MicroTraffic's Global Beta Program in Surrogate Safety will advance the state of the practice and enable peer exchange in the field of road safety video analytics.


Participants will include consultants, state DOTs, cities, counties, and provinces. The Global Beta Program in Surrogate Safety will be the largest study of its kind ever undertaken.

Global Beta Program - Executive Highlights

  • Participants will supply video (see details below)

  • Participants will receive cutting edge, proactive diagnostics reports  for their own intersections

  • Participants will provide user feedback that leads to a synthesized research report on the Global Beta Program. This report will contain lessons learned and future directions. It will be shared with the TRB Subcommittee on Surrogate Measures of Safety.

  • Participants contribute beta user fees ranging from USD $5,000 to $50,000 depending on the number of intersections analyzed.

  • The Expression of Interest window for the third cohort of participants closes on May 15th, 2019.

Global Beta Program in Surrogate Safety - Details

Program Objectives

The program objective is to deploy concepts from the TRB surrogate safety subcommittee into the real world of traffic safety engineering, refine those concepts, and document lessons learned for peer exchange. Practitioners will get access to cutting edge methods, while the science of surrogate safety will benefit from being stress tested in multiple decision-making contexts.

Program Steps

Global Program Report

Receive a report documenting perspectives and lessons learned by practitioners across the global program, which will be shared with the TRB Surrogate Safety Subcommittee

Types of Data Produced

This can be customized with individual beta users, within our capabilities. We often produce the following data:

  • Safe systems post encroachment time

    • This metric considers the gap time in ​a near-miss, the speeds of the road users, the user types involved and the conflict configuration. Severity is a function of all of these. 

    • A severity-classified scatter plot is produced for every movement pair. 

    • The percentage of high severity events is compared to benchmarks using relative risks to identify anomalies. For example 2% of left turners in critical risk compared to 0.2% benchmark is a relative risk multiple of 10X (abnormally high).

  • Near-miss data for vehicles, pedestrians, and cyclists​

  • Speed profile distributions by vehicle movement at crosswalks

Above: Safe Systems PET Scatterplot for 24 hours for stop controlled NBL vs highway EBT. Abnormal proportion of critical risk events suggests a serious crash is imminent and that a proactive intervention can save lives.  

Above: Daily pedestrian conflicts, for each crosswalk and vehicle movement, color-coded by severity. Regarding left hook risk, data suggests NBL protected phase or LPI on  west crossing may improve safety. There also appears to be a major problem with jaywalking or red light violations.

Beta Program Participation Costs

The participation cost will range from USD $5,000 to $50,000 depending on the number of locations selected by the beta user. To obtain detailed pricing tiers and the number of intersections in each tier, please register your expression of interest at the top of this page. 

Video Requirements

  • Our aim is to help you leverage existing and available video assets

  • Resolution: HD, preferably with a wide angle lens

  • Frame rate: minimum 15 FPS and preferable 30 FPS

  • Mounting height: minimum 23 feet  (7 m)

  • Mounting location: within 40 m of target observation area

  • We have successfully used video from Miovision Scouts and Countcams, but due to the low resolution of these devices, the effective range is low and often two cameras are needed to effectively monitor an intersection. 

  • Our system has the capability to process footage from Miovision Smartview 360 cameras

Beta User Responsibilities

  • Identify analysis and diagnostic objectives for each intersection

  • Document broader learning objectives for the program with respect to surrogate safety techniques

  • Obtain video and provide it via a file request link or by sending memory drives in the mail

  • Review diagnostic results and seek to make relevant safety improvements

  • Answer a beta user questionnaire to support the global program report

  • Review the global program report

Existing Users and Deployments

MicroTraffic has been deployed by a community of alpha users including consultants and government agencies in 5 U.S. States, 5 Canadian provinces, and 5 countries outside North America. These tests have produced useful diagnostics leading to more than $20 million in approved road safety improvements. The tests also yielded useful feedback to advance the state of the art for the next round of users in the Global Beta program. 

About the Coordinator of the Global Pilot Program

Craig Milligan received his Ph.D. in Civil Engineering at the University of Manitoba as a Vanier Scholar with a focus road safety performance forecasting. As a consulting traffic safety engineer, he has completed over 200 road safety audits representing $6B of new construction audits, 175 in-service intersection audits, and 3500 km of in-service highway audits. He has updated 10 agency safety and design guidelines, and he has implemented highway safety manual predictive techniques at 4 agencies. He is chair of the Transportation Association of Canada Road Safety Standing Committee and a volunteer course instructor in road safety audits and road safety management for the International Road Federation.

Craig co-founded MicroTraffic to address pervasive data problems in road safety diagnostics, aiming to empower engineers to use AI, computer vision, and ITS assets in a proactive, safe systems approach to vision zero. He believes that we can save thousands of lives by transforming terabytes of video from hundreds of thousands of intersections into actionable risk management intelligence.​

MicroTraffic is a leading provider of microscopic traffic data for road safety engineers. Our technology is based on computer vision, video analytics, machine learning, predictive modelling, and the safe systems philosophy. We assist engineers to apply surrogate safety methods for proactive decision making. We produce conflict reports for individual traffic safety studies and also offer a proactive road safety network screening service.
