About Highway Design Evaluations

"A deep understanding of highway design projects."

EES provides expert litigation support for traffic and transportation matters. With decades of experience, we support legal professionals nationwide. Our engineers have worked on various transportation projects in Southern California, including street rehabilitation and new roadways.

We have designed traffic signals in cities like Fontana and Redlands. Our highway design expertise allows us to objectively evaluate accident cases. We help clients navigate design immunity and litigation against public agencies. EES prides itself on delivering quality support based on expert witness experience and scientific objectivity.

Highway Design & Operations

Roadway Design Defects

Roadway design defects are flaws in the planning and construction of roads that can lead to unsafe driving conditions. These defects can include poor road layout, inadequate signage, insufficient lighting, or faulty drainage. Identifying and addressing these issues is crucial for road safety, as they can increase the risk of accidents and injuries.

Malfunctioning Traffic Signals

Malfunctioning traffic signals are traffic lights that don't work correctly, causing confusion and increasing the risk of accidents. This can include lights that are out, stuck on one color, or showing conflicting signals. Prompt repair is needed to ensure safe and smooth traffic flow.

Delineation & Signing Defects

Delineation and signing defects make it difficult for drivers to understand road layouts or follow traffic rules. This can include faded lines, missing signs, or incorrect information, leading to confusion and potential accidents. Fixing these issues is essential for safe driving.

Circulation Evaluations

Circulation evaluations are assessments of how traffic moves through a specific area, like a neighborhood or shopping center. These evaluations help find problems like traffic jams and unsafe intersections, and suggest improvements for smooth and safe traffic flow for drivers and pedestrians.

Parking Lots & Driveways

Parking lots and driveways are areas where vehicles are parked or enter and exit properties. Design and maintain these areas well to ensure safe and efficient vehicle movement, prevent accidents, and make it easier for drivers to find parking and access buildings.

Street Lighting & Illumination Studies

Street lighting and illumination studies examine the effectiveness of lighting on roads and streets. They make sure there is enough light at night for drivers and pedestrians to see well, reducing the risk of accidents and making it safer.

Highway Drainage Defects

Highway drainage defects are problems with the systems that remove water from roads. Poor drainage on highways can lead to water pooling, making the road slippery, causing hydroplaning, and damaging the road. This can lead to accidents and unsafe driving conditions.

Traffic Studies

Traffic studies analyze how vehicles move on roads to identify issues like congestion, accidents, and delays. They involve collecting data on traffic volume, speed, and patterns during different times of the day and in various conditions. These studies help planners and engineers design better roadways, optimize traffic signals, and implement measures to reduce congestion and accidents.

Clear Zone Encroachments

Clear zone encroachments occur when objects like trees, signs, or poles are too close to the road, creating hazards for vehicles that might veer off. Removing these obstacles improves safety by providing a clear area for drivers to recover control if they leave the roadway.

Sight Distance Defects

Sight distance defects are issues that block a driver's view of the road ahead, such as curves, hills, or obstructions like trees and buildings. These defects make it difficult to see oncoming traffic or road signs, increasing the risk of accidents. Fixing these issues improves safety by ensuring drivers have a clear view.

Radar Speed Studies

Radar speed studies measure how fast vehicles are traveling on a road using radar technology. These studies help identify speeding issues and determine if speed limits need to be adjusted to improve safety for drivers and pedestrians.

Temporary Traffic Control

Temporary traffic control involves setting up signs, barriers, and signals to safely guide drivers through construction zones or around road incidents. This helps prevent accidents and ensures smooth traffic flow during temporary road disruptions.
