One automated system developed by Paul quickly determines the degree of satisfaction of traffic signal and multi-way stop warrant analyses. Because of this programmed system, modifications to the traffic volumes, lane configurations, and speed limits can be instantaneously compared.

Paul has also created calculation methodologies for shared parking models developed by six separate municipal or agency sources. These automated calculations quickly determine required parking space numbers for different land uses and different land use sizes. Paul always recommends the maximum required parking space number as determined from multiple shared parking models. Alternatively, Paul’s analysis process can determine land use and land use size options compatible with the available number of parking spaces. This technique has determined the proper parking space number for several proposed or renovated developments including both resort properties and commercial properties.

Another of these automated analyses is a collision examination system utilizing the Arizona Department of Transportation published statewide collision data. This process quickly identifies the collision manner, vehicle travel directions, vehicle turning movements, driver violations, and injury severities at specific locations. These analyses identify the reasons and driver behaviors that resulted in the collisions, and are highly beneficial in determining mitigation measures.

Paul’s evaluations are data-intensive to ensure analyses validity and future proper operation of street systems and developments. Paul’s approach is to be highly collaborative with clients, other consultants, and jurisdictions to ensure the most successful developments and communities possible.

Paul is a nationally recognized trip generation expert. He served on both the technical and review committees for the 5th Edition of the Parking Generation Manual, the 10th and 11th editions of the Trip Generation Manual, and the 3rd Edition of the Trip Generation Handbook. Paul was personally invited by the Trip Generation Handbook, 3rd Edition review committee chair to join him in presenting the extensively revised Handbook immediately prior to its publication at the 2014 International Conference of the Institute of Transportation Engineers.

Paul is also available for expert witness testimony in litigation involving traffic collisions. His preference is to assist the defense of public agencies. Early in Paul’s traffic engineering career, he provided analyses for plaintiff litigation resulting from traffic collisions against public agencies. This experience proved invaluable, when he was the Scottsdale Traffic Engineer, in depositions and testimony, while successfully defending similar litigation against the City of Scottsdale. As a consultant more than a dozen years ago, Paul was instrumental in producing a low-dollar settlement of a large-dollar fatal-collision claim against a shopping center owner. Paul was also instrumental in ensuring a proper impact fee assessed by a municipality on a then-recently constructed retail and warehouse facility.

Paul has been since 1996, and continues to be, a Faculty Associate with Arizona State University instructing undergraduate and graduate traffic engineering courses. He also has regularly taught traffic engineering seminars for the Maricopa County Department of Transportation. More than 70 members of the Arizona Section of the Institute of Transportation Engineers have studied with Paul’s direction.

Paul is an active member of both the Institute of Transportation Engineers and WTS, Advancing Women in Transportation.
