The operation of TxDOT traffic signals often crosses jurisdictional boundaries. For this reason, it is often necessary to connect or operate TxDOT traffic signals with signals and control devices maintained and operated by other jurisdictions.

Agreements.

If coordination across jurisdictional boundaries is accomplished by synchronizing time clocks (time-based coordination), then no agreement is necessary. If the coordination involves one jurisdiction operating (setting the timing) or maintaining (opening a cabinet for maintenance purposes), then a formal agreement between the entities is required. For information on agreements, see the
