Default street setups

Enter the street address or intersection first.
Let Roadscape auto-fill starter geometry, or choose a preset category manually.
Pick the vehicle that must fit: van, bus, fire truck, semi, or custom.
Enter the corner shape: turn angle, curb radius, lane width, island/buffer.
Adjust driver line and speed if real video shows wide or tight turning.
Read the result: green clears, yellow is tight, red means curb/body strike risk.
Optional: upload a plan/aerial screenshot and scale it so the overlay matches the street.

Start here: If you only know one thing, enter the curb radius and lane width first. The tool updates live.

Example

Start by entering the street address or intersection. Roadscape can load starter geometry, then you can adjust measurements, presets, speeds, and vehicle type.

Data status: Default location is assumed unless edited. Verify any auto-filled values.

Import Roadscape scene JSON

Demo mode: run the sim, use presets, and take screenshots. Full JSON/project/packet ZIP exports unlock after purchase or service signup. Free demo resets after 4 days on this browser. No IP tracking, fingerprinting, or hidden analytics gate.

No cloud upload. Deterministic inputs and outputs for consultant or PE review.

Roadscape disclosure

This demo is for screening and visualization only. It is not a stamped engineering report, legal advice, or a final safety approval. Paid service packets can be prepared for third-party professional review where required.

Demo use runs in your browser. Roadscape does not use hidden pixels, fingerprinting, or IP tracking for this demo timer. Export/payment access is disclosed before purchase.

Optional module - truck access

Garage / HOA / commercial access.
Use this same turn model to check whether a service van, box truck, or delivery vehicle can reach a driveway, alley, loading bay, or apartment garage without clipping curbs or blocking lanes.

Not a separate brand lane. This is a Roadscape add-on for access checks and install planning.

Auto suggestions

Internal geometry suggestions.
Roadscape ranks current scene runs, flags crash / close call / pass, then suggests changes. Apply only if it fits the real site.

Speed sampling

Test speeders too.
Run cautious, normal, and random faster turns to show how speed changes curb/rub risk. Samples are saved into the packet JSON.

Processing control

Deterministic local geometry.
All analysis here is based on explicit inputs, vehicle templates, and local calculations. Any cloud or assisted processing must be separately scoped and approved.
