Road safety and visualization for infrastructure

See the crash before it happens.

Road Safety Audit 3D finds the sight-distance failures crash data can't, and 3D Visualization lets everyone see the design. Trusted by state DOTs since 2005.

Upload a LiDAR scan or a CAD design. Get a road safety audit.

Road Safety Audit 3D, run in the cloud on the road you already scanned or the one you are still designing: ten analyses per corridor, checked against AASHTO.

Every station, not a sampleSight lines are rendered station by station along the whole corridor.
The AI names what blocks the viewTerrain, vegetation, a crest, a guardrail, a pole or a sign.
Findings meet your crash recordsSo the fixes you fund are the ones that prevent real crashes.

A simulated corridor beside you, running the real rule: 495 ft of stopping sight distance at 55 mph, from a 3.5 ft driver eye to a 2 ft object.

Two products, one goal

Safer roads and designs everyone understands

Road Safety Audit 3D

Find hazards before construction, not after crashes

A systemic 3D audit of new designs and existing roads that does not depend on crash history.

Stopping, passing and intersection sight distance, station by station
Curves, clear zones, guardrail warrant, glare and drainage
AASHTO and state DOT criteria, with reports, video and GIS layers

3D visualization

Your design, built in Unreal Engine and streamed to a browser

We turn the design files into a photoreal, geometrically accurate model in Unreal Engine, then stream it from cloud GPUs — a reviewer needs a link, not a workstation.

Built from your DGN, DWG, OpenRoads or Civil 3D files, so the geometry is the design itself
Real-time light, weather, traffic and time of day — drive it, walk it or fly it
Video, stills and guided virtual tours all come out of the same model
The rendering happens in the cloud, so an office laptop runs it as smoothly as a workstation — no graphics card, no install

How it works

From your files to decisions in three steps

Send us your data
LiDAR, reality mesh or DTM for existing roads. DGN, DWG, OpenRoads, InfraWorks, Civil 3D or SketchUp for designs.
We analyze and model
Road Safety Audit 3D runs the sight-distance and safety analyses. 3D Visualization builds the shareable 3D model.
You get deliverables
Reports and CSV exports, stills, videos and virtual tours, all reviewable in a browser by anyone you invite.

Henderson Interchange

C A Group used RDV's 3D Visualization model to produce more than 65 miles of drive-through video for public outreach and RSA 3D to catch and correct sight-distance deficiencies before construction.

“We Had No Idea”

UDOT partnered with RDV Systems to adapt RSA 3D to analyze stopping sight distance across Utah's existing road network using annual LiDAR scans instead of CAD design files.

I-26 / SC-27 Interchange Reconfiguration

RDV Systems built an interactive 3D model of three alternative SC-27 interchange designs so SCDOT and Mead & Hunt could present them at their first public meeting using 3D Visualization.

In their words

What project managers and engineers say

“We had no idea that a company that was coming to us to do 3D visualizations had the ability to give us this product.”
Carlos Braceras
Executive Director
Utah Department of Transportation
Read the UDOT case study Watch his remarks from the ITE event
“The RDV models were the star of the show and made it possible for our team to share an extremely complex proposal with the public in a way that was easily understood.”
Richard Armstrong
Principal Engineer
Connecticut Department of Transportation
“The response of the public to the visualizations was enthusiastic. It helped them see the vertical aspect of the proposed alternatives in a way that wasn't possible with maps and plans.”
David Stark
Project Manager
North Carolina Department of Transportation
“As soon as we opened the RDV model the level of hostility in the room dropped by 80%.”
Dianne Wilson
Senior Public Involvement Officer
North Carolina Department of Transportation
“Technologies like RSA 3D are integral tools that allow safety professionals to solve problems previously deemed impossible and bring us closer to a future with zero roadway fatalities.”
Robert Miles
Director of Traffic Safety
Utah Department of Transportation
Read the UDOT case study
“The Public Hearing was a huge success and we couldn't have done it without RDV's work. The public was very receptive to the video simulations and it was a very positive tool to show property owners what the proposed freeway might look like.”
Tricia Brown
Project Manager
Arizona Department of Transportation
“Utilizing the visual assets of the 3D Visualization model, the public fully understood the innovative I-75 at Colonial Boulevard Interchange Improvements project since they could see the final configuration.”
Brian Bollas
Public Outreach Manager
Atkins North America
I-75 at Colonial Boulevard, Fort Myers, FL
“This is an awesome tool to have in construction meetings. Even with people who do know how to read a set of plans, this enhances and enriches that experience.”
Lynnette Russell
Assistant Chief, Project Management
Nevada Department of Transportation

“With the RDV model we were able to show the different designs in a fully interactive environment, create multiple poster board images, and simulate drive-throughs for the various configurations.”

“From the initial contact with RDV to the completed project, RDV always quickly responded to the changes requested by JF White. RDV also assembled several video versions to be used during the public meetings.”
Robert Nies
Project Manager
J.F. White Contracting Co.
North Washington Street Bridge, Boston, MA
“This was such a great tool to let people see an actual representation of what the end product was going to look like from any viewpoint that they wanted. We also brought it into a VR headset for people to actually experience it at the open house in virtual reality, as well as having the Navigator projected on the screen while playing the animation, and stopping to jump to different views to answer specific questions.”
Nicole Williams
Project Manager

“I was impressed with how quickly RDV was able to produce and update the model from our design CAD files. We were making a lot of design decisions and changes throughout the process and they did a great job of keeping track of changes and updating the 3-D models promptly.”
