Measuring Mobility: Quality, Quantity, Utilization, and Accessibility

The previous two chapters discussed the fundamental traffic stream parameters and capacity, which provided the fundamental components for understanding traffic stream performance and for developing models to replicate the operations of traffic streams. For practitioners and policymakers, it is most important to be able to use valid traffic flow models to extract suitable performance measures. Such performance measures are used to evaluate traffic operational performance and select the best alternative for implementation. Therefore, they play a very important role in selecting the projects to be deployed. But what are these performance measures and how should we select the most suitable one(s) for a given situation?
