Quick Facts: An Overview of New ClearGuide Volumes

3 min. Read • Posted 09/11/2024 by Jeff Venables

15-minute interval probe data-based traffic volume estimates, now available in ClearGuide.

ClearGuide® Volumes complements speed data to provide new traffic analytics so agencies can:

  • Make even more precisely honed planning and operations decisions
  • Produce new types of vital reports from probe-based volume data

ClearGuide Volumes leverages:

  • Iteris ClearData’s curated, regularly updated historical volume data
  • Iteris ClearGuide’s cloud-based volume and speed/travel time analytics

ClearGuide Volumes is derived from proven machine-learning models, and available within the single ClearGuide total traffic solution UI as either a:

  • valuable add-on to the ClearGuide Roadways speed and travel time solution
  • volume-only option that does not include speed and travel time data

Average Hourly Vehicle Volume, as shown in the ClearGuide Roadways map with the Volumes add-on. Average Hourly Vehicle Volume, as shown in the ClearGuide Roadways map with the Volumes add-on.

Vehicle Volume by Day, shown in ClearGuide Roadways as a report. Compare with Average Daily Traffic (ADT). Vehicle Volume by Day, shown in ClearGuide Roadways as a report. Compare with Average Daily Traffic (ADT).

Average Daily Traffic is the sum of all 15-minute traffic counts for X days, divided by X. Average Daily Traffic is the sum of all 15-minute traffic counts for X days, divided by X.

Transportation Planners, TSMO Managers, Traffic Engineers, City Managers, Contractors, and more will benefit in different ways from the following new volume-based metrics:

For Planning

  • Mandatory Regulatory Reporting
    • Environmental Impact Reports (EIRs)
    • Highway Performance Monitoring System (HPMS) requirements
    • State and local compliance for:
      • New housing development
      • Infrastructure expansion projects
  • Enhanced Planning
    • Congestion modeling by traffic volume vs. speed percentages
    • Emissions impact estimates
    • Economic impact estimates
    • Responsible VMT-based planning

For Operations

  • Enhanced Traffic Impact Analysis
    • More granular trend analysis
    • Intersection-level performance indicators
    • Traffic volume-based work zone review
    • Augmented before-and-after studies that may include:
      • Impact of signal retiming on congestion by volume
      • Impact of speeding countermeasures on congestion by volume
      • Environmental impact of projects
      • Economic impact of projects

For Planning & Operations

  • Sensorless Data Collection
    • For roadways without field detection
    • 24/7/365 total network monitoring
    • Freshly updated, affordably acquired probe data
  • Roadway Capacity Management
    • Overflow-based MOT/detour planning
    • Disruptive event prep based on past volumes
    • Overflow-based evacuation prep
    • Overflow-based post-incident analysis

Summary

ClearGuide Volumes provides:

  • Crucial, difficult to capture traffic volume insights for mandatory regulatory reporting and enhanced performance analysis
  • Comprehensive volume data coverage, for roadway Functional Classes 1-4
  • Most recent volume data in 15-minute intervals, updated monthly
  • Elimination of cost and work hours spent on volume data collection by other means
  • Convenient visibility of volume data alongside other data sets
  • Easily generated volume reports that are cumbersome to produce yet regularly required
  • A unified platform that improves operational and planning efficiency, improving overall traffic flow and safety
