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.

Safer roads and designs everyone understands

Road Safety Audit 3D finds hazards before crashes do. 3D Visualization lets everyone see a project before it is built.

Sight distance checked on a LiDAR scan of an existing road

Find hazards before construction, not after crashes

A 3D safety audit of new designs and existing roads that does not wait for crash history.

  • Fix sight-distance and roadside problems while the design can still change
  • Rank the riskiest spots on existing roads, so safety funds go where they prevent crashes
  • Defensible findings against AASHTO and state DOT criteria, as reports, video and GIS layers

  1. In 123BIMLive

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

    Step 1 of 3

    Send the scan or the design

    The LiDAR scan of a road you already manage, or the CAD design you're still working on. It all runs in the cloud.

  2. Step 2 of 3

    Every station gets checked

    Sight lines are drawn station by station along the whole corridor and checked against AASHTO, not sampled.

  3. Step 3 of 3

    Each failure names its cause

    A crest, trees, a guardrail or a sign, so crews know exactly what to fix, and the findings line up with your crash records.

    The scene is a simulation running the real AASHTO stopping-sight-distance rule for a 55 mph road.

Ten analyses from one scan

Every analysis runs on the same scan, so adding one never means collecting data again.

  • A sight line measured ahead of a car on a two-lane highwayStopping sight distanceWhere drivers can't stop in time, what blocks the view (terrain, vegetation, a crest, guardrail, pole or sign) and a crash-risk score for ranking the fixes.
  • A car preparing to pass a truck on a two-lane roadPassing sight distanceZones striped for passing where a driver can't see far enough to pass safely, the setting for head-on crashes.
  • A sight triangle drawn at a rural intersectionIntersection sight distanceWhich movements at which intersections have a blocked view, so clearing, signal or geometry work goes where it counts.
  • A car on a tight horizontal curve with its radius markedHorizontal curvesCurves whose safe speed falls below the posted speed, the candidates for advisory speeds, chevrons or re-banking.
  • Standing water across a flat section of highwayFlat spotsThe flat spots where water stays on the road, so drainage fixes target hydroplaning and ice risk.
  • Low sun shining straight down a highwaySun glareWhich stretches blind drivers, and at what times of day and year.
  • A steep embankment beside a mountain road, highlighted in redGuardrail warrantWhere a barrier is warranted along the corridor, and where one is not, before crews install or remove guardrail.
  • Embankment slopes along a divided highway, colored by steepnessEmbankmentsSide-slope geometry for designers, delivered as DXF cross-sections without sending a survey crew.
  • The roadside recovery area beside a highway, green where clear and red where notClear zoneTrees, poles and slopes in the recovery area, where a vehicle that leaves the road has no room to recover.
  • A stop sign detected and outlined in a camera frameTraffic signsA georeferenced sign inventory for the corridor, without a crew walking it.

What DOT leaders and engineers say

From executive directors to the engineers who ran the public meetings.

All testimonials
  • “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.”

  • “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.”

  • 80%less hostility in the room once the RDV model opened

    “As soon as we opened the RDV model the level of hostility in the room dropped by 80%.”

  • “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.”

  • “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.”

  • “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.”

  • “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.”

  • “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.”
