Length
Approximately 4 hours.
Prerequisites
Engineering economy or similar course and a good understanding
of ITS systems and functions as presented in the course.
Objectives
This course provides students with a comprehensive look at the
scope and process of evaluation and the steps for accomplishing
an evaluation. Also covered are some specific mathematical calculations
involved in evaluation and tools used to evaluate ITS projects.
The subjects of use impacts, ITS benefits, and evaluation boundaries
are also discussed at some length.
The revised course objectives are as follows:
- Define
evaluation and explain why it is done.
- Discuss the ITS measures of effectiveness.
- List and explain the JPO's Six-Step Evaluation Process.
- Describe the tools and techniques used in ITS evaluation.
- Calculate the vehicle operating costs for a transportation project.
- Calculate the capital, operating, and maintenance costs for
a transportation project.
- Measure the user impacts of different transportation alternatives.
- Define the evaluation boundaries for the alternatives under
consideration.
- Define the benefits of an ITS project and its components from
current practices.
- Employ the IDAS software package that allows the user to estimate
the benefits and costs of ITS projects and their components.
