Subject: Performance measure questions and Need your response by May 6th.
Dear Friends: ADOT is developing performance measures on Real-Time System Management Information
Program. Our focus area are: 1) Construction, 2) Incidents, 3) Weather, 4) Travel Time, 5) State-wide ITS
Architecture, and 6) Routes of Significance.
ADOT is now working on first four area and is measuring the performance of the system for accuracy, timeliness, and availability. Briefly, the performance measures includes how much of the event's information is being shared with travelers, how accurate they are and what percent of time each system is actively running.
Highway Condition Reporting System (HCRS) software is being used by ADOT for inputting any planned or unplanned events, incidents and weather related information either manually or automatically. This information disseminates to the travelling public through Dynamic Message Signs (DMS), AZ511 website and 511 telephone system. Furthermore, ADOT displays travel time and weather related information for the travelers on the DMS boards. ADOT and Department of Public Safety (DPS) actively work together
(Statewide) on Traffic Incident Management (TIM).
I would greatly appreciate if you respond to the following questions:
1) What are the focusing topics? 2) What are the performance measures? 3) How they are going to be calculated and/or estimated? 4) What are the data sources? 5) Whether that would be qualitative or quantitative?
Thank you very much. looking forward to hearing from you.

Reza,
Once again I appreciate the help you provided to me earlier. My responses are below.
Thanks and Regards,
Charles Remkes
1) What are the focusing topics? Construction - Impacts to traffic and congestion (within the zone only, not measuring adjacent arterials or parallel corridors); safety Incidents - Detection and
Clearance Time to Arrival (for our HELP Trucks) and time to Clearance (for our HELP Trucks - back in service) - HELP is our term for Motorist assistance Patrols; Timeliness of incident reporting Weather - Safety, Maintenance Operations, Traveler Information, Early detection of events and/or conditions that are indicators of events (dust storms) Travel Time - Currently focused on our freeways in the ABQ area using roadside sensors - will be expanding to include
3rd party probe data for municipal arterials ITS Architecture - we have five regional architectures,
Albuquerque, Santa Fe, Las Cruces, Farmington and a Statewide. Each architecture is being used

in conjunction with a Systems Engineering certification process (ITS Checklist) we have in place for identifying within each project opportunities for deploying technology (if the project is within an area where a need has been documented by the Architecture). This is done typically at 30% design, which if the estimate is at or above the budget, does not leave any room to include ITS. It's only for those projects that the estimate is below the budget by enough margin that ITS can be designed into the deliverable. To remedy this, we will soon require the Architecture(s) to be reviewed as part of the Location Study Procedures, to capture that potential as soon as it possibly can. Routes of Significance - most prominent for New Mexico are those municipal arterials in the
Albuquerque area. Through our ITS subcommittee, we've identified ITS corridors, which do include all of the principal arterials within the metro area. This pretty much covers the definition in 23 CFR 511 for Routes of Significance (routes available for use in diversions or alternate routes to freeway incidents or congestion, routes having congestion, routes where data is being collected,
....). Specific to the topic of focus are the compliance elements with 23 CFR 511, namely reporting of travel times, reporting of incidents and reporting of lane /road closures. We're working with municipal folks through our ITS Subcommittee to bring this into a manageable platform before the
2016 deadline. 2) What are the performance measures? Construction - Travel Time Delays through a Construction Zone Incidents - Time to Arrival (for our HELP Trucks) and time to
Clearance (for our HELP Trucks - back in service) - HELP is our term for Motorist assistance
Patrols; Timeliness and Accuracy of incident reporting to the public Weather - Accuracy and
Timeliness of event and/or road conditions reporting, Travel Time - Accuracy and refresh - targeting 95% accuracy at 90% frequency, 3 minute cycles ITS Architecture - Annual project updates, updates associated with either a change in boundaries or change in stakeholders, complete revisit as a maintenance procedure every 5 years Routes of Significance - lane / road closure / incident reporting within 10 minutes of verification, travel times on ROSs updated within 3 minutes 3) How they are going to be calculated and/or estimated? Construction - Responsibility of the construction contractor to provide smart work-zones and bring it into an environment where it can be displayed and shared using our existing information systems (NMRoads) Incidents -
Through TMC Dispatch Logs - entries are captured and time stamped Weather - Road conditions determined by qualitative assessment; Road closures made by State Police; Indicative conditions acting as a precursor to events are monitored by sensors. Notifications via an automatic push
(subscribership) or inter-agency teletypes (e-mails); vetting or verification established when information is received from the authorizing source (i.e., time-stamped notification of closures by police agencies). Entries of events into NMDOT reporting system is time-stamped. Elapsed time determined between this difference. ITS Architecture - need for updates established by associated
ITS Subcommittees for that respective region. Monitoring it's use in the planning process established through the Systems Engineering Checklist and determining the number of projects where opportunities for ITS deployment were lost. Routes of Significance - from third party probe data - there is a sparse population of blue tooth devices on some arterials, but not enough to provide full coverage and is questionable as a cost-effective alternative to obtaining full coverage
4) What are the data sources? Construction - Typically portable devices (trailer-mounted sensors, cameras, DMSs) that can be communicated with remotely using wireless modems. System controllers to be provided with an API that can be brought into the Departments reporting system.
Incidents - TMC Dispatch Operators, HELP Truck Drivers, Police Dispatch all communicating via radio operations; in the process of expanding the capability of the application we use for data management from feeds of our sensors along the freeways that would provide a notification to operators when user-defined thresholds are crossed (i.e., speed and volume differentials) and tie that notification to a map-based GUI along with other functional services (surveillance, traveler information) that can be used for quick verification and incident reporting. Weather - RWIS systems tied into a web application for user access and notification. CCTVs also provide an image of roadway and driving conditions at various locations throughout the state. Travel Time - On the freeways - roadside, side-fire radar units that measure Volume, Speeds, Occupancy and
~Classification. Directly tied, via DOT-owned fiber to data management application that is used to define and aggregate segments, and through measuring mean speeds, determines the travel times.
ITS Architecture - Stakeholder reporting during monthly ITS Subcommittee Meetings. Project updates during monthly PMTM meetings. Soon to be required within the Location Study
Procedures. Routes of Significance - subscription service from private providers. 5) Whether that

would be qualitative or quantitative? Construction - Quantitative Incidents - Mix, Includes a qualitative element in that the time to report involves some human input that includes a level of discretion and possible a variance to precision. Quantitative in that duration between detection and reporting and clearance is associated with a measurable time stamp. Weather - Mix, Qualitative in that road conditions determination from weather events (i.e., severe, difficult driving conditions) are based on qualified personnel's interpretation and when they get a chance to observe the roadway (weather by driving it or viewing the CCTVs). Quantitative in that reporting these conditions (once determined) have associated measurable time-stamps, and weather conditions impacting driving can be directly measured by the sensors at the RWISs. Travel Times -
Quantitative ITS Architecture - Mix, Qualitative in that its effectiveness relies on it being incorporated into process and procedures whose use is hard to measure, and whether a project having ITS elements gets approved for production is via approval by the MTB. Quantitative in the number of missed opportunities where ITS should have been considered for inclusion, but wasn't can be measured. Routes of Significance - As it relates to travel time reporting, quantitative. As it relates to incident / lane / road closure reporting mixed (see response to Question 5 for Incidents above)
