The ramp from SB Huron (Hamilton) to EB 94 will be closed through at least August.The ramp from NB Huron to WB 94 will be closed through at least August.One lane northbound and one lane southbound will remain open on Huron/Hamilton.Beginning next week and through at least August, the NB Huron to WB I-94 ramp and the SB Huron (Hamilton) to EB I-94 ramp will remain closed. Next week only, there are nighttime lane closures on I-94 planned beginning Monday night/Tuesday morning, 6/20 through Friday night/Saturday morning, 6/25 from approximately 9PM to approximately 5AM.BC (FHWA Class 4 and above): shown in number of vehicles and percentage of AADT.Traffic shifts and closures on Hamilton, Huron, Michigan, West Cross, and Washtenaw are posted to MDOT's Mi Drive Site.PA (FHWA Class 1-3): shown in number of vehicles and percentage of AADT.D%: Percentage of peak-hour volume (24-hour peak) in the peak direction during that hour.The accuracy of either of them are dependent on when and how much raw data was collected.

For short count (non-perm) stations, this is the highest hour. DHV-30: For continuous count (permanent, or perm) stations, this is the 30th-highest hour for the year.Design hour volume (DHV), K & directional (D) factors, passenger vehicles (PA), and business/commercial vehicles (BC) are calculated from AADT.For short count sites, it is estimated by factoring a short count using seasonal and day-of-week adjustment factors. For continuous count sites, it is calculated by summing the Annual Average Days of the Week and dividing by seven. AADT is the estimated mean daily traffic volume.The recommendations are being considered as MDOT moves forwards with the development of a nonmotorized traffic monitoring program.The report discusses the importance of a nonmotorized monitoring program, provides background on other states' nonmotorized count programs, and makes recommendations for how MDOT should proceed in building a nonmotorized count program.Toole Design Group's report is titled the Michigan Department of Transportation Nonmotorized Data Collection and Monitoring Program Guide and Implementation Plan.To provide an outline for the creation of a nonmotorized count program, MDOT hired the consultant firm Toole Design Group to make recommendations for creating a nonmotorized count program from the ground up.MDOT is currently only capable of collecting short counts on these nonmotorized facilities but is considering options for collecting continuous count data.MDOT is also in the early stages of collecting traffic counts on nonmotorized facilities, such as bike lanes, sidewalks and shared-use paths.The data gathered from continuous counts are used to create factors (seasonal factors for example), which are utilized in a process of normalizing short count data. They are costlier to maintain compared to short counts and are set up in different regions throughout the state to get as much variety in the traffic data collected via continuous counts as possible but provide far more accurate and detailed data compared to short counts. Continuous counts are designed to collect traffic counts 24 hours a day, seven days a week, for all 365 days in a year.Short counts are the most common as they are easy to set up and cheap to maintain but only collect snippets (generally over a 48-hour period) of traffic moving through a designated location (where the station is set up).There are two primary types of traffic counts that are used by MDOT: short counts and continuous counts.MDOT collects traffic data, in the form of traffic counts, on all trunkline (federal-aid) roads and works with individual local agencies (cities/villages, counties, metropolitan planning organizations, and regional planning agencies) to collect traffic data for non-trunkline roads via the Non-Trunkline Federal Aid Road Program (NTFA).Average annual daily traffic maps ( AADT Maps) - Traffic segment-based source of AADT and CAADT for both Trunkline and Non-Trunkline roads.MS2 Help Guide - longer, more complete help guide.Basics of Navigating TDMS - short, simple help guide.Transportation Data Management System ( TDMS) - Provides up-to-date traffic monitoring data by traffic count station.Resources of Traffic Monitoring Data in Michigan
