Generative TCP Design Drop a work area.
Drop a work area.
The plan designs itself.
LaneMarker reads the real road — lanes, speed, intersections, driveways — and designs the traffic control plan around your work: taper, buffer, arrow board, sign ladder and every device, cited to MUTCD 11th Edition and your state’s rules. Move it, and everything moves with it. Try it:
Typical applicationRight lane closure
Merging taperL = 540 ftW × S = 12 × 45
Buffer space360 ftby posted speed
Sign spacing A · B · C350 fturban, high speed
Devices—re-designed in —
It asks: the closure ends at the near side of the intersection (TA-21). Keep the right turn open, or close it?

The plan set
Sixty seconds ago, this plan set was a satellite photo.
- Intersections, pedestrians and bicycle lanes handled per MUTCD 11th Edition
- California MUTCD and Caltrans standard plans built in; more states as rule packs
- Stops and asks at real decisions — it never invents your facts
- Aerial, asphalt or linework sheets with title block, match lines and sign legend
- Export to PDF, or DXF straight into your CAD
One studio
Studies, plans and drawings. On one live map.
Every module shares the same network, scenarios and volumes — change a lane once and every figure, table, sheet and report follows.

AI Build
Draw a box. Get the real road network.
Lanes, turn pockets, medians, driveways, signals, stop control and roundabouts — read from the imagery and ready for analysis in minutes, not an afternoon of clicking.
- Each approach read separately — dual lefts, right-turn bays, storage
- Checked over the satellite view so you can verify at a glance
- Fix anything by hand, by chat, or by boxing a mistake for the agent
Trip generation & distribution
Every percentage, justified — direction by direction.
Land uses become AM and PM trips, then flow through the network intersection by intersection. The agent explains each route, and the movement table stays fully editable.
- Pass-by and internal capture for mixed-use sites
- Cumulative developments distributed the same way as your site
- Import an agency distribution or shift trips between routes
PM peak · 61 trips in, 38 out · every route explained and editable
Sample data Agents & chat
Ask like you’d ask a senior engineer.
LaneMarker AI runs the right agents, questions assumptions, explains its reasoning and edits any output with you. When your process is unique, describe it once in Workflow Studio and it becomes your own agent.
- Dozens of agents — volumes, LOS, mitigation, safety, work zones, figures
- Reasoning and sources shown for every result
- Team workflows shared across your company workspace
Add a 120-unit apartment on the NE corner and tell me what changes at Main & Oak.
LaneMarker AIAdded 120 units (multifamily, mid-rise). That’s 49 AM and 61 PM trips. I routed 55% north on Main based on the employment centres. Main & Oak PM goes from LOS D (41 s) to E (63 s) — the NB right turn is the critical movement. Want me to test a right-turn lane?
Yes, and draft the memo.

Two minutes. The whole studio.
Network on the map, the trip distribution agent reasoning live, the agent catalog, Workflow Studio and the report.
Engineer in the loop
AI that works like a careful engineer.
Fast is only useful if it’s right. LaneMarker is built to be checked.
Cites the rule
Every taper, spacing and LOS result points to the standard and inputs behind it.
Asks, doesn’t guess
When a decision needs judgement, the agent stops and asks you instead of inventing facts.
Everything editable
Change any lane, volume, device or sentence. Results update downstream.
Your data stays yours
Encrypted, role-based workspaces. We never sell your data.
Who it’s for
Built with the people who do the work.
Traffic engineering consultants
Most of a traffic study’s budget goes to coding networks, balancing volumes, re-keying timing and formatting figures.

FAQ
Frequently asked questions
What is LaneMarker AI Studio?
LaneMarker AI Studio is one AI studio for every traffic deliverable: traffic impact studies, EIR transportation analysis, safety studies, speed studies, traffic control plans, and design and drafting from aerial imagery. It all runs in the browser on one live map, with agents you can click or simply ask.
What is Generative TCP Design?
You draw the work area; LaneMarker designs the traffic control plan. It reads the real road — lanes, speed, intersections, driveways — and places the taper, buffer, arrow board, signs and devices per MUTCD 11th Edition and your state’s rules. Move the closure and the whole plan re-flows in seconds, then export plan sheets to PDF or DXF.
How is LaneMarker AI Studio different from LaneMarker PlanCheck?
AI Studio is where you create studies, plans and drawings. PlanCheck reviews plans — yours or an applicant’s — against MUTCD and your local standards, sheet by sheet, and produces a cited redline report. Many teams use both.
Who is it for?
Traffic engineering and planning consultants, city, county and DOT engineers, land developers and traffic control contractors.
Do engineers stay in control?
Yes. Every agent shows its inputs and reasoning, cites the standard it applied, asks when a decision needs judgement, and lets you edit any value. Nothing leaves LaneMarker without an engineer accepting it.
Is my project data private?
Your projects stay in your workspace. Data is encrypted in transit and at rest, access is role-based, and we never sell your data or use it to serve other customers.
See your own study area in LaneMarker AI Studio.
Bring a corridor or a site you are working on. In 30 minutes we will build the network, run the analysis and show you the report — on your project, not a canned demo.
