CONTROL ROOM ACTIVITY

INFORMATION DISSEMINATIONMore…SEMTOC u lizes social media and the Mi Drive website and mobile appto disseminate traffic-related informa on to motorists. At the end ofFY16, there were more than 18,000 Twi er and 19,000 Facebookfollowers. More than 20,000 tweets and 1,300 Facebook posts wereshared.

What this means...It means that more drivers are aware of current roadway condi ons, andcan therefore make more informed travel decisions, resul ng inimproved mobility.

More…Operators handled more than 18,000events in FY16, which is 1 percent morethan in FY15 and yields an average annualgrowth rate (AAGR) of 4 percent over thelast four years. System maintenance eventsdecreased by 22 percent compared to FY15.

What this means...Operators are involved in more events, andthe ITS network and associated equipmentare becoming more reliable over me, asindicated in the decrease in systemmaintenance events.

Social Media

Mi DriveMore…The Mi Drive site(www.michigan.gov/drive)received nearly 3.4 million visitsduring FY16, which is a 26percent increase over FY15. Also,by the end of FY16, the Mi Driveapp had been downloadednearly 100,000 mes. February2016 received the most visits,nearly 350,000.

What this means...It means that more drivers relyon Mi Drive informa on as partof their trip planning efforts, andits popularity is increasing,especially through the use ofmobile devices.

SEMTOC has increased the frequencyand improved the accuracy ofweather informa on repor ng as itpertains to traffic. Similarly, SEMTOCac vely monitors and analyzesfreeway flooding events to iden fytrends. Through correla on with theUnited States Geological Survey(USGS) and the Na onal Oceanic andAtmospheric Administra on (NOAA)rainfall intensity and volume data,SEMTOC can forecast impacts onvulnerable areas and deployresources more efficiently.

Control Room Events by Type

More…The FCP program covers more than 325 miles in Metro Detroit.During FY16, FCP drivers patrolled more than 950,000 miles andmade nearly 44,000 assists. When not ac vely involved in an assist,FCP drivers patrol their routes as a proac ve means to find addi onalassists. In FY16, 29 percent of the me drivers were dispatched tothe assist; meanwhile, the other 71 percent of assists were found onpatrol.What this means...By ac vely patrolling specified routes, FCP is able to detect moremotorists in need in a quicker fashion and keep MDOT’s roadwaysfreer of interferences, which in turn can improve mobility throughoutthe region.

Average Response Time (in minutes)

More…Response me is the me from detec on to when the FCParrives on scene. Clear me is the me from FCP arrival towhen FCP vehicles have cleared the scene. Response mesmay vary depending on the volume of vehicles on theroadway, other assists that may be found while en route tothe original dispatched assist or the number of FCP driverson duty during the given shi . The average response meand clearance me across all shi s are 7 percent less and 6percent more, respec vely, compared to the averages overthe last three years.What this means...The lower response me means that MDOT is staffing andstaging FCP resources more effec vely based on roadwayneeds, and SEMTOC is u lizing those resources throughdispatch to mi gate impacts along the roadway moreefficiently; however, the higher clearance me may be anindicator that some assists were more me-intensive orinvolved more on-site resources than previous years.

INCIDENT MANAGEMENT

More…Clustering evaluates incident frequencies at nearby loca ons to iden fy trends. Aclustering hot spot is an area where incidents are more likely to occur throughout theregion, and is defined as a grouping of mul ple loca ons that present a high occurrence ofincidents. The occurrence of incidents at other loca ons is more randomly distributed.

What this means...By iden fying hot spots, SEMTOC can more effec vely stage resources used for reducingthe occurrence of incidents or the me needed to detect, respond to and clear an incidentthat has occurred.

Incident Clustering MapTop Incident Hot SpotsAs indicated on the map, thereare areas along the freewaynetwork that experience moreincident ac vity than others.Throughout Metro Region, thetop loca ons containing clustersof incidents are:

· I-75 @ 12 Mile Road

· I-75 @ I-696

· I-75 @ I-94

High-Impact IncidentsHigh-impact incidents are thosethat result in a freeway closure inone direc on, a freeway-to-freeway ramp closure or whenmore than half of the availabletravel lanes are blocked. Of the10,207 total incidents managedduring FY16, 1,546 were high-impact. On average over the lastfour years, high-impact incidentsaccount for approximately 16percent of all incidents.

Year-to-Year TrendThe last four years have shownan AAGR of 8 percent for totalincidents managed. SEMTOC hasbecome a more integralstakeholder in incidentmanagement by u lizing itsresources to improve detec on,management and clearance ofincidents. The graphic indicatesannual incident totals and year-to-year growth.

MOBILITY

CONNECTED VEHICLESMDOT is globally recognized as an industry leader in connected vehicle (CV) technology for nearly two decades. Recentdevelopments include partnering on applica ons for real- me work zone informa on for major reconstruc on projects, such asthe I-275 construc on and I-75 mega project that provide opportuni es for tes ng CV informa on and safety messages.

In addi on, MDOT partnered with the U.S. Army Tank Automo ve Research Development and Engineering Center (TARDEC) todeploy six roadside units (RSUs) along I-69 in St. Clair and Lapeer coun es. The partnership tested the func onality of dedicatedshort-range communica ons (DSRC), allowing military vehicles to “talk” to one another and the infrastructure. The tes ng in June2016 was the first me the U.S. Army tested vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) capabili es on a publichighway.

Addi onal CV infrastructure deployments are scheduled, and this will allow SEMTOC and its suppor ng systems to collect,process, analyze and apply the informa on gathered to make data-driven decisions for trafficopera ons. MDOT has partnered with the Michigan Economic Development Corp. (MEDC), academicins tu ons and other public en es in developing a marke ng campaign designed to foster futuredevelopments in CV and keep Michigan’s status as a leader in this space. More informa on onmobility and CV technology in Michigan is available at www.planetm.com.

More…A bo leneck is defined as a loca on where the actual reportedspeed is below 60 percent of the 85th percen le speed** formore than five minutes. Westbound I-696 at I-96/I-25/M-5 wasthe most prominent bo leneck loca on in FY16 and experienced306 occurrences of queues extending up to 6.5 miles long andlas ng just under two hours on average.

What this means...Loca ons ranked as bo lenecks are considered to be some ofthe most congested loca ons within the roadway network. Byacknowledging them as such, SEMTOC can more closely monitorand manage traffic opera ons in the surrounding areas, u lizeits resources, such as FCP, to manage factors that may worsencondi ons and iden fy opportuni es for bo leneck mi ga on.

Vehicle Miles Traveled(VMT)

User Delay Costs(UDC)

Vehicle Miles Traveled and User Delay CostsMore…VMT measures the total miles driven by all motorists on thefreeway network. UDC is a monetary measure of the impactsof conges on on motorists. The AAGR for VMT and UDC overthe last four years are 1 percent and 7 percent, respec vely.Similarly, the UDC per VMT has an AAGR of 6 percent over thelast four years.

What this means...The average increase in VMT indicates that more vehicles areon the roadway and/or longer distances are traveled per trip.The average increase in UDC means that occurrences ofconges on are longer or affec ng more motorists. The AAGRof UDC per VMT of 6 percent indicates that drivers areexperiencing slightly higher delay per mile traveled.

BLUE WATER BRIDGE TOC

More…Over the past three years, the non-commercial Blue Water Bridge users have decreasedby 21 percent; however, the commercial vehicle traffic has increased by seven percentresul ng in a net decrease of 13 percent for total traffic.

What this means...While the overall volume of traffic using the bridge has decreased, the commercial trafficincreases may have a greater impact on conges on and mobility at the bridge, due to thenecessary inspec ons required at customs, and as a result operators may be required tochange lane management messaging more frequently to accommodate the queues thatmay form.

US Bound Inspection Sign Changes by TOC

The Blue Water Bridge is aninterna onal border crossingbetween Port Huron, Michigan,United States and Sarnia, Ontario,Canada.

MDOT maintains a TOC at the BlueWater Bridge, known as the BlueWater Bridge TOC (BWB TOC).Control room operators at BWBTOC monitor and manage trafficalong MDOT-owned freewaysthroughout St. Clair County.Addi onally, operators helpmanage the traffic using the BlueWater Bridge through ac va on oflane management signs whichindicate to drivers which lanes areavailable for use upon entering UScustoms.

Blue Water Bridge

More…When queues develop in the westbound direc on of the bridge (entering the US) as a result ofpassing through US Customs, MDOT and Customs personnel work together to manage thelanes available for various inspec on ac vi es. In FY16, MDOT assisted by changing theadvanced-warning inspec on sign 3,337 mes so drivers could more easily navigate to theappropriate lane.

What this means...The increase in number of mes the message on the inspec on sign was changed indicatesthat MDOT has played a more integrated role with Customs personnel in managing the trafficon the bridge and mi ga ng conges on. The percent change values per day may be anindicator of shi s in traffic pa erns throughout the week as well. Customs personnel maintainthe safety of the US as a top priority; MDOT maintains the safety and efficiency of its roadwaynetwork as a top priority, so working collabora vely at the Blue Water Bridge interna onalcrossing improves overall safety of motorists and US ci zens.

What is travel time reliability?One of the most important ques ons a driver asks before making a trip is, “How early should I leave to arrive on me?” A certainlevel of traffic conges on is expected during par cular periods of the day, usually the morning and evening peak periods; however,unexpected conges on (e.g., as a result of an incident) can cause frustra on when planning a trip. Travel me reliability is ameasure of how consistent travel mes are along a segment of roadway over me. It analyzes average travel me as well asplanning me. Planning me represents a travel me reliability of 95 percent, i.e., the amount of me the driver should allow fortheir trip to be on me 19 mes out of 20. Metro Detroit drivers can use this data to make be er-informed decisions whenplanning their trips since travel mes are a good indicator of freeway performance and reliability.

What are the travel time chart parameters?The charts on the following pages present travel me data for common freeway segments used by commercial and passengerdrivers. Using historical data (October 2015 – September 2016), the average weekday travel me and planning me was calculatedfor each hour of the day. Note that southbound I-275 was closed between M-14 and I-696 for reconstruc on from April to June2016 and northbound I-275 was closed between M-14 and I-696 for reconstruc on from June to September 2016, the chartspresented for the I-275 corridor exclude data from these periods.

AVERAGE TRAVEL SPEEDWhat is average travel speed?Average travel speed is calculated as the distance traveled over the me of the travel. Various technologies are in place alongMetro Region freeways to collect actual travel speeds in real me and analyze historical data. Throughout the Metro Region,freeway speed limits range from 55 to 70 miles per hour, and drivers expect actual travel speeds to be at or near the posted speedlimits. During peak periods, however, when conges on levels increase, travel speeds typically decrease. By analyzing historicalspeed data, SEMTOC is able to provide drivers with more realis c average travel speed expecta ons during the peak periods of theday.

What are the peak average speed chart parameters?The charts on the following pages represent the average a.m. (midnight to noon) and p.m. (noon to midnight) peak hour travelspeeds along Metro Region freeways. The peak hour for each corridor was chosen as the hour with the lowest average speed. Thespeeds for that hour were averaged for Monday through Friday between October 2015 and September 2016 and plo ed along thecorridors at each interchange. The speed plo ed at a given interchange represents the average speed along the segment offreeway between the upstream interchange and plo ed interchange. Note that southbound I-275 was closed between M-14 and I-696 for reconstruc on from April to June 2016 and northbound I-275 was closed between M-14 and I-696 for reconstruc on fromJune to September 2016, the charts presented for the I-275 corridor exclude data from these periods.

6SPECIAL EVENT TRAFFIC MANAGEMENTSEMTOC rou nely coordinates with various stakeholder agencies before, during anda er special events. SEMTOC also hosts interested stakeholders at the mul -agencycoordina on command (MACC) center, which provides a space for consolidatedopera ons during the event.

WRONG-WAY DRIVER ALERTSIn 2016, SEMTOC began deploying wrong-way driver messages to alertmotorists when there may be a vehicle traveling against the flow of traffic.Seventy-eight wrong-way driver events were managed during FY16.

WEATHER EVENTSSEMTOC is able to monitor and proac vely provide alerts throughout the region tomanage weather events such as the flooding on Sept. 29 or snow that affect commuter’stravel.

CLOSING THE (COVERAGE) GAPThroughout FY16, MDOT installed 27 CCTV cameras along I-75 between Lapeer Road(Mile Marker 81) and Dixie Highway (Mile Marker 106) and integrated them intoSEMTOC’s intelligent transporta on system (ITS) network, thereby closing the gap incoverage along I-75 in Oakland County.

WORK ZONE COORDINATIONSEMTOC provided work zone informa on to motorists and media outlets, includingthat for major road work along I-275. Detour routes and real- me closures wereposted on DMS, Mi Drive and Twi er.

SEMTOC assisted with emergency road closures, such as on July 24, 2016 when a semitruck went through the Dearborn Street bridge on northbound I-75, landed on thesurface below, and ul mately closed I-75 and Dearborn Street . Upon receivingno fica on, SEMTOC quickly alerted media partners and posted messages to MiDrive, DMS and Twi er.

EMERGENCY ROAD CLOSURES

The Blue Water Bridge (BWB), is an interna onal border crossing between the U.S.and Canada. Control room operators at the BWB TOC manage the traffic volumes byusing the bridges lane management systems.

BLUE WATER BRIDGE

AUTOMATED MI DRIVE POSTINGSOn March 15, 2016, the advanced traffic management system (ATMS) was upgradedto automate the process for pos ng traffic incidents to Mi Drive, which means thatthe informa on is available to the public sooner.
