Steve Remias, Assistant Professor Assessing Detroit Regional Traffic Conditions Using Intelligent Transportation System Data Civil Engineering • Intelligent Transportation System (ITS) data can measure and monitor the operational performance of the Detroit road network as conditions change, including new public transportation, construction zones, and winter operations • ITS data can provide speed mobility graphs which can be used as a method for analyzing cost-benefit calculations • The speed mobility graphs quantify travel time delays along I-75 by analyzing 566 traffic message channels (TMC) that produced 983,778,775 travel time data points over a 5 year period [1] Jenna Kirsch, Student Research Assistant NORTHBOUND SOUTHBOUND Jan-2012 Feb-2012 Mar-2012 Apr-2012 May-2012 June-2012 July-2012 Aug-2012 Sep-2012 Oct-2012 Nov-2012 Dec-2012 Jan-2013 Feb-2013 Mar-2013 Apr-2013 May-2013 June-2013 July-2013 Aug-2013 Sep-2013 Oct-2013 Nov-2013 Dec-2013 Jan-2014 Feb-2014 Mar-2014 Apr-2014 May-2014 June-2014 July-2014 Aug-2014 Sep-2014 Oct-2014 Nov-2014 Dec-2014 Jan-2015 Feb-2015 Mar-2015 Apr-2015 May-2015 June-2015 July-2015 Aug-2015 Sep-2015 Oct-2015 Nov-2015 Dec-2015 Jan-2016 Feb-2016 Mar-2016 Apr-2016 May-2016 June-2016 July-2016 Aug-2016 Sep-2016 Oct-2016 Nov-2016 Dec-2016 Jan-2012 Feb-2012 Mar-2012 Apr-2012 May-2012 June-2012 July-2012 Aug-2012 Sep-2012 Oct-2012 Nov-2012 Dec-2012 Jan-2013 Feb-2013 Mar-2013 Apr-2013 May-2013 June-2013 July-2013 Aug-2013 Sep-2013 Oct-2013 Nov-2013 Dec-2013 Jan-2014 Feb-2014 Mar-2014 Apr-2014 May-2014 June-2014 July-2014 Aug-2014 Sep-2014 Oct-2014 Nov-2014 Dec-2014 Jan-2015 Feb-2015 Mar-2015 Apr-2015 May-2015 June-2015 July-2015 Aug-2015 Sep-2015 Oct-2015 Nov-2015 Dec-2015 Jan-2016 Feb-2016 Mar-2016 Apr-2016 May-2016 June-2016 July-2016 Aug-2016 Sep-2016 Oct-2016 Nov-2016 Dec-2016 International Bridge Exit: 344 Mackinac Bridge Exit: 249 Exit: 162 Zilwaukee Bridge Exit: 117 Exit: 115 Exit: 77 Exit: 61 Exit: 53 Exit: 48 Exit: 20 Ohio State Line International Bridge Exit: 344 Mackinac Bridge Exit: 249 Exit: 162 Zilwaukee Bridge Exit: 117 Exit: 115 Exit: 77 Exit: 61 Exit: 53 Exit: 48 Exit: 20 Ohio State Line NB TMC: 108P04207 SB TMC: 108N04207 0 350 Scale set to 350 hours per month Jan-2012 International Bridge Exit: 344 Mackinac Bridge Exit: 249 Exit: 162 Zilwaukee Bridge Exit: 117 Exit: 115 Exit: 77 Exit: 61 Exit: 53 Exit: 48 Exit: 20 Ohio State Line Mile markers Example of low congestion (65+ MPH) Location of interchanges by exit/mile marker Example of high congestion (25-34 MPH) Scale showing speed ranges NB TMC: 108P04205 SB TMC: 108N04205 NB TMC: 108P04206 SB TMC: 108N04206 NB TMC: 108+04207 SB TMC: 108-04206 OPPORTUNITY AND SIGNIFICANCE METHODOLOGY Reconstruction of 6 miles with one lane open in each direction [2] Mackinac Bridge toll booths consistently cause traffic congestion [4] Snowiest winter on record in metro Detroit [3] Consistent traffic congestion near interchanges in Detroit [5] NB TMC: 108P04207 SB TMC: 108-04203 NB TMC: 108+04205 SB TMC: 108-04204 NB TMC: 108P04204 SB TMC: 108N04204 [1] Data provided by the Michigan Department of Transportation (MDOT) via HERE [2] Photo taken from The Houghton Lake Resorter [3] Photo taken from Detroit Free Press [4] Photo taken from Fox News [5] Photo taken from The Detroit News [6] Remias, S., T.
