Workshop - 2010

Short Count Processing


Traffic count headers
Traffic Count Headers

Station Headers in HDMS/RIS - 36,400

Ramps (in Off-Network Header)- 4,600

Grand Total - 41,000


Speed count layouts
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


Count processing changes
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.


Header file changes for 2011
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.

Impact on tce processing in 2011
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


Short count processing
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?


Ramp counting
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

Ramp stations counts
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.
