The problem of bus bunching in a high frequency service has been largely studied in the literature.

This phenomenon is produced by three main factors

In order to tackle this phenomenon a wide range of control strategies have been proposed, however, none of them had been successfully implemented on a large transit network with high frequency services.

In this talk, we present a control scheme based on a rolling horizon optimization problem that has been successfully implemented for real-time control of two high frequency services in Santiago, Chile.

Finally, the main results and challenges on the implementation phase are discussed.
