Maintenance and infrastructure insights

This is the final installment in our blog series on Traffic Insights. This post covers Maintenance and Infrastructure Operations. If you’d like to read other posts, check out links to the rest of the series below. 

In part 1, part 2 and part 3 this blog series, we covered Miovision’s vision for data-driven traffic operations. The first two categories of Traffic Insights are Signal Performance Metrics and Arterial Performance Metrics. They provide micro and macro-level insights for traffic planners.

This blog post covers how insights can help improve Maintenance and Infrastructure operations.

Part four: maintenance & infrastructure insights

Citizens expect traffic lights to work. City traffic teams are responsible for traffic signal maintenance and field operations, but without a system that informs the traffic department of problems in the network it can be difficult to meet the public’s expectation.

Even simple questions, like the ones below, can be hard for traffic pros to answer:

  • Where are the trouble spots for equipment failures in my network?
  • Which detectors appear to be performing unreliably?
  • How can I remotely determine if my maintenance contractors have resolved the signal issue to my satisfaction?
  • How often are signal issues occurring?

To help cities answer these questions proactively, Miovision has a set of reports and dashboards in TrafficLink. They are called Maintenance and Infrastructure Insights.

Three key reports

Maintenance insights forecast and justify maintenance and operating budgets across cities. They also have an eye toward elevated system performance. Here’s a look at the key reports:

  • Exception Reports: Roll-up views to occurrences of power loss, signal flash, detector failure, pre-emption failure, connection failure and UPS activity.
  • Maintenance Ticket Management: Reporting and tracking of average open ticket time from incident alert to resolution.
  • Intersection Maintenance Profile: Intersection history including uptime, summary of persistent maintenance issues and performance rankings of maintenance teams.

How are these reports generated?

To generate these reports, TrafficLink hardware monitors the intersection for maintenance issues or infrastructure failure. Data sources include the traffic controller, detection systems, and power supplies. This information generates maintenance alerts to the appropriate technicians or contractors as part of TrafficLink’s core signal management module. All event data associated with infrastructure or service issues are logged in TrafficLink’s cloud database. When the problem is fixed, a resolution event is logged in TrafficLink’s cloud database.

The database of infrastructure events is analyzed to determine maintenance trends and performance metrics.

What do maintenance and infrastructure dashboards and reports look like?

Maintenance Dashboard: Allows investigation of key trends in maintenance resolution time, uptime, and call volume. This information can be segregated between multiple zones in a city, allowing comparison between multiple groups of technicians.

Corridor Maintenance Priority: Offers corridor-level trend reporting on alert frequency, downtime, travel time and daily volumes.

Summary of Alerts: An annualized view highlighting monthly statistics for a given intersection, broken out by maintenance category, and time-to-resolution.

Pre-emption Summary: A history of pre-emption events, including those that remained active beyond the alert threshold.
