Joe Castiglione is a senior consultant at RSG, and has served for over 13 years in a variety of technical roles on travel forecasting and transportation planning projects both as an independent consultant and in the public and private sectors. He has managed the development, application, and refinement of state-of-the-art, activity-based travel demand forecasting models, and has extensive experiencing linking these demand models with advanced traffic microsimulation models.
Dr. Xuesong Zhou is currently an Assistant Professor in the Department of Civil and Environmental Engineering at the University of Utah. Prior to joining the University of Utah, he served as a Traffic Data Architect and Senior Software Engineer at Dash Navigation, Inc, designing and developing the first commercialized internet-connected GPS navigation system in the U.S. He is also the co-inventor of Key2SafeDriving technologies, which has been reported by more than 300 media outlets including New York Times, Wall Street Journal and National Public Radio. Dr. Zhou's research interests include dynamic traffic assignment, traffic estimation and prediction, large-scale routing and rail scheduling. He has been assisting the Federal Highway Administration (FHWA) to develop and provide technical support for large-scale simulation-based dynamic traffic assignment systems for the past 10 years. Dr. Zhou's research work has been published in highly cited scholarly journals such as Transportation Research Part B, Transportation Science, IEEE Transactions in Intelligent Transportation Systems. He is the Co-Chair of the IEEE ITS Society Technical Committee on Traffic and Travel Management and serves as a Committee Member for TRB Committee on Transportation Network Modeling (ADB30).
David Stanek, P.E., is an Associate Engineer with Fehr & Peers' Roseville office and has over 12 years of transportation engineering experience. With his experience at Caltrans District 3, Mr. Stanek is familiar with the project development process and traffic operations analysis as applied to freeway improvement projects including interchange reconstruction, HOV lanes, and ramp metering. He has expertise in applying arterial corridor analysis (Synchro and Transyt7F) and traffic simulation software (SimTraffic, CORSIM, VISSIM, and Paramics) to analyze complex traffic operations such as single-point interchanges, roundabouts, and bus rapid transit operations. Mr. Stanek serves as a company-wide resource for traffic operations analysis and teaches training courses on intersection analysis and roundabouts.
Mr. Griesenbeck has 25 years of experience in transportation planning and travel demand modeling, working directly for public agencies (City of Hayward, CA; Sacramento Area Council of Governments) and as a consultant (Wilbur Smith Associates' San Francisco office; DKS Associates' Sacramento office). He is currently the Principal Transportation Analyst for the Sacramento Area Council of Governments, the MPO for the six-county Sacramento region, where he leads the transportation forecasting and analysis team, and transportation monitoring team. He led the development of SACOG's activity-based travel demand simulation model (SACSIM), the first such regional model to be based on parcel-level land use data. He participated in a statewide MPO effort to support and advise California Air Resources Board in its implementation of SB375, the land use / transportation portion of the state's greenhouse gas reduction policy. SACSIM was the basis of the travel demand analysis and forecasts for the adopted 2008 and 2012 long range transportation plans, as well as its requisite air quality conformity analysis for the plan. The 2012 LRTP was the first SB375 "Sustainable Community Strategy" for SACOG. He has served as an advisor on two National Cooperative Highway Research Program panels, and is a member of the Transportation Research Board Travel Demand Forecasting Committee.
Dr. Papayannoulis has 27 years of experience and recently joined IBI as a Regional Manager for Transportation Planning. Previously, Dr. Papayannoulis was a Principal and the New York Office Travel Demand Forecasting Regional Manager for Cambridge Systematics (CS). From 1990 to 2008, Dr. Papayannoulis worked at Urbitran Associates, Inc. (UAI), where as a Senior Vice President he directed the Transportation Modeling group. Dr. Papayannoulis' areas of expertise include travel demand forecasting, traffic operation simulation, database management systems, safety, system performance measures, software development and Geographic Information Systems (GIS). Dr. Papayannoulis' technical knowledge and in-depth understanding of the issues related to traffic simulation has engaged him in the development of numerous complex models, including NYCODT's Manhattan Traffic Model, where a platform supporting corridor management planning, design, and operations based on a multi-resolution model (interfacing travel demand models, mesoscopic simulation models, and microscopic simulation models) was developed. He has worked for Federal, state, regional, and local agencies and he has taught transportation courses at both Polytechnic University and City College of New York.
