Transportation courses at UW

CEE 441 Highway and Traffic Engineering (4 credits)
This is the senior capstone course for transportation-construction.

CEE 404 Infrastructure Construction (4 credits). Covers basic concepts
of large infrastructure construction projects including planning, scheduling,
life-cycle cost analysis (LCCA), construction cost, logistics and productivity.
Involves a 7-week group project that plans a major repaving of an I-5
section in the urban Seattle area.

CEE 421 Pavement Design (3 credits)
Current and developing procedures for the structural thickness design of
pavements. Bituminous and concrete pavements for highways, airports, and
special heavy loading. Elastic layered systems, slab theory. Performance
evaluation for maintenance and overlay design.

CEE 410 Traffic Engineering Fundamentals and Surveys (3 credits)
General review of the fundamentals of traffic engineering, including their
relationship to transportation operations management and planning, with
special emphasis on traffic engineering field surveys and data analysis.
Transportation courses at UW

CEE 416 Urban Transportation Planning and Design (3 credits)
Brief review of major issues in urban transportation planning. Planning process discussed and
transportation models introduced. Uses a systems framework, including goals and objectives,
evaluation, implementation, and monitoring. A design term project, individual or small groups,
utilizes material presented on a contemporary problem.

CEE 498B Transportation Logistics (3 credits)
Students who complete this course will gain an understanding of the logistics system, and the
interaction between supply-chain management and freight transportation; how goods are
conveyed from production to consumption. Students will also gain a familiarity and facility with
common methods used to analyze logistics problems, and the tools needed to understand current
and future transportation choices in the transport of goods.

CEE 412 Transportation Data Management (3 credits)
Introduction to modern concepts, theories, and tools for transportation data management and
analysis. Applications of software tools for transportation data storage, information retrieval,
knowledge discovery, data exchange, on-line information sharing, statistical analysis, system
optimization and decision support.

CEE 579 Advanced Traffic Detection Systems (3 credits)
Introduction to advanced tracking and detection technologies in transportation engineering
including Global Positioning Systems (GPS), inductance loop detection systems, remote traffic
microwave radar, computer-vision based technologies, and other emerging detection technologies
with cutting-edge research in these areas.
Contemporary Issues in
Transportation
 The
impact of rising fuel prices
 Changing fuel sources
 Reducing the environmental costs of
transportation
 Resilience
 Security
 News
stories

Civil Engineers not only design and
build infrastructure, but plan and
manage.

Increasingly we will manage the
infrastructure through the use of
sensing technology and “dynamic”
infrastructure.

These strategies allow us to
manage the infrastructure and
demand for that infrastructure
“better”.

“Better” is cleaner, with less wasted
fuel and time, cheaper?

Although the transportation
system was designed by and
is operated by humans, we do
not understand it’s dynamics
well.

Drayage Trucks
What is the Clean Trucks Program?
 A proposal
by the Ports of Los Angeles
and Long Beach that would govern their
relationships with Licensed Motor Carriers
(LMCs)
 LMCs will need to obtain a concession
from the ports to do business there
 LMCs must employ their drivers, currently
most drayage drivers are owner/operators
What is the Clean Trucks Program?
 Trucks
will be charged a Transportation
Impact Fee for every entry into the port
($34) if the truck does not meet 2007
Environmental Protection Agency
regulations
 Trucks will be required to have GPS units
 Trucks will be required to have RFID tags
 By 2012 all trucks will be required to meet
2007 EPA regulations
Official Goal of the CTP

With the program in place, the ports should be
able to move forward with their infrastructure
plans to expand to a capacity of 42.5 million
TEUs while meeting the Clean Air Action Plan’s
goals
 Currently the ports moved about 16 million TEUs
in 2006
 The Clean Air Action Plan will cut particulate
matter (PM) pollution from all port-related
sources by at least 47 percent within the next
five years
Other Objectives
 Transfer
the burden of regulation from the
ports to the LMCs (security, safety,
environment)
 Increase transportation system efficiency

Provide a mechanism for financing a
technology investment at the port
 Improve
working conditions for drayage
drivers (estimate improvement from
$12/hour to $20/hour)
What is the threat?
 Southern


California will
Experience tighter environmental regulation
Lose it’s position as the main US Port of Entry
for goods from Asia
Lose the associated jobs and economic
activity
• “By roughly 2025, that will result in the ability of the
ports to support 300,000 to 600,000 new jobs that
would be lost if that infrastructure cannot be built.”

Current Operations
Anticipated Changes
 Change
size of drayage fleet
 Employ drivers
 Reduce gate delay
 Smooth truck arrival pattern
 Reduce empty trips

Summary

May not reduce overall delay.

Implementation of the program may result in mild improvements
through;

reduced gate delays,

fleet efficiencies,

increased driver tenure.

The possibility of disruption or inadequate truck or driver supply or
the cost of the program to the industry is certainly increased.

Consistent with other transportation developments in the use of
technology to manage the system both on the demand and supply
side.

System benefit requires transfer of cost.
