Signal retiming
Keep corridors moving reliably with continuous corridor performance insights across the network
Monitor daily corridor performance without hardware using network-wide real-time and historical traffic insights. Identify emerging congestion before complaints escalate, prioritize signal retiming opportunities, and validate travel time improvements.
Increase travel reliability across your corridors with daily traffic monitoring—without manual counts or hardware
Respond to planned and unplanned traffic disruptions and their network ripple effect with real-time and historical data directly from your computer.
Monitor speeds, travel times, and queues to quickly identify underperforming corridors and recurring congestion patterns.
Track live traffic conditions and receive alerts as congestion builds to respond faster to incidents, events, seasonal traffic shifts, and changing corridor conditions.
Compare before-and-after conditions to measure travel time reliability and queue reduction, and address public complaints and stakeholder questions.
Make fast and defensible decisions with insights and alerts, purpose-built for traffic operations

Three months of data on 40 intersections
Read case studyThe city of Temecula received a HSIP grant to coordinate traffic signals better for safer city streets and improved commute time. To perfect signal timing, planners needed comprehensive intersection data sliced by the time of day and day of the week to understand the causes and locations of current intersect slowdowns.
In a single day, engineers ingested StreetLight TMC analysis of 40 intersections on four major travel corridors segmented by day type and daypart. The effort would have taken three months using traditional data collection and would have been significantly more expensive. Analysis revealed precisely when and where true peak traffic occurred, enabling engineers to retime signals and optimize traffic flow.

Signal retiming is the process of adjusting traffic signal timing to improve traffic flow, reduce delays, and increase travel time reliability. Using real-time and historical traffic data, agencies can identify where retiming is needed, prioritize corridors, and measure improvements after implementation.
StreetLight’s Signal Retiming solutions combines historical intersection counts and real-time traffic data (via Streetlight’s Traffic Monitor platform) to help agencies identify congestion and changing traffic patterns early, enabling proactive signal retiming decisions. StreetLight’s Traffic Monitor platform provides live traffic insights and alerts to improve traffic flow, reduce delays, optimize corridor performance, and validate signal timing improvements without relying on manual field counts.
Daily traffic monitoring data helps traffic engineers track recurring congestion, peak-hour trends, and corridor performance over time. StreetLight’s Traffic Monitor enables agencies to prioritize corridors for retiming, validating timing plans, and making more data-driven signal optimization decisions.
Yes. We provide APIs that can complement your existing systems and ATSPMs by adding real-time and historical traffic analytics.
The Traffic Monitor platform includes instant, always-on access to real-time and historical data. This allows practitioners to compare real-time disruptions to typical conditions, including when volumes exceed or fall below normal thresholds. For practitioners working on Active Traffic Management, we offer a continuous feed updated in real-time. Real-time data is updated every 1-2 mins, and near-real-time is updated every 24-48 hrs.
In addition to the real-time data, StreetLight also provides intersection counts to help access the traffic on any intersection.
