[3] The project was initiated by the San Diego Association of Governments (SANDAG) in June 2005, in cooperation with the City of Escondido and NCTD.

The previous service was prone to bus bunching, heavy boardings near schools on the south end of the route, and traffic congestion in key locations during the morning and evening commute periods.

[5] However, Breeze Rapid Route 350 does not include dedicated right-of-way, off-board fare collection or platform-level boarding.

[7] The Breeze Rapid brand is no longer present on NCTD's web site or Rider's Guide.
