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.Intersection must meet at least one of the eleven signal warrants in FHWA's "Manual on Uniform TrafficĬontrol Devices.Resources of Traffic Monitoring Data in Michigan The intersection and a determination is made from these counts as to whether a signal is warranted. The Traffic Division then asks for 12-hour turning movements at Towns often call theĭepartment to request signal projects. The Design section is also responsible for checking signal warrants for intersections. Most projects are on the Interstate with some specialty sign The section is responsible for designing newĪnd replacement signs for roadway projects. Roadway signing is another function of the Design Section. The group uses FHWA design criteria to develop Lighting is an item associated with safety and delineating side roads and decision points. Responsible for providing other Bureaus within MaineDOT plans and specifications dealing with temporary traffic signals.Īnother function of the Design Section is the design of lighting plans. This would include the timing, phasing and layout of lane assignments. The Traffic Engineering Design section is responsible for the design and/or review of design for proposed traffic signals. This section is responsible for signal, lighting, signing plans and site reviews. This includes 1072 lights, 600 control points,ġ55 lighting towers, 518 fixtures, 104 beacons, 33 signals and 53 dynamic signs statewide. They are responsible for all of MaineDOT's signals, beacons, highway and bridge lighting,Įlectrical signs, and installing many of the new projects.
