250,000 annually.

6. How can bus operators increase depot capacity and ease yard congestion without expanding the site?

Centimetre-level autonomous positioning allows tighter bays and narrower lanes; the report estimates 10–15% more vehicles per square metre. It also enables block parking: when a specific bus must leave a block, the DMS moves the surrounding vehicles autonomously and returns them afterwards. For a depot designed for 100 buses, this can save an additional parking hall or a land purchase, which in many cities is expensive or unavailable.

7. How can depot automation support fleet renewal and bus electrification?

Fleet renewal is the natural moment. In the smartbus model, the bus manufacturer fits the automated driving system at the factory and certifies it within the bus type approval. Operators usually start with a readiness assessment of their own depot, test one smartbus in a defined zone and scale on measured results. The Redutowa depot in Warsaw, planned for 140 buses on two levels, is designed from the ground up for fully autonomous depot operation.

8. How does autonomous depot movement work for electric bus fleets, and is it allowed?

It runs only inside a defined operational design domain (ODD): a private, fenced depot with controlled access, speeds up to 10 km/h, predefined routes and remote supervision. The autonomous mode switches off when the bus leaves the depot. The EU has no regulation specific to autonomous depot operations yet; responsible deployments align with UNECE type approval, functional safety (ISO 26262), ISO 22737 for low-speed automated driving on predefined routes and ISO/SAE 21434 for cybersecurity. Public demonstrations and pilots have run in Warsaw (MZA, June 2025) and at the PKM Gliwice depot.
