Company Principals
J. Douglas Hunt P.Eng. holds a bachelor's degree in Civil Engineering from the University of Alberta, as well as a doctorate degree in Urban Architecture from the University of Cambridge, England. He is an internationally recognized and widely published expert in land use and transport interaction modelling, having over 25 years of experience in transportation demand modelling and land use transport interaction modelling in Europe, the United States and Canada. His special expertise is in the design and calibration of these models, developing them so that they can be used to examine policy alternatives involving such things as infrastructure development, alterations in land use regulations, changes in transportation conditions (including operations, tariffs and user costs) and new economic and fiscal arrangements. In addition to his role in HBA Specto Incorporated he is a professor of Transportation Engineering at the University of Calgary.
John Abraham P.Eng. holds a bachelor’s degree in Electrical Engineering from the University of Calgary, as well as masters and doctorate degree in Civil Engineering from the University of Calgary. He has almost 20 years of experience in developing and calibrating spatial economic and travel demand models. John has expertise in developing and calibrating models to provide computer simulations that are both accurate and practical for analyzing policy and scenarios. He is an expert on survey techniques for understanding preferences, measuring tradeoff rates and predicting behaviour.
Alan Brownlee P.Eng. holds a bachelor’s degree in Civil Engineering and a doctorate degree in Applied Science (Transport Planning) from the University of Newcastle upon Tyne, England. He has over 35 years of experience in both Canada and the UK in developing and applying travel demand models, particularly using EMME. He specializes in the areas of travel forecasting, assessment of transportation needs, and development of transportation plans for urban areas. Prior to joining HBA Specto Incorporated he worked in increasingly responsible positions for the City of Edmonton for over 27 years, retiring as Director of Evaluation & Monitoring for the Transportation Planning Branch.
Transportation Modelling Specialists
Kevin J. Stefan, P.Eng. graduated in 2000 from the University of Calgary, receiving a B.Sc. with distinction in Civil Engineering with minors in Transportation Engineering and Entrepreneurship and Enterprise Development. He has eight years of transportation engineering experience, the majority (6.5 years) with the City of Calgary as a Transportation Engineer in the Forecasting division of Transportation Planning, where he worked primarily on model development work for the Calgary EMME model, including the data preparation, estimation, calibration and validation of a tour-based micro-simulation commercial vehicle model.
Dimantha I. De Silva, has over six years of transportation engineering experience both in Sri Lanka and in Canada in the area of public transportation, developing and calibrating transportation demand models and spatial economic models for land use forecasting. He is an expert on applications of cluster analysis, demand model application and model scripting and integration using CUBE software. Since 2006 has been involved in several projects in HBA Specto Incorporated, in transportation and spatial economic land use models development, design, calibration, initially as a contractor and since 2009 as an employee.
Geraldine Fuenmayor, is an urban and transportation planner, with experience in the application of transportation and land use forecasting models in the evaluation of transportation needs, and in the evaluation of land use and transportation projects and policies. Project responsibilities have been oriented to work with transportation models, land use and transportation geo-databases for the models, including transit routes inventories, traffic and urban variables databases, most of the time in the context of a transportation-land use integrated modelling approaches for local, master and regional plans and studies.
Mina Hassanvand, E.I.T., holds a Bachelor of Science in Civil Engineering from the University of Calgary since 2009. Her project is related to the factors affecting utility of passenger modes in Calgary. She is working as an Engineering Analyst at HBA.
