What form should be utilized for deploying a Gap Filler?

The 10-43 Notification form is specifically designed for deploying a Gap Filler within the Chicago Transit Authority framework. This form plays a critical role in informing relevant parties about changes or enhancements in service operations that aim to address service gaps. By utilizing this form, the necessary details regarding the Gap Filler's implementation can be communicated effectively, ensuring that all stakeholders are aware of the adjustments and can respond accordingly.

In contrast, other forms serve different purposes. The Customer Statement is primarily used to document feedback or issues faced by passengers, focusing on their experiences rather than operational changes. The Daily Activity Report captures daily operations and occurrences but does not specifically address the deployment of service improvements like a Gap Filler. The Free Rider Report is used to record instances of individuals utilizing transit services without proper fare payment and is unrelated to service enhancement measures. Therefore, choosing the 10-43 Notification is the most appropriate course of action for deploying a Gap Filler.
