Experimental Design

12.1 INTRODUCTION

Much of what we know of transportation phenomena comes from

observation. Transportation professionals observe data, build a model,

and test their hypotheses. Ultimately, they agree that the model works and

can be used for estimation and prediction (within some predened limits),

or they agree that the model is not valid. Of course, a more likely scenario

is that they agree that more information is required.

is chapter is focused on designing experiments where data can

be obtained to test a driving hypothesis. First, the designed experi-

ment approach is compared ...
