COLLISION RECONSTRUCTION & SIMULATION

Built for Complex Claims & Litigation from Scene to Testimony

At Collision Analytics, our ACTAR-accredited accident reconstruction experts develop opinions grounded in accepted forensic methodology and built to withstand scrutiny in depositions, trials, and claim reviews.

Decades of experience in law enforcement, collision reconstruction, and instruction at Northwestern University inform our approach. We apply that experience to every case, analyzing complex data and developing clear, well-supported findings.

Conclusions you can rely on.

We Own the Entire Investigative Lifecycle

At Collision Analytics, we support complex transportation, personal injury, and insurance matters from the first call through final resolution. In doing so, we operate as a single, focused firm with the processes, technology, and expertise to manage the entire investigative lifecycle in-house.

By handling critical processes internally, delays are reduced, and handoffs are minimized. In addition, this approach protects the integrity of evidence throughout the investigation. As a result, analytical consistency improves, and investigations remain aligned with the timelines that matter to attorneys, claims professionals, and fleet operators.

Whether a matter requires early case evaluation, mediation support, or expert testimony at trial, the objective remains the same - to provide clear answers and dependable analysis when important decisions must be made.

Expertise That Supports Critical Decisions

Accident reconstruction expert inspecting real-world evidence.

Effective collision analysis goes beyond software models and data interpretation. Instead, it relies on investigators who understand how real-world collision dynamics and evidence behave from the scene through litigation.

Drawing on field investigation experience and advanced reconstruction methods, our accident reconstruction experts interpret complex evidence, vehicle dynamics, electronic data, and scene documentation. In turn, this analysis connects technical findings directly to the questions attorneys, claims professionals, and fleet operators need answered.

When decisions carry significant financial and legal consequences, clarity and defensibility matter as much as technical accuracy.

Early Intervention That Protects Time-Sensitive Evidence

Time drives exposure in serious collision matters. Critical evidence at a scene can disappear quickly as vehicles move, road conditions change, or electronic data is overwritten. Early intervention is critical to preserving perishable evidence and maintaining the integrity of the investigative process.

To address this, our team combines law-enforcement investigative experience with rapid-response capabilities. We secure and preserve perishable evidence early on, applying structured scene documentation and preservation methods, such as vehicle inspections and electronic control module data downloads. In addition, these processes ensure that critical evidence is collected accurately and remains defensible.

Through early involvement, we help preserve the evidentiary record, reduce uncertainty, and establish a stronger investigative foundation for the life of the case.

Experience Across the Full Spectrum of Collision Types

Harley Davidson motorcycle collision investigation and reconstruction services.

Our investigators handle cases involving passenger vehicles, motorcycles, pedestrians, heavy vehicles, and complex commercial fleet operations. Each collision type introduces different vehicle dynamics, regulatory considerations, operational practices, and evidentiary sources, requiring the use of appropriate investigative methods. As a result, each investigation requires methods tailored to each case-specific circumstance.

Those methods are applied to ensure complete, accurate, and defensible analysis. Whether supporting litigation, insurance claim evaluation, or major commercial transportation matters, our work aligns with the complexity and exposure inherent in each matter.

We offer an array of services including rapid response investigation, forensic documentation, electronic collision data collection, video analysis, collision reconstruction & simulations, light vehicle investigations, motorcycle investigations, heavy vehicle and commericial fleet investigations, expert witness testimony, and professional training.

What Our Clients Are Saying

Bryce B., Heavy Vehicle Trucking Expert

Andrew is a true professional who is a master in his craft. After 25 years in law enforcement, I’ve yet to meet anyone as knowledgeable and detailed in his reconstruction work as Andrew. He is THE subject matter expert, and his work is a true passion not just a paycheck. You would be well served to employ Collision Analytics for your training or reconstruction needs.

Seth H., Attorney

Andrew’s done great expert work that’s facilitated settlement in my cases. Very detail oriented.

Dan W., Attorney

I learned everything I know about major crash reconstruction by preparing for trial with Andrew Thomas. As a former prosecutor who tried many vehicle crash and death cases, there was nothing better than having Andrew as an expert witness to inform the judge or jury about how the scene came to be, based on physics and his calculations. Andrew was great to work with, was a great expert witness on the stand, and was always just a phone call away to answer any questions that came up about a reconstruction. I highly recommend Andrew and his abilities in this field.

Daniel D., Attorney

My firm retained Mr. Thomas as an expert accident reconstruction expert in a difficult “phantom” hit and run case in which the insurance company steadfastly refused to cover the incident prior to us filing suit. Mr. Thomas’s report was as thorough and comprehensive as possible given the facts of the case. Mr. Thomas outworked the insurance company’s reconstruction expert by a mile, who is a P.E. with a large forensic engineering firm in the area. Mr. Thomas was a fantastic witness at the deposition and did not back down against a very experienced and aggressive opposing counsel.

Most reconstruction experts do not have years of experience in the courtroom as a law enforcement officer, and they would not have handled this deposition with the strength and grace Mr. Thomas demonstrated. The insurance company initiated settlement discussions soon after Mr. Thomas’s deposition, and through negotiation, we were able to reach a favorable result for our client.

I do not think this would have been possible without Mr. Thomas’s dedicated work on the case. Finally, Mr. Thomas is friendly, professional, and always available to help his clients in any way that he can. I endorse Mr. Thomas without reservation.

Albert W., Attorney

Andrew Thomas makes complicated data understandable. I am glad I retained his services on behalf of my client.
