CE 436 – ROADWAY DESIGN SPRING 2008 January 15, 2008 • Mike Arneson, PE • BSCE 1993 – University of Idaho • Professional Engineer licensed in Idaho, Utah, and Oregon • 13 years with Oregon Department of Transportation • 1 year with Idaho Transportation Department • 2 years in private consulting • Career Highlights • Engineer of record on transportation projects more totaling more than $400 million in value • Urban interchange design experience • Public involvement processes • National Environmental Policy Act (NEPA) experience First time teaching a college course! Who are you?
EXPECTATIONS FOR THIS SEMESTER - My perspective Housekeeping – breaks, etc. Classes that provoke discussion and interaction Provide a broad understanding of roadway design and project development Flexible plan to spend more or less time on topics as needed “Real World” perspective on roadway design and transportation Address your specific interests as much as possible Homework assignments and exams that require technical writing and research Enthusiasm and attendance Office hours? - Your perspective
OVERVIEW OF ROADWAY DESIGN AND ENGINEERING AS IT RELATES TO THE OVERALL TRANSPORTATION SYSTEM How did you get from where you live to this class tonight? How many hours per week do you spend in a car? Walking? On a bike? How many homicides are there in the US each year? How many lives are lost in the US in automobile accidents each year? 3 E’s of transportation safety – What role does transportation play in the economy? 18,000 43,000 education, enforcement, engineering
OVERVIEW OF ROADWAY DESIGN AND ENGINEERING AS IT RELATES TO THE OVERALL TRANSPORTATION SYSTEM What are the major components needed for management of the roadway transportation system? Maintenance, Project Development, Construction Roles that roadway engineering plays in each of these components? Roadway Engineering – the art and science of applying accepted standards and using engineering judgment for the design of roadway facilities. Within Departments of Transportation, Roadway Designers tend to be the hub of the project development process for transportation design projects.
TRANSPORTATION INFRASTRUCTURE – COST – CAREER OPPORTUNITIES The transportation infrastructure consists of many specialized disciplines within civil and other types of engineering. Geotechnical Structural Hydraulic Environmental Traffic Materials (pavements, etc.) Electrical Mechanical Computer/Software Construction Management
TRANSPORTATION INFRASTRUCTURE – COST – CAREER OPPORTUNITIES Roadway Segments Erosion Control Bridges Pavements Retaining Walls Bicycle Signals Pedestrian Storm Drainage Systems Utilities Water Quality Treatment Illumination Signs Intelligent Trans. Systems Striping Aesthetics
TRANSPORTATION INFRASTRUCTURE – COST – CAREER OPPORTUNITIES • Roadway Design typically responsible for: • Roadway Segments • Storm Drainage Systems • Striping • Erosion Control • Utilities • Some Aesthetics • Specifications • Cost Estimating • Others
TRANSPORTATION INFRASTRUCTURE – COST – CAREER OPPORTUNITIES • Cost of Transportation Infrastructure • Responsibility of engineering to make efficient, safe designs • Typically tax dollars are invested in the public transportation system • Design/Construction by DOT staff and/or private consultants • How much does an interchange cost in a rural area? • How much in an urban area? • How much does a signal cost at a single intersection?
TRANSPORTATION INFRASTRUCTURE – COST – CAREER OPPORTUNITIES • Cost of Transportation Infrastructure • Funding Sources • Funding Outlook / Job Security • Roller Coaster • Relationship of transportation investment to economic growth • Politics (Engineers hate this, but it is reality)
TRANSPORTATION INFRASTRUCTURE – COST – CAREER OPPORTUNITIES • Career Opportunities in Roadway Design/Engineering • DOT’s – maintenance, project development, construction • Consulting • Contractors • Larger Cities and Counties • FHWA • Both technical and management career paths are available, with most being a mixture. Starting technical and progressing to management. • Professional Engineers vs. Non-licensed Staff
RELATIONSHIP BETWEEN ROADWAY DESIGN AND THE ENVIRONMENT All public transportation projects include some environmental component. If there is federal funding of any kind, very strict environmental processes must be followed. Even state and local funding sources are becoming more and more restrictive in this way. To a great extent, environmental issues will determine portions of the design of nearly every roadway project. Environmental processes for projects can last from a few months to a few years to several years or decades. They can cost millions of dollars. Some roadway design engineers specialize in conceptual and preliminary design to support environmental processes.
RELATIONSHIP BETWEEN ROADWAY DESIGN AND THE ENVIRONMENT • Environmental Impact Statement (EIS) • Environmental Assessment (EA) • Categorical Exclusion (CatEx) • Natural Environment Issues: • Wetlands • Unique water features • Threatened and Endangered species • Air quality • Water quality • Hazmat • Others
RELATIONSHIP BETWEEN ROADWAY DESIGN AND THE ENVIRONMENT • Environmental Impact Statement (EIS) • Environmental Assessment (EA) • Categorical Exclusion (CatEx) • Built (human) Environment Issues: • Noise • Right of Way • Environmental justice • Energy • Economics • Others
Roadway Project Development Process Let’s brainstorm the main steps in a typical transportation improvement project. Homework assignment #1 Research one of the following: Career opportunities for roadway design The Interstate system history and present day information A specific transportation project of significance in the US Write a technical memo to me, with no more than 2 single-spaced pages, describing your findings. Why did the topic interest you? Did your research present some of the things we have talked about tonight? Specifically list how your research relates to at least 3 of the topics we discussed tonight.
