14.1 INTRODUCTION

In this chapter, we will present the basic concepts and principles of

Bayesian approaches as well as simple examples to illustrate the concepts.

In previous chapters we discussed exploratory plotting, estimation, and

hypothesis testing based upon eld studies or designed experiments.

Oen transportation researchers have more information about mobility,

signaling, safety, and materials than just the data at hand. By using a prior

distribution, that information can be used in a mathematically rigorous

fashion. is is particularly important when sample si ...
