Roundabouts have become significant traffic control measures, and this book evaluates the operating conditions of them. It illustrates the calculation of the capacity, waiting phenomena, waiting times and queue lengths. It includes fully worked examples.

Roundabouts have become one of the most significant traffic control measures because they are generally statistically safer and more efficient than traditional at grade intersections. This book is dedicated to the evaluation of the operating conditions of roundabouts. In five parts, it thoroughly illustrates the calculation of the capacity, including reliability, and waiting phenomena parameters, such as the times spent in the system and queue lengths. Fully worked examples are included throughout the chapters, with detailed explanations.
