DAVID HOOK, P.E.
David Hook is a traffic engineer and transportation planner who has spent the vast majority of his career in all aspects of traffic engineering and transportation planning. He has performed model development and implementation, evaluation and operation of traffic signal systems, ITS and traffic engineering.
SELECTED PROJECT EXPERIENCE
Transportation Planning and Model Development
Mr. Hook’s particular expertise is in transportation modeling and he has developed models all over the United States using Tmodel, Tranplan, Minutp, UTPS, QRSII and others. Mr. Hook is also the author of a new transportation planning model, AVPlan, a model that runs as a shell under ArcView.
Northern Colorado Springs Model Development. Mr. Hook worked with the City of Colorado Springs to develop a transportation planning model for the northern part of Colorado Springs. This model encompassed a planning area of 10 square miles and evaluated land use and roadway geometrics. The model incorporated a four-step planning model and was integrated with ArcView.
Town of Gilcrest. David Hook prepared the transportation element in the Town of Gilcrest Comprehensive Plan update that is currently under final development. This update evaluated the roadway network within the Town of Gilcrest and provided potential roadway improvements to improve the transportation network within the town.
City of Colorado Springs Traffic Operations Center. Mr. Hook is a project manager on a project for the City of Colorado Springs, Colorado, Traffic Operations Center (TOC) to provide a framework for evaluation of the center. He has performed a comprehensive literature search to determine the latest “state-of-the-art” in TOC evaluations. He has created a framework by which the TOC could perform evaluations of their system. Mr. Hook also prepared grant applications with associated benefits of the TOC for the Pikes Peak Area Council of Governments (PPACOG) for $30 million in funding. The next phase of the project will be to model incidents and delay along freeways and major corridors to provide actual benefits of the system.
Colorado Springs Congestion Improvement Program Project Evaluations. Mr. Hook performed extensive evaluations to develop costs and benefits of major construction projects in Colorado Springs, Colorado. The purpose of the project is to provide a list of projects to present to the voter’s in 2003. The project involved field visits, traffic data collection, modeling of the intersection within Synchro, sketches of the proposed intersections improvements and cost estimates.
City of Greenwood Village Traffic Signal Assistance. Mr. Hook serves in an on-call capacity to provide traffic signal system assistance to the City of Greenwood Village, Colorado. The City does not have staff to evaluate signals as to appropriate cycle length, phasing, splits and offsets. Mr. Hook provides these services to the City of Greenwood Village on an as-needed basis.
City of Fort Collins Traffic Signal System Retiming. Mr. Hook was project manager for a comprehensive signal retiming for the City of Fort Collins, Colorado. The project involved creating new signal timing plans for the AM, midday and PM peak at over 250 intersections within the City. The project also involved evaluating the pedestrian crossing times at each approach and updating these minimums in the controller. The signal timing plans were generated using Synchro, Passer, and Transyt. A comprehensive evaluation of the system was then performed to show the improvements to the system and associated reduction in delays, travel times, stops and emissions. The methodology to determine which signals should be tied together was presented to ITE in 1999.
Colorado Department of Transportation On Call Traffic Engineering Services, Region IV. Mr. Hook has been a project manager for two on-call projects for the Colorado Department of Transportation Region IV. The projects deal mostly with safety improvements at various intersections within the region and the evaluation of new traffic signals. Some work has been performed in developing methodologies to evaluate the impact of not placing signals on the system.
Operations research of leading and lagging left turns. Project Manager for a massive research project conducted for the Arizona Department of Transportation. The research evaluated the effectiveness of leading or lagging left turn phasing. Three research test beds were implemented in Glendale, Tempe and Mesa, Arizona. To evaluate the most effective phasing at each intersection, a computer program was developed which tested leading or lagging signal timing for each approach of each signalized intersection. The results of this research were published in Transportation Research Record 1421.
Comprehensive Signal Timing, Scottsdale, Arizona. Mr. Hook was a project engineer for a comprehensive signal retiming effort in the City of Scottsdale, Arizona. The project involved retiming the approximate 140 signals within the City.
PASSER II Training, Maricopa County, Arizona. Developed and led a PASSER II training session with Maricopa County Department of Transportation (McDOT) traffic engineering staff. The training showed the city staff how to code the PASSER II software, how to run the program and interpret the results.
Traffic Signal Timing and ITS
North Avenue Corridor Timing; Grand Junction, Colorado. Developed a signal timing plan for North Avenue in Grand Junction, Colorado. The project involved developing signal timing for AM, midday and PM peak periods for an 11 signal corridor. The project also included the training the city staff on signal timing. TEAPAC was utilized to code the corridor which was then optimized with PASSER and TRANSYT-7F.
City of Scottsdale, Arizona signal timing; Scottsdale, Arizona. Project Engineer for a comprehensive retiming of the City of Scottsdale, Arizona’s INTERTIE signal system. Traffic signal timing plans were implemented at 104 intersections for AM, PM, midday and off-peak periods. The central COMPUTRAN system with FORCAST signal timing software was utilized to develop and implement signal timing plans to the local controllers.
Operations research of leading and lagging left turns; Glendale, Tempe and Mesa, Arizona. Project Manager for a massive research project conducted for the Arizona Department of Transportation. The research evaluated the effectiveness of leading or lagging left turn phasing. Three research test beds were implemented in Glendale, Tempe and Mesa, Arizona. To evaluate the most effective phasing at each intersection, a computer program was developed which tested leading or lagging signal timing for each approach of each signalized intersection. The results of this research were published in Transportation Research Record 1421
City of Fort Collins Signal Retiming Project. Project Manager for a comprehensive traffic signal retiming project for the City of Fort Collins. The project included data collection, signal timing modifications and implementation. Every traffic signal within the City was evaluated for pedestrian walk and clearance times. A massive traffic signal retiming was prepared using Synchro in combination with Transyt-7F and Netsim. These were implemented into the City's traffic signal system. A comprehensive before-after travel time and delay analysis was performed using real data from travel time and delay studies.
Lakewood Signal System Design; Lakewood, Colorado. Project Engineer for the Advanced Traffic Management System in Lakewood, Colorado. The project evaluated alternative system types (distributed, hybrid, central control), alternative communication systems and prepared bid documents. After the initial review of several systems in California, Colorado, Texas and Toronto, the project team provided an informational seminar to local traffic engineer’s on the results of the field visits.
Fortuna TI Interchange area timing; Yuma, Arizona. Project Manager to develop a signal timing strategy for the Fortuna TI in Yuma, Arizona. This location has a typical on-off ramp at the interchange, but also frontage roads on each side. The timing plan was developed so that the heavy through and turning movements would not be delayed by other signals once given a green for their movement.
PASSER II Training; Maricopa County, Arizona. Developed and led a PASSER II training session with Maricopa County Department of Transportation (McDOT) traffic engineering staff. The training showed the city staff how to code the PASSER II software, how to run the program and interpret the results.
