TDOT Traffic Count Program Review Preston Elliott, KCI & KB Aboagye, TDOT

Review of Current Count Program Project Scope Internal and External Outreach Review of Surrounding and Peer State Practices Needs and Recommendations

Review of Current Count Program Procedures and manuals Collection schedule (required and typical) Collection scope (geography, functional class, etc. ) Project Scope Collection methods (ATR, EDL, CC, etc. ) Types of data (volume, vehicle classification, travel time, occupancy, multimodal, etc. ) Users (internal and external) Responsibility (staff, consultant, etc. ) Current quality assurance methods Processing, final format, and storage

Project Scope Internal and External Outreach Interview TDOT’s internal partners (Long. Range Planning, Traffic Operations, STID, etc. ) Interview external partners (MPOs and RPOs) Online survey for other partners (municipalities, universities, professional organizations, etc. )

Review of Surrounding and Peer State Practices Project Scope Currently looking at: Ohio Oregon Minnesota Florida

Needs and Recommendations Project Scope Additional data needs, requests, and wants Real-time data, emerging technologies, etc. Partnering with MPO data collection efforts and other municipalities Statewide guidance for traffic collection

Findings To-Date Internal Engagement In general, TDOT: Is amenable to data sharing with partners Needs standardized methodologies throughout the program: How to collect traffic data for sharing purposes? How to choose/prioritize new count locations? How to collect WIM data statewide? How to improve vehicle classification counts? Has challenges associated with meeting HPMS sampling requirements

Findings To-Date External Engagement In general, MPO partners: Have a strong understanding of the availability and usefulness of TDOT data Primarily use TDOT’s AADT and crash data Are willing to share locally collected data Need more data on Federal and State routes Are very interested in turning movement counts Desire more communication regarding count station removal/addition and count timing

External Outreach Plan TNMUG Group Discussion Additional Outreach with MPOs, RPOs, and Municipalities Online Survey for Key Industry Partners (ACEC, TSITE, TAPA, universities, etc. ) and for Cities and Counties

Beyond current data collected, what is your priority for the following: Vehicle Classification Travel Time Discussion Items for Today Turning Movement Counts Occupancy Weigh-in-Motion Relative to TDOT’s traffic data, what are your thoughts/opinions on coverage, frequency/duration, quality, etc. ? Do you know of any count programs conducted by local municipalities within your planning areas? Other thoughts/comments on this topic?
