ProfessionalSynopsis

A Transportation Engineer for HDR's Orlando Traffic Operations Department providing strong technical support on a variety of traffic operation projects as well as urban and regional planning projects. Diverse experience consists of preparing Corridor feasibility studies, Traffic and Revenue studies, Operational studies, PD&E studies and Long-Range Transportation Initiative studies. Major emphasis of these studies requires the development and calibration of multi-modal and travel demand models with the production of alternative analyses and travel demand forecasts. Specific project experience includes:

WDW Subarea Model and Master Plan. This project involved the development of a peak hour/multimodal model for the Walt Disney World area. This challenge incorporated Disney's transit system such as their monorail system, 300+ bus fleet, and water taxi service. Responsibilities involved development of future highway and transit demand in the Walt Disney World area and determine future transportation needs through the developed model. 

OOCEA 2025 Long-Range Master Plan. The Master Plan involved developing a strategic initiative where policies and potential projects can be identified for the next 25 years. Tasks involved in looking at local and regional area needs and developing feasible alternatives which looked at freight, park and ride/transit facilities, various toll pricing techniques such as congestion, incentive, and value pricing, and other markets that are not limited to traditional transportation alternatives.

WDW On-Site Transportation Alternatives. The alternatives of this project were developed based on Disney's 2020 land use program. Alternatives involved individual or combinations of an expanded bus fleet, additional monorail lines, and personal rapid transit technology. Tasks involved in providing Measures of Effectiveness (MOE's) in consideration of a viable alternative.

OOCEA Traffic & Revenue Consultant's Annual Report. This report provides traffic and revenue projections of all existing main line toll plaza's of the Expressway Authority's system. Projections are provided with a developed traffic and revenue model that involves yearly maintenance and calibration.

1998 OOCEA Model Validation Report. This report documents the procedures and efforts to validate the OOCEA Traffic and Revenue Model. Tasks include in validating socioeconomic data, incorporating data into the travel demand model, and performing statistical measures to ensure the validity of the model.

SR 436 and Interstate 4 HOV/HOT Lane Concept Study. The study focused incorporating High Occupancy Vehicle lanes and/or High Occupancy Toll lanes on these existing facilities. The analysis involved developing a new element in the travel demand model to evaluate these alternatives. Preliminary traffic and revenue estimates were developed as a part of this effort.

OOCEA System-Wide Origin and Destination Survey. The extensive data collection effort of 3 major limited access facilities located in Central Florida. In this coordination effort, over 180,000 surveys were delivered within a two-week period. Key efforts included large amounts of data reduction organized for travel demand model implementation.

Goldenrod Road Design Traffic. A new 4-lane arterial allowing an additional access point to the Orlando International Airport. Project work included developing travel demand forecasts from validated traffic and revenue model and alternative evaluations of a future interchange. As a result of this project, preliminary revenue forecasts and toll sensitivity analyses were also required.

SR 408 Design Traffic. A 10-mile section of a 22-mile corridor was evaluated for future travel demand. Parallel facilities, intersections, and connecting feeder roads were operationally evaluated. Alternatives such as CD concept, addition/removal of interchanges, and the improvement of the Main Line Toll Plaza (An electronic and manual toll collection facility) were also analyzed.

WDW Cast Charette. This was a public forum of Disney professionals where infrastructure, environmental, regional transportation programs, labor initiatives, and transportation demand management issues were discussed. Tasks involved preparation of all material discussed in a report format.

SR 429- Part C Design Traffic. A new 4-lane limited access toll facility which involved in the preparation of future demand forecasts to the General Engineering Consultant. Duties included a subarea model validation of the study area and providing traffic and revenue estimates for the corridor.

Celebration Traffic Study. A Disney residential community with a large-scale development program. Responsibilities were to incorporate development program into the WDW Subarea Model. Traffic forecasts were developed and transportation improvements were recommended for the study.

Kennedy Boulevard Design Traffic. This was a roadway conceptual analysis study, which involved in the future condition need of the existing facility. Model calibration, land use comparisons, traffic forecasts, and recommended corridor and intersection configurations were developed as a part of this study.

SR 436 PD&E Study. This was a corridor planning study conducted by the Florida Department of Transportation. Responsibilities included development of design traffic forecasts, and evaluation of multimodal improvement alternatives.

He has current knowledge of the application of various software packages: Viper, Tranplan, Highway Capacity Software (HCS), TRANSYT 7F, CORSIM, GIS-Arcveiw.
