Items to be Covered What are Automated Signal Performance Measures (SPMs)? History of SPMs Planning benefits Operations benefits Design benefits How to get Automated SPMs Summary All graphics and data presented today are pulled from the ITE Automated SPM webinar series presentations and the TIG website 5

What are Automated Signal Performance Measures? 6

What are Automated SPMs? Advanced data displays Asset management tool Eases field maintenance Aids timing and coordination Assists planning 7

What is high-resolution data? 8 Research for developing new performance measures Enumeration definitions for controller events developed Data was characterized as “High- Resolution Data”

High-Resolution data collection Controllers capable of high-resolution data logging *Manual data collection can be done if communications not available 9 Events are logged Data files are retrieved* Data is translated InterpretationAnalysis Data is archived

History of SPMs

Used by INDOT, UDOT, MNDOT NCHRP accepted 2013 focus technology More high-resolution data capable controllers National Traffic Signal Report Card scoring 11

History of SPMs 12

Planning benefits

Planning Benefits Prioritize signal timing Executive reporting Justify investments 14

Planning Benefits

Operations Benefits

Data analysis options Phase termination charts Coordination diagrams Approach speed diagrams Turning movement counts 21

Operations benefits Identifying equipment issues Verifying / addressing complaints 22

Operations Benefits EXAMPLE: Identifying broken equipment 23 Phases maxing out in the middle of the night Metric: Purdue Phase Termination

Operations Benefits COMPLAINT: Cycle is too long 24 Metric: Split Monitor

Operations Benefits COMPLAINT: Not enough green time 25 Metric: Split Monitor

Design Benefits
