RDV Systems used mobile LiDAR, high-resolution imagery and RSA 3D's automated analytics to find sight-distance, geometric and roadside hazards along the whole Telegraph Road corridor, with far less field work.
6 analysesstopping, passing and intersection sight distance, curves, safe speeds and clear zones, in one digital environment.
RDV Systems used RSA 3D to run a comprehensive roadway safety analysis along Telegraph Road in Stafford County, Virginia. Using LiDAR, high-resolution imagery and automated analytics, the study evaluated stopping sight distance (SSD), passing sight distance (PSD), intersection sight distance (ISD), horizontal curve geometry, safe speeds and roadside clear-zone conditions. The analysis identified potential sight-distance, geometric and roadside hazards to support targeted engineering review and proactive safety improvements.
Telegraph Road has multiple horizontal curves, varied roadside development and a mix of residential and commercial frontage, which raise concerns about run-off-road crashes, limited sight distance and roadside hazards. Traditional assessments can require extensive field work, which takes time and exposes workers to traffic.
Using mobile LiDAR and high-resolution imagery, RSA 3D automated multiple roadway-safety analyses across the Telegraph Road corridor. It also classified roadside objects, including vegetation, utility poles, signs, buildings, fences and mailboxes, and correlated them with the roadway geometry to identify potential safety deficiencies.
By combining multiple roadway-safety analyses within a single digital environment, RSA 3D gave engineers a consistent, corridor-wide view of potential safety concerns. The findings can focus engineering review and prioritize mitigation such as vegetation clearing, object relocation, speed review or roadway improvements.
The Telegraph Road project shows RSA 3D evaluating multiple roadway-safety conditions across an entire corridor, from sight distance and horizontal curves to speed and roadside hazards. By combining LiDAR, imagery, automated analytics and engineering-ready outputs, RSA 3D gives a repeatable way to identify potential safety concerns and prioritize further engineering review.
Case study
After pedestrian incidents at a busy campus intersection, the University of Arkansas and Olsson used RSA 3D to measure how well drivers and pedestrians can see each other, movement by movement, in one LiDAR-based 3D model.
Case study
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.
Case study
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.
