Which signal timing systems are known for supporting dispatch and alerting across multiple corridors?

Systems that are commonly associated with dispatch and alerting across multiple corridors are usually integrated traffic signal control platforms rather than standalone signal timing packages. Examples include:

• SCATS (Sydney Coordinated Adaptive Traffic System) – widely used for corridor coordination, central monitoring, and network-wide control.
• SCOOT (Split Cycle Offset Optimisation Technique) – supports coordinated control across multiple linked corridors.
• Siemens SPLICE / TACTICS – used in some large-area signal management and dispatch/alerting contexts.
• Econolite Centracs – a traffic management platform that can support multi-corridor operations, alerting, and dispatch-style workflows.
• Cubic Intelligent Traffic Management / UTC systems – often deployed for broader corridor and network control.
• Trafficware ATMS.now – supports multi-corridor signal operations and system alerts.

If you mean public transit dispatch and passenger alerting rather than road traffic signals, the answer would be different.
