Enhancements in Short Count Processing for Traffic Data in HDMS/RIS

This workshop discusses the integration and processing improvements for traffic count data in HDMS and RIS, focusing on 41,000 stations with respect to speed count layouts and bin configurations. Key changes include a shift to a 14-bin classification system, enhanced data extraction from the RIS database, addition of new fields like DOTID and Ramp Code, and improvements in scheduling and monitoring software. Current ramp headers will be organized in a dedicated RIS database, streamlining data management and processing efficiency.

  1. Workshop - 2010 Short Count Processing

  2. Traffic Count Headers Station Headers in HDMS/RIS - 36,400 Ramps (in Off-Network Header)- 4,600 Grand Total - 41,000

  3. Speed Count Layouts • Universal bin layout scheme: • Expanding to 15-bins that are summarized to appropriate bin range. Bin Low (<50mph) High (50+ mph) Range Range 1 1 0 -20 1 2 2 20-25 1 3 3 25-30 1 4 4 30-35 2 5 5 35-40 3 6 6 40-45 4 7 7 45-50 5 8 8 50-55 6 9 9 55-60 7 10 10 60-65 8 11 11 65-70 9 12 12 70-75 10 13 13 75-80 11 14 13 80-85 12 15 13 85-999 13

  4. Count Processing Changes • After we shut down HDMS (?when?)…. • Change Class Bin Configuration to 14 bins – BIN 14 - unclassified vehicles • Tradas will extract Volume data from Class / Speed count files.

  5. Header File – Changes for 2011 • Header File will be an extract from RIS DB • Additional Fields: • DOTID • Ramp Code • One Way Code • Removed – Control Code (of COC) Expands Header file from 133 to 151 chars.

  6. Master Header File - Future Format -

  7. Impact on TCE Processing in 2011 • Process Volume files only when there is no Class or Speed Data • Extract Header data out of RIS – new format • GPS Coordinates – on TCE header screen • Lat/Long or UTM accepted

  8. Short Count Processing Improvements to be made……. • Combine channels of other counts to form another station. • Count Scheduling/Monitoring Software • Improve how “notes” are passed down the processing stream. • Any Other Ideas to Streamline Processing?

  9. Ramp Counting • Station assignments: • 3000-3799 Normal, scheduled Ramp • 3800-3899 Access/Directional approaches • Not normally scheduled • 3900-3999 Count station derived by sum of 2 or more normally scheduled stations • Not normally scheduled • 6000-6999 Ramp bridge station • Some are scheduled, some are derived from others

  10. Ramp Station Maps • \Highway Data Services Bureau\Traffic\Ramp Data\MAPS_AP\Reg XX • I-86_NY17 Exit 67.pdf • NY 5 8 12 & I-790 @ I-90.pdf • NY 5 12 @ NY8 Sauquoit Valley Art.pdf • I-88 Exit 20.pdf • NY 5 8 12 @ French Rd.pdf • I-88 Exit 17.pdf

  11. Ramp Stations / Counts • All Ramp headers currently reside in Off- Network Header file. • Ramp Headers will be maintained in RIS DB. • Ramp Counts will be housed in Tradas DB.
