Future

Responding to congestion/incidents in real-time

• Enhanced intersection detection and mid-block detection provide real-time feed to the ATMS to calculate congestion levels and trigger actions, to automatically change plans, or update DMS.

• ATMS integration with CCTV provides system operator visibility to the street, permitting them to use remote controls to manually flush intersection, or implement plans

Future

Providing real-time traveler information

• Arterial level congestion level information collected by mid-block detection and intersection detection, and be sent to public facing web-site, agency partners, or media outlets.

• CCTV images can be provided to public, partners, and media outlets.

• Bluetooth travel times and congestion information can be communicated to public via DMS

Future

Reducing travel delay and emissions

• Upgraded controller software allows collection of high resolution intersection data, that can be used to optimize coordination.

• Live split report data, can allow staff to monitor intersection performance in real-time, and see results of changes immediately.

Future

Improving capacity, travel time reliability, and optimizing

• Central system can integrate with Synchro optimization software, using actual detection information gathered by the ATMS and allowing import/export of timing plans

• Central system can provide, as needed, traditional time-based coordination, traffic-responsive, or even SynchroGreen adaptive operation

Future

Identifying and responding faster to equipment failures

• Diagnostic reports allow users to spot equipment trends, such as detection equipment failures.

• Real-Time alarms and events alerts personnel to hardware or timing plan issues via operator interface, or automatic texting/emailing.

• Performance reporting allows the agency to track plan performance overtime, and identify equipment or timing degradation trends
