Maryland State Traffic Trends Introduction

Subscribe to E-mail Alerts Subscribe to Email Alerts

Maryland Highway Traffic Trends is a summary of the traffic volume data collected by the Data Services Engineering Division (DSED) of the Office of Planning and Preliminary Engineering (OPPE). These are permanent, continuous counting Automatic Traffic Recording (ATR) stations throughout Maryland and seven continuously operating toll facilities. These reports contain tabulated data from these stations.

The purposes of this report are:

  1. To present the Annual Average Daily Traffic (AADT) and the hourly, daily, monthly and seasonal fluctuations in traffic volumes at the individual stations; and
  2. Provide factors from individual stations and ATR groups having similar characteristics that can be used to expand short term (typically 6, 12, 13, 24 or 48 hour) counts to AADT's.

For Traffic Trends, the stations were grouped based on functional classification and an additional summer seasonal group to reflect recreational traffic patterns during the summer months. The categories are rural interstate, rural other (including other rural arterials, and rural collectors), urban interstate, urban others (including urban other freeways and expressways and other urban arterial systems) and summer seasonal (stations that display high traffic patterns during the summer season).

The ATR station groups are as follows:

  1. Group 1 - Rural Interstate
  2. Group 2 - Rural Other
  3. Group 3 - Urban Interstate
  4. Group 4 - Urban Other
  5. Group 5 - Summer Seasonal

Note: 1

  • P0072 - IS 795 NB South of Mt. Wilson Rd (collecting Northbound Data)
  • P0073 - IS 795 SB South of Mt. Wilson Rd (collecting Southbound Data)
  • The merging of traffic stations P0072 and P0073 started in 2006 so the data for both directions can be reported like all other ATRS.

Note: 2

  • P0025 - MD 295 NB South of MD 100 (collecting Northbound Data)
  • P0081 - MD 295 SB South of MD 100 (collecting Southbound Data)
  • The merging of traffic stations P0025 and P0081 started in 2011 so the data for both directions can be reported like all other ATRs. 

Note: 3

  • P0044 - IS 68 EB East of MD 546 (collecting Eastbound Data)
  • P0082 - IS 68 WB East of MD 546 (collecting Westbound Data)
  • The merging of traffic stations P0044 and P0082 started in 2012 so the data for both directions can be reported like all other ATRs.
