Bryan Allery is a founding Principal of DiExSys and has over 25 years of experience in transportation engineering, including 7 years at CALTRANS and 17 years at CDOT.  Bryan is a nationally recognized expert on traffic records, accident analysis, and safety program management. He has extensive experience in developing Safety Management Systems and related computer programming.  He is a highly experienced transportation engineer in the areas of design, construction management, materials, geometric design, and traffic engineering. He has served as a research study panel member at the National Cooperative Highway Research Program (NCHRP).  Bryan, together with Dr. Jake Kononov, has co-authored a number of research papers on road safety.  

His experience at the Colorado DOT included responsibility for the conceptual development and implementation of strategies and programs to improve highway safety.  He managed planning and budgeting of statewide safety improvement programs (HSIP). Bryan oversaw the assessment of safety needs and recommendations for safety improvements on the statewide resurfacing program (budget $100,000,000), reconstruction, realignment, and major widening projects. He managed the process of optimizing investments into safety improvements to maximize program‑wide accident reduction within the constraints of available budget. 

Bryan was responsible for providing expert advice and supporting analysis on safety related matters to six engineering regions. He analyzed statewide safety needs and provided timely input to six engineering regions to ensure early consideration of safety in the planning, scoping, design, construction, and maintenance of transportation facilities. He is a Registered Professional Engineer in Colorado and California.
