I-75 ICM - Transit Scenario Overview The ICM concept applied to transit has many potential applications which are dependent on the transit operations in a region. The study area contains a high level of transit options to include fixed route, demand response, and intercity rail (Amtrak). The potential ITS devices and deployments which come into play with transit related ICM deployments include, express bus, BRT, shoulder riding, enhanced park and rides and enhanced transit related traveler information.

Scenario One of the key parallel routes to I-75 in the region is M-1/Woodward Avenue. This heavily traveled, regionally significant corridor, is one of the major arterials in the region and also provides a significant transit route for SMART. This scenario begins with a transit passenger boarding the 450 Route bus at the Phoenix Center SMART Transit Center on Water Street in Pontiac. Before boarding this bus, which runs express from the Phoenix center to the Royal Oak SMART Transit Center, the passenger notes the arrival time of the 450 on the small dynamic message sign within the transit center which provides real-time next bus arrival information for all routes within the transit center. Before the p passenger left the house, she knew the bus was on time since she subscribes to the MY SMART traveler alert service which notifies riders of any schedule delays in real time. Text Messages are sent directly to the passenger’s cell phone. Once on board the passenger finds a seat and rides the approximately 15 mile express bus to its destination. Along the way, the bus remains on time thanks to signal priority along the corridor which extends the green time of the signals along the corridor. This system works in coordination with the SMART bus’ automated vehicle location system which provides continuous location and schedule adherence information. As the bus approaches the SMART parking garage at Northwood Shopping Center, Center the passenger notices the dynamic “spaces available” sign telling commuters how many spaces are left. The passenger remembers seeing such a sign on I-75 the other day near the SMART Park and Ride near the Oakland Mall. The “spaces available” sign on I75 is targeted toward commuters going southbound into the city in the morning and lets them know how many spaces are available should they want to park at this transit center and take SMART the rest of the way to their work. The passenger arrives at their destination at the Royal Oak transit center on Woodward just south of 11 Mile Road. At the transit center she meets a friend who jjust arrived from Indiana at the Amtrak station located just across the street from the transit center. They are picked up by another friend who has just arrived by car and plan to continue their trip on westbound I-696. While waiting for their friend in the car to arrive, they see a real-time traffic map monitor mounted in the transit center that provides traffic conditions on the interstate and major arterials in the area and traffic seems to be moving well. Their friend arrives soon and they begin the final leg of their trip. Before the merge onto I-696 westbound from Woodward Avenue, an arterial side mounted DMS gives them real-time travel times. This sign says 20 minutes to Novi, their final destination.

I-75 ICM – Incident Scenario Overview ICM deployments strive to provide a corridor-wide, corridor wide integrated approach to the management of incidents, incidents events, and emergencies that occur within the corridor, including planning, detection and verification, response and information sharing, such that the corridor returns back to “normal conditions” as quickly as possible. Associated objectives include improve pre-planning and provide a coordinated response for incidents, events, and emergencies that have corridor and regional implications (e.g., common command structure), and develop a comprehensive training program involving all corridor networks and public safety entities. The potential ITS devices and deployments which come into play with incident and traffic management related ICM deployments center around increasing the quality and consistency of information shared with transportation professionals and the traveling public. This increased quality of information continues to rely on traditional ITS field devices but with enhanced communication structures, which many times have less to do with technology and more to do with institutional cooperation.

Scenario A Gaylord Michigan family is starting on a trip today to Michigan’s latest and biggest theme park: Di Disneyland l d Detroit. D t it Before B f th leave, they l th check they h k the th MI Drive D i website b it and d see although lth h there th i some is construction north of Flint, there are no accidents and traffic seems to be moving smoothing into the Detroit metro region. As they approach the Flint region, an accident occurs much further southbound on I-75 in the center southbound lane just before the Big Beaver Road interchange near Troy in Oakland County. The Oakland County Sheriff’s 911 Dispatch Center, receives multiple emergency cellular phone calls reporting a serious crash on I-75. The accident reportedly involves a truck and two cars. The reports are conflicting as to the exact location of the crash. Oakland County Sheriff’s 911 Dispatcher Center Ce te d dispatches spatc es tthe e cclosest osest ca car to tthe e incident. c de t S Since ce tthe e d dispatch spatc ope operator ato knows o s tthat at MDOT O has as CCTV in the area, they use their workstation to access the cameras through a web browser. Taking control of the camera, the 911 operator pans and zooms the camera till the incident is in clear view. The operator confirms a truck is involved but three not two cars are involved. The accident has blocked two lanes of traffic. The 911 operator has also entered the incident into their CAD system. Once this is logged, an automated message is sent to the MDOT ATMS and an alarm goes off at the operator’s workstation at the MDOT MITS Center in Detroit. The MITSC operator Th t verifies ifi the th incident i id t as wellll through th h the th CCTV and d opens their th i incident i id t log. l Th The MITSC operator chooses from a library of DMS messages and posts a message on the DMS sign on I75 southbound just north of the South Blvd exit near Pontiac. The message not only alerts drivers to the incident but also suggest an alternative route; in this case it suggests drivers divert onto I-75 business and take M-1/Woodward Avenue south. The MITSC operator also executes a pre-existing timing plan that has been designed specifically for traffic being diverted from I-75 to M-1. The MITS Center operator also post messages on arterial DMS along M-1 telling motorists the best place to reach I-75 southbound is s by ta taking g 14 Mile e Road oad eastbou eastbound do off o of M-1. Concurrently, operators at the Oakland County Road Commission’s TOC see the incident as well and monitor the situation insuring the system is accurately dealing with the influx of traffic on the surrounding county roads, specifically on 14 Mile Road where many of the diverted cars are getting back onto I-75 southbound. This information is also posted on the MI Drive website. After about 10 minutes an Oakland County Sheriff’s car arrives at the incident scene. The officer calls in via his 800 MHz radio to the Oakland County 911 Center and reports that the incident involving a semi-trailer truck and three cars is, i fact, in f t blocking bl ki the th two t southbound thb d lanes. l Th officer The ffi reports t that th t the th truck t k rear ended d d a car and d both b th are not drivable. The two additional cars rear ended the truck and they also sustained significant vehicular damage. There were no serious injuries, vehicle fires or gasoline spills. The officer reports that he is going to direct traffic through the one remaining open lane. The Oakland County Sheriff’s operator enters this updated information into the CAD and this information is shared automatically with the ATMS. (over)

The Oakland County Sheriff’s officer reports status on scene to the Oakland County Sheriff’s 911 Center periodically. After three hours, the officer reports that the truck and cars have been removed and the roadway is now open for traffic. The MITSC operator deletes the DMS messages, deletes the message from the MI Drive web site. The family y sees the DMS message g and follows the alternate route. Theyy also see the arterial DMS messages along the way and follow them back to I-75. They arrive at Disneyland Detroit (which is the only Disney theme park/casino in the world and have a great time at the happiest place on earth.

I-75 ICM – Traveler Information Scenario Overview The ICM concept promotes the concept that travelers today must be provided with a complete view of the corridor and its operation through the delivery of timely, accurate and reliable multimodal information, which then allows travelers to make informed choices regarding departure time, mode and route of travel. Associated objectives include expanding the network coverage and types of information gathered on corridor conditions (e.g., arterials, weather, air quality), providing a complete ATIS database with traveler information presented in a consistent matter (including a single graphical display of the corridor and all networks), and expanding the coverage and availability of ATIS devices.

Scenario As mentioned above, the ICM concept revolves around enhancing the quality and consistency of traveler information regarding departure time, mode and route of travel and ultimately en-route information as well. To achieve this integration all the traveler information resources in the region, across all modes need t be to b made d available il bl for f dissemination di i ti through th h a variety i t off venues and d devices. d i Th elements The l t which hi h need to be integrated include highway, arterial, as well as transit and rail. One possible approach toward this integration is enhancing one of the current regional traveler information resources such as MI Drive into a multi-modal system which would allow travelers the ability to pre-plan trips and make mode selections based on the information found on this enhanced integrated site. This integration would require the current MDOT speed, incident and construction information to be presented side by side with transit trip planning and real real-time time bus arrival information. Currently transit information is provided but primarily for intercity travel and then only links are provided to those sites. The ultimate goal of an ICM approach would be to provide users with the ability to plan a transit trip within the same on-line environment as they could plan their highway trip. Furthermore, although good travel condition information exists on the major interstates which have been instrumented by MDOT, there are large gaps in the ICM study area (specifically, US-24, M-1 and M-53). Although arterial travel times are an emerging data source and currently not available, the complete ICM vision for this corridor would include the important route (as well as potentially others) to provide the complete t traveler l information i f ti th vision the i i i striving is ti i t achieve. to hi Fi ll en-route Finally, t traveler t l information i f ti could ld be b achieved eventually, through programs such as 511 or through the newer enhanced navigation systems being deployed currently in many new vehicles. Both of these provide excellent venues to provide en-route information. However, these venues as well as all the pre-trip venues discussed above fall short of their goal if data-quality is below required thresholds. Another critically important aspect to a successful ICM concept is the partnership of the media; regardless if itit’ss through traditional radio and television or new internet and mobile devices. Much of what the public receives as traveler information is filtered through these entities even if the information originates from a public entity. The ICM vision would have the media being an active and integral part of the creation of the region’s traveler information data sources. Cooperation and coordination with these elements of the puzzle are critical for success.

I-75 ICM – Special Event Scenario Overview The ICM approach builds on the long history of transportation network improvement initiatives by managing delays on a corridor basis, utilizing any spare capacity within the corridor, and coordinating interfaces between modes and networks, thereby providing an efficient multimodal transportation system. Objectives include reducing overall travel times, improving predictability, and increasing transit ridership.

Scenario It’s December 23rd, two days before Christmas and the holiday shopping season is reaching its peak at the Oakland Mall just off I-75 in Oakland County. The traffic on I-75 is very heavy and the ramps onto 14 Mile Road are backing up onto the Interstate. The mall, a major traffic generator in the study area, has good Interstate access off of 14 Mile Road as well as housing a major SMART Transit Center. This scenario will discuss how an ICM approach would help during this type of special (pre-planned) event. t The Th elements l t discussed di d here h could ld easily il be b applied li d to t other th events t such h as sporting ti events t or concerts. During the holiday season, shoppers travel to the Oakland Mall by a variety of modes including both car and transit. With an ICM approach travelers arriving at the mall in their cars would have a variety of deployments helping make their trip safer, shorter and more reliable. The coordination begins with the primary traffic management systems in the corridor. Specifically, MDOT freeway management system managed out of the MITS Center in Detroit and the advanced signal system managed at the Road Commission for Oakland County (RCOC). ITS devices utilized to monitor and control traffic include CCTV along I-75 as well as 14 Mile Road. MDOT also has DMS location on both north and southbound approaches to the mall. The RCOC also has an advance adaptive traffic signal system in the area which can monitor and react to traffic conditions in real-time. During this type of special event MITSC operators would post messages warning motorists of the queues backing up on the Interstate at the 14 Mile exit. They would also post alerts on MI Drive where t travelers l could ld check h k pre-trip t i on traffic t ffi conditions. diti Th media, The di and d active ti partner t i any ICM in approach, would also be involved warning travelers through traditional venues such as television and radio as well as new media being pushed to mobile devices. During such an event the MITS Center would also increase the presence of freeway service patrol ensuring stalled or other vehicles in distress are removed quickly from the Interstate, thereby minimizing the effect on traffic flow. Finally, if an incident did occur, the CCTV, DMS and other traveler information devices within the corridor, working in coordination, would ensure the incident is detected, verified, and cleared quickly. Travelers approaching the mall in cars from a city arterial would benefit from the RCOC RCOC’s s SCAT system which adapts timings to changes in traffic in real time. During time of heavy traffic such as these, timing is adjusted automatically, enhancing the safety and reliability of the travelers’ trips. For travelers approaching the mall via fixed route transit busses of the SMART transit authority; their trips are enhanced in a variety of ways. First, pre trip information is available through the My SMART service which notifies riders of any schedule delays in real time. Text Messages are sent directly to the passengers’ cell phone. Likewise SMART’s trip planner provides real-time updates to schedules. If th begin they b i their th i trip t i att a transit t it center t or major j bus b stop, t nextt arrival i l information i f ti is i posted t d on smallll DMS which tell them how long it will be before their buss arrives. If they utilize one of the transit authority’s park and ride facilities. They will know how many spaces are available as they approach; because parking management systems oversee these facilities and provide space availability information to small arterial DMS mounted on the roadside.

I-75 ICM – Special Event Scenario (cont.) The ICM concept p creates and environment where all of the elements share information and coordinate in real-time to adapt to the flux of traffic as it changes during the day. Only through accurate information, institutional cooperation and pre-agreed upon operations responsibilities will such a system provide the safe and reliable system needed in the future.
