Paul Basha, PE, PTOE
EXPERIENCE
Summit Land Management offers professional traffic engineering services led by Paul Basha, PE, PTOE. Mr. Basha has been a traffic engineer for over 52 years, including 42 years in Arizona. His extensive career includes 22 years with the City of Scottsdale, and 24 years as a consulting traffic engineer.
He continues to serve as a Faculty Associate at Arizona State University, where he has taught undergraduate and graduate traffic engineering courses for 27 of the past 31 years, including the summer of 2026.
As a consultant, Paul has completed traffic impact analyses for more than 250 proposed developments, as well as parking analyses for over 50 existing or proposed sites. He has a distinctive reputation for his thorough analyses and ability to creatively resolve complicated transportation safety and traffic flow problems.
He has been a valuable resource analyzing and solving transportation problems as a consultant hired by numerous municipalities including Avondale, Carefree, Gilbert, Maricopa, Mesa, Phoenix, Scottsdale, Surprise, and Tempe.
EXPERTISE
Among Paul’s extensive knowledge of numerous aspects of traffic engineering, Paul is one of three dozen nationally recognized experts in trip generation analyses for proposed developments.
Summit Land Management recognizes that traffic and parking are critical factors when determining project feasibility. Paul frequently advises developers during their preliminary consideration of properties to determine whether a proposed land use or size is feasible.
Summit Land Management has developed quasi-automated calculation techniques that allow efficient evaluation of potential land uses and development sizes based on projected trip generation and parking demand.
Paul is an exceptional data analyst and report writer, as well as much more. His reports provide detailed technical analyses and brief Executive Summaries suitable for elected officials and laypeople to understand. Paul embraces projects entirely and is instrumental in strategizing meetings and public hearing presentations with elected and appointed public officials.
Summit Land Management recognizes that our data and analysis are an important part of the review and approval process. We further understand that the trip generation or parking demand, in particular, can become adversarial. Neither calculation is rudimentary. Paul understands that these two aspects of planning developments are crucial to determining if a potential project is likely to receive town, city, county, or state approval.
The ultimate goal of the review process is the jurisdiction approval of a community benefit, provided by a developer, that is financially viable. This is the focus of every Summit Land Management traffic or parking analysis. His 52-year professional history as a public agency traffic engineer, a consulting traffic engineer, and a part-time traffic engineering university instructor has given him the ability to concisely and successfully explain traffic engineering concepts and impacts.
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, in Washington state, he provided analyses for plaintiff litigation against public agencies. This experience proved invaluable in later years in depositions and testimony successfully defending litigation against the City of Scottsdale. As a consultant, Paul was instrumental in producing a low-dollar settlement of a large-dollar fatal-collision claim against a shopping center owner. Paul has also recently been involved in litigation assisting two private property owners to receive favorable settlements from municipalities.
Paul serves as Faculty Associate with Arizona State University (1996 to 2002 and 2006 to 2026) instructing undergraduate and graduate traffic engineering courses. He also has regularly taught traffic engineering seminars for Maricopa County Department of Transportation employees. More than 80 members of the Arizona Section of the Institute of Transportation Engineers have studied traffic engineering in university courses or seminars with Paul’s direction.
Paul is an active member of both the Institute of Transportation Engineers and WTS, Advancing Women in Transportation.
