Existing practices in the timing design of the signal change interval vary considerably. Attempts to provide a logical basis for the timing design are often focused on the understanding of how individual drivers react when they are confronted by a change interval. Driver behavior can be affected by numerous factors and is difficult to measure. In contrast, direct measurement of drivers' aggregated needs for the change interval can be performed easily. It can also provide information useful to the development of timing methods and to the assessment of existing change intervals. For these reasons, field observations of drivers' aggregated needs for the change interval were made at 10 intersections. The resulting data are used to evaluate various timing methods. The observed needs for the change interval indicate that timing models based on the specification of constant reaction time and deceleration rate may not adequately explain the aggregated needs of drivers.
