Highway / Roadway / Traffic Expert

Our highway experts examine crash sites, use field measurements, scrutinize crash scene photos and perform accident reconstruction to determine if highway factors and road conditions were a cause of the crash.  We determine safe curve speeds, sight distances, fundamental highway geometry, and traffic flow. Our experts evaluate roadway surface condition and drainage, roadway design, maintenance and operations, traffic signals and other traffic control devices, and the way in which humans respond to driving situations.

Our vehicle crash group consists of reconstruction experts, vehicle and highway engineers specializing in traffic road condition reports, investigations, and accident reconstruction.

    • Roadway Defect Causes Bicycle Collision

      A cyclist on a city street encountered a power company grate in the street, his front tire went into a gap in the grate, he crashed and was injured.

      We inspected the grate and showed that ordinary bicycle tires could readily be trapped by the gap, that the gap was in a normal bicycle travel path and that cyclist activity was common in the area. We also showed that gaps such as this have been known for a long time to be dangerous to cyclists, and that the gap made the grate dangerous in a manner that was a cause of the cyclist's crash and injuries.

      This event was typical of other bicycle collisions. The case resolved through settlement.

    • Construction Detour - Expert Investigates Fatal Work Zone Collision

      This bicycle/motor vehicle construction work zone collision resulted in the fatality of the bicycle driver. Liability was established against both the construction contractor and the design engineering firm.

      We determined that the collision occurred when the bicycle driver, while riding on a long-established pedestrian/bike path adjacent to a 4-lane thoroughfare, and upon entering the construction work zone, traveled into the oncoming motor vehicle travel lane and was struck by an automobile.

    • Construction Signage - Expert Investigates Single-Vehicle Crash in Work Zone

      This single-vehicle construction work zone collision resulted in serious injury to a passenger. Liability was established against both the construction contractor and the construction inspection firm.

      We determined that: the collision occurred due to the car traveling at high speed and the road surface changing from paved to dirt/gravel as a result of construction activity; the crash occurred within a long-term construction work site; the only construction sign encountered by the driver in his approach to the work site was a Road Work Ahead sign; the street where the work was underway was used as a “cut through” by non-local traffic; the persistent high-speed non-local traffic through the construction site was dangerous to both the construction workers and the traffic; the contractor and the construction inspection firm were aware of, or should have been aware of, the speeding through-traffic prior to the collision, but made no change to the traffic control plan. Based on the facts and in accordance with standards for work zone traffic control, our expert opined that the contractor and the construction inspection firm: should have taken effective steps to detour the non-local traffic; and that the failure of the contractor and the construction inspection firm to employ reasonable and established measures to effectively close the street under construction to through traffic was improper and a substantial cause of the collision and resulting injury. The case settled during mediation.

  • Fatal, Hit-Pedestrian, Night Time Collision
    • Fatal, Hit-Pedestrian, Night Time Collision

      This is a fatal, hit-pedestrian, night time collision. The pedestrian walked in front of a SUV that pulled into the middle lane to make a left turn and then out in front of a car passing the turning SUV. We reconstructed the events of the collision and determined that the pedestrian walked out in front of the driver within the driver’s reasonable perception reaction time. The driver did not have enough time or distance to avoid collision. The cause of this collision was the pedestrian walking out in front of the driver. The driver’s actions were not improper in a manner that was a cause of the crash. The case settled at mediation.

    • 56 vehicle collision, truckers claimed winter conditions occurred suddenly

      This fifty six-vehicle collision occurred under winter conditions. Truck drivers claimed heavy snow conditions occurred suddenly.

  • Tree Struck by Vehicle, Pedestrian Struck by Tree
    • Tree Struck by Vehicle, Pedestrian Struck by Tree

      A pedestrian was injured on an early winter morning when a tree that had fallen onto the roadway was struck by a passing vehicle and pushed onto the pedestrian. The tree fell as a result of extensive decay in the lower portion of the trunk on the side of the tree facing the road.

      Robson Forensic highway engineers addressed tree placement with regard to right-of-ways; our dendrologist addressed the rate of decay and deterioration of the tree; and our facilities engineer, Brian O’Donel, addressed the standard of care for the private property owner inspecting and maintaining buildings and grounds, including trees and tree removal.

      Based on the tree’s rate of decay and the applicable standard of care for maintaining facilities, Brian was able to establish that the property owner knew, or should have known that the tree was in a dangerous condition for over a year prior to its falling. The property owner violated property maintenance standards and local codes when they failed to address the unsafe condition, and this violation was a cause of the pedestrian’s injury.

      This case settled favorably for our client.
