Quick Facts: An Overview of New ClearGuide Volumes

15-minute interval 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.

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.

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

• Average Hourly Volume (AHV)
• Average Daily Traffic (ADT)
• Annual Average Daily Traffic (AADT)
• Vehicle-Miles Traveled (VMT)
• Vehicle-Hours Traveled (VHT)
• Vehicle-Hours of Delay (VHD)
• User Delay Cost (UDC)

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 1-5
• Most recent volume data in 15-minute intervals, updated quarterly
• Elimination of cost and work hours spent on volume data collection by other means
• Easy 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
