Our recommendation
Project Pass
Below 11 projects a year, paying once per project is the cheapest option. Each paid project stays unlocked permanently, CAD export and design vehicles included.
PathSweeper pricing at a glance: swept-path checks with the standard vehicles are free, with no time limit. The Project Pass unlocks a single project permanently for €39 one-time, including 65 official design vehicles (RBSV 2020, AASHTO, Austroads, UK), DWG/DXF import and DXF export. The Annual Pass covers unlimited projects for €399 per year. Planning teams start at €699 per user and year, an Enterprise instance with full data sovereignty (dedicated database hosted in Germany), your own vehicle fleet in the vehicle selector and the Vehicle Studio for complex vehicle combinations at €1,299 per user and year.
From first swept path to final proof — here's our roadmap.
All standard vehicle classes, from cars to articulated buses. The four free standard vehicles are generic templates with typical dimensions (not the official RBSV 2020 design vehicles).
Passenger car, delivery van, 2-axle truck and city bus with typical dimensions (generic templates, not the official RBSV 2020 design vehicles).
All 13 official RBSV 2020 design vehicles, from passenger car, truck, bus and refuse truck to semi-trailer, truck-and-trailer and articulated bus.
Both RBSV 2020 refuse trucks and the UK DB32 fire appliance. Germany has no fire-service design vehicle: fire appliances are specified in DIN standards, so they are built from the data sheet in the vehicle editor.
Multi-part vehicles with realistic articulation behavior.
Editor for individual design vehicles with your own dimensions.
AASHTO 2018 (USA), Austroads 2023 (Australia/NZ) and UK libraries are live; more countries are in preparation.
Physically accurate swept paths in real time — no approximations. Benefit from our precision calculation engine.
Realistic wheel angle calculation for precise turning circles.
Instant visualization of the total space requirement.
Swept paths with rate-limited steering arcs: gradual, physically accurate steering transitions instead of instantaneous angle changes.
Simulate reversing maneuvers with realistic steering behavior.
Semi-trailers, articulated buses and trailer combinations with full articulation kinematics and articulation-angle monitoring.
Seamless integration into existing planning workflows — no media breaks. Compatible with your favorite CAD tools.
Load site plans and floor plans as background images.
Use aerial imagery directly as a scaled planning base.
Edit swept paths directly in CAD software.
Standards-compliant documentation with dimensions and legend.
In-depth references on swept-path geometry, fire-truck access and design vehicles by country.
How Australian swept-path regulation works: Austroads AP-G34 design-vehicle and turning-path templates are a free PDF/DWG download, statutory limits are public via the NHVR, and only the Standards Australia AS 2890 series is paywalled. Every figure links to the exact source page.
AASHTO design vehicles (P, SU-30, BUS-40, WB-62, WB-67…) explained: what the codes actually mean, why the Green Book is paywalled, how to obtain the values legally, and which free public sources (FHWA, 23 CFR, state DOT manuals) are enough for pre-design swept-path work.
Which document governs your swept-path check: DB32 turning circles for residential schemes, DMRB CD 116/CD 123 on the Strategic Road Network, Manual for Streets, FTA design vehicles for freight access. What is free, what is paid, and what the highway officer will cite.
Latest articles on swept path analysis and access planning
AutoTURN Online costs $680 per year or $100 per month in the US and €630 per year in the EU, excluding taxes (as of 3 August 2026). All regional list prices, licence details and a cheaper alternative.
Three reasons for PathSweeper Enterprise: the Vehicle Studio for complex vehicle combinations, your own vehicle fleet in the vehicle selector, and full data sovereignty on a dedicated instance with its own database in Germany, with a negotiable DPA and no third-country transfers.
Swept path analysis software compared for 2026: browser-based tools, CAD add-ons and desktop suites, with verified pricing, vehicle libraries and trials.
Articulated vehicles in PathSweeper: swept paths for truck-and-trailer combinations, centre-axle trailers, semi-trailers and articulated buses, computed live in the browser with articulation-angle monitoring.
Realistic swept path simulation in the browser: rate-limited steering replaces the instant arc with a clothoid wheel-swing, like desktop tools. Try it free, save with a one-time Projekt Pass.
Export any calibrated swept path analysis as DXF or DWG for AutoCAD, BricsCAD or Allplan. A placeable reference point becomes (0,0) so it snaps exactly into place.
Swept paths for semi-trailer trucks: how an articulated tractor + trailer corners, max 16.50 m per § 32 StVZO, typical curve radii, and what planners need to watch out for.
What is the BO-Kraftkreis? § 32d StVZO explained simply: outer 12.50 m, inner 5.30 m, public-domain, and the pragmatic way to plan swept paths without buying the RBSV 2020.
Turning bays in dead-end streets: hammerhead, T-shape and circular variants, why the exact dimensions reside in the official RASt 06, public-domain sources for pre-design and the most common planning mistakes.
How planners in the US, UK, Australia, Canada and Germany find legally usable garbage truck dimensions: which official design-vehicle catalogue to obtain, which statutory maxima are free to cite, and which manufacturer datasheets give defensible pre-design values.
For free and with no signup, you can draw paths and compute swept curves directly in your browser with four standard vehicles (passenger car, delivery van, 2-axle truck, bus). You can calibrate scale on a site plan (including PDF site plans), draw turning paths, see the swept envelope in real time, and export as PNG/JPEG. The Project Pass (€39 one-time per project) adds 65 official design vehicles (RBSV 2020, AASHTO 2018, Austroads 2023 and UK libraries), custom vehicles, DWG/DXF upload and DXF export.
The free tier includes four generic standard-vehicle templates with typical dimensions, similar to the RBSV 2020 reference vehicles: a standard passenger car, a delivery van, a 2-axle truck, and a standard bus, not official RBSV 2020 reference vehicles, but sufficient for feasibility studies and plausibility checks. The Project Pass adds 65 official design vehicles from the RBSV 2020 (incl. refuse truck), AASHTO 2018, Austroads 2023 and UK libraries, and a custom-vehicle editor where you can enter dimensions from your own manufacturer data sheets. The articulated vehicles (semi-trailer, truck and trailer, centre-axle trailer, articulated bus, B-doubles and road trains) are included as well. There is no German design vehicle for fire apparatus: German fire appliances are described in DIN standards and are not part of RBSV 2020. The dimensions of a DLK 23/12 can be entered from the manufacturer data sheet in the vehicle editor, and the UK library includes a fire appliance (DB32 Fire Appliance).
No: the four free standard vehicles (passenger car, delivery van, 2-axle truck, city bus) are generic templates with typical dimensions, not the official RBSV 2020 design vehicles. They are sufficient for feasibility studies and plausibility checks. The €39 Project Pass includes all 13 official RBSV 2020 design vehicles (passenger car, additional truck classes, city and coach bus, refuse truck, plus the articulated semi-trailer, truck-and-trailer, centre-axle trailer and articulated bus) and the custom-vehicle editor. Fire apparatus are still in progress; the aerial ladder is specified in DIN EN 14043 / DIN 14502 (available from DIN Media). Note: the authoritative version of the FGSV regulation is the latest edition, available from FGSV Verlag, www.fgsv-verlag.de.
PDF site plans can be uploaded for free as a background: drop a PDF into the upload modal and calibrate the scale like any other site plan. DWG and DXF upload, plus DXF export, are included in the Project Pass (€39 one-time per project). As a separate free tool, you can use our public DWG to DXF converter without an account.
Yes. Swept-path calculation, calibration and PNG/JPEG export are permanently free and run entirely in your browser, with no signup required for the basic flow, no tracking cookies, and no third-party tracking. We use self-hosted, IP-anonymized analytics only. Only the optional Project Pass (€39 one-time per project) for the official design-vehicle libraries, custom vehicles and CAD export is paid.
No. PathSweeper runs entirely in your web browser (Chrome, Edge, Firefox). It is a lightweight alternative to installing heavy CAD plugins or vehicle tracking software.
