3.1 INTRODUCTION

As transportation professionals, we are oen asked specic questions on

the construction, operations, and maintenance of the transportation sys-

tem. For example:

Was the pavement constructed to the proper specications?•

Are cars going too fast on a highway?•

What is the average travel time from point A to point B?•

What is the capacity of a canal lock?•

In many cases, we can derive analytical solutions to these questions

based on rst principles. Oen, however, the answer has to be derived

from empirical measurement. In this situation, the engineer will need to

collect data in the eld
