- Professor and Transport and Main Roads Chair, 2018-Present, Queensland University of Technology, Brisbane, Australia
- Associate Professor, 2014-2018, University of Nevada, Las Vegas, Nevada, USA
- Director, 2013-2018, Transportation Research Center, University of Nevada, Las Vegas, USA
- Assistant Professor, 2008-2014, University of Nevada, Las Vegas, Nevada, USA
- Senior Professional, 2007-2008, Cambridge Systematics, Oakland, California, USA
Before becoming a university professor at the University of Nevada, Las Vegas (UNLV), I worked for one year as Senior Professional for a major consulting firm, Cambridge Systematics. I worked on multiple projects for clients, including Federal Highway Administration, California Department of Transportation (CalTrans), and local Metropolitan Planning Organizations. Results from my work where used at the operational level to select strategies to deploy intelligent transportation systems throughout the San Francisco metropolitan area. During that time, the work that we did was innovative in terms of using and expanding capabilities provided by Dynamic Traffic Assignment to evaluate multiple intelligent transportation system technologies for a real-work traffic system. The evaluation was performed with the final objective of making decisions that would result in integration of multiple traffic systems and modes of transportation.
Business Intelligence and Advanced Analytics
My major industry experience is a large Business Intelligence project that involved data warehousing, software development, advanced analytics, dashboard implementation, and training to the sponsor/client. I was the principal investigator (PI) for this $US 2.8 million project, and my share was 80%. As the manager and PI for this project, I was responsible for hiring professionals and graduate students, had regular communication with the Front Office of NDOT, provided leadership and guidance to my team, provided high-level recommendations to the project manager at NDOT, and pursued innovation and commercialization of the corresponding technology. Key innovations from this project are listed below, with non-provisional applications for patents filed for the first two innovations:
- A workflow and software system that integrates ESRI ArcMap and Oracle Business Intelligence Enterprise Edition for reporting analytics on interactive maps. Deployed in 2014 and in use since then by the Nevada Department of Transportation.
- A workflow and software system that uses data from the National Bridge Inventory to generate and report color-coded three-dimensional renderings of key bridge elements. Deployed in 2014 and in use since then by the Nevada Department of Transportation.
- A workflow and software system that uses data from the Highway Performance Monitoring System (HPMS) to generate capacity analyses using the Highway Capacity Manual Methodology. The software reports capacities by means of interactive maps, tables, and drilldowns. Deployed in 2016 and in use since then by the Nevada Department of Transportation.
In addition to these key software systems, we designed and deployed a data warehouse, developed and implemented regression models for financial and traffic systems, and developed and implemented hundreds of interactive dashboards. NDOT currently uses these developments and implementations to provide service and save time to hundreds of people throughout the agency.
My second largest project for NDOT involved the design, development, implementation, and testing of a Utility Data Management Software System. This included a geo-spatial database, a web portal for data visualization and management, many feature code libraries for multiple vendors of data collection equipment, and a website for data loading and interaction with external contractors who collect field data. This system was developed and implemented in the first phase of the project with a cost of $US 610,000, and my share was 80%. I was the PI of the project, and responsible for management and major decision making as well as communication with the project champion at NDOT. We currently are working on the second phase of the project, which involves moving the system into production using the servers of the Transportation Research Center at UNLV. This means that for the first time, we are going to be proving cloud service to a state government agency. The cost of this second phase is $ US 130,000, and I am the only faculty working on this project.
My most exciting project that is currently underway involves the design, prototyping, and field test of a couple of traffic safety devices, which I cannot describe in detail because of the intellectual property restrictions by UNLV. A local startup, Rebel Roadway Systems LLC, licensed the technology from the university, and currently is working on commercializing it. UNLV is completing field testing at a local campus roadway facility. In parallel, we are working on optimizing and improving our design as well as adding capabilities for data collection; we also are about to secure resources for major field testing in Las Vegas.
