For more than forty years, Dr. Fazil T. Najafi has worked in government, industry and education. He earned a BSCE in 1963 from the American College of Engi¬neering, in his place of birth, Kabul, Afghanistan, and since then came to the United States with a Fulbright scholarship earning his MS in civil engineering in 1972 and a Ph.D. degree in transportation in 1977. His experience in industry includes work as a highway, structural, mechanical, and consultant engineer and construction manager for government groups and private companies. Najafi went on to teaching, first becoming an assistant professor at Villanova University, Pennsylvania in 1977, a visiting professor at George Mason University, and then to the University of Florida, Department of Civil Engineering, where he advanced to associate professor in 1991 and then full professor in 2000 in the Department of Civil and Coastal Engineering. He has received numerous awards including a scholarship award (Fulbright), teaching awards, best paper awards, community service awards, and admis¬sion as an Eminent Engineer into Tau Beta Pi. His research on passive radon-resistant new residential building construction was adapted in HB1647 building code of Florida Legislature. Najafi is a member of numerous professional societies and has served on many committees and programs, and continuously attends and presents refereed papers at international, national, and local professional meetings and conferences. Lastly, Najafi attends courses, seminars and workshops, and has developed courses, videos and software packages during his career. His areas of specialization include transportation planning and management, legal aspects, construction contract administration, and public works.

A Cost Effective Methodology for Pedestrian Road Crossing for Developing CountriesABSTRACT:Pedestrians travel holds an important aspect in the transportation trip mode, therefore research onpedestrian crossing is necessary and important step to select pedestrian facilities. Delay is animportant measure of effectiveness in traffic studies. Much research has been conducted onvehicles delays but the research on pedestrian delay is much less. However, mostly commonused delay estimation methods and models are derived from Highway Capacity Manual and arerelatively simple, without enough attention on the effect of platoon. The aim of this paper is to present a low-cost methodology for the selection of proper pedestriancrossing facility by anticipating pedestrian delays at interrupted and uninterrupted flow and tocorrelate the pedestrian delays with level of service based on six levels which are ranked usingthe human' perceptions of comfort, safety and psychological limitation as well as acceptabledelay. This paper focuses on the application of statistical distributions to model traffic andpedestrian flows and Monte Carlo techniques to simulate traffic and pedestrians, and discusseshow to create a tool in order to quantitatively rank which pedestrian facility is appropriate forparticular situation. Initially pedestrian delay can anticipate at un signalized intersection. If thepedestrian delay found to be more in uninterrupted flow, then signalized facility will besimulated. Later, effect on vehicle delay at signalized intersection will be simulated. . Finallydelay simulation outputs will be used for the selection of pedestrian facility either un signalizedcrosswalk, signalized cross walk or grade separated pedestrian facility.
