I-270 Northbound just past MD 85
Incident description for the following slide.

5. Units on Scene Lanes Closed Traveler Information Traffic Speeds
This is a snapshot of the incident timeline as captured by the CHART system and depicted by RITIS.
It provides information on the agencies involved, duration of lane blockage, DMS messages utilized, etc.
Active first responders are color-coded with red, blue, and brown representing fire service, police, and CHART patrol vehicles, respectively. Light blue represents “Transcom”.
Note that a Medevac helicopter was involved in the incident management process and required closure of all the lanes including the shoulder for over 15 minutes.

7. This is the home page of the Maryland 511 website.
Maryland’s 511 Travel Information Service provides useful, high-quality, comprehensive, and readily available and accessible travel information for multiple modes of transportation.
It is a multi-platform system that provides information via a menu-driven telephone service, Internet website (which you see here), mobile web platform, and social media services.
Maryland 511 provides information on incidents, modal availability, travel speed and time, roadway conditions, congestion, work zones, weather, planned events, and tourism.

8. Situational Awareness
This screenshot from 511 shows the incident report, traffic speed impacts, and a live video of the incident recovery in progress.
Situational Awareness

9. Regional Integrated Transportation Information System (RITIS)
A Real-Time and Archived Repository of Highway Conditions and Events
SHA works with the University of Maryland in developing tools to analyze the data collected by Transportation Management Systems. RITIS collects, archives and provides visualization of the data.

10. Regional Integrated Transportation Information System (RITIS)
Analysis of Incident “Hot Spots”
This is a “heat graph” showing areas that experience a greater frequency of incidents.

11. Clicking on an Incident brings up the details
What happened? Where did this happen? Who notified us? How far is the queue? What are the SOPs I should follow?

12. What types of vehicles? What are the roadway conditions?
What lanes are closed?

13. Who is nearby?
Have they been dispatched to the Incident?
Have they arrived?
Do they have mobile camera capability?

14. What permanent cameras, message signs and radio stations are nearby
What permanent cameras, message signs and radio stations are nearby? Within 3 miles? Within 5 miles?

15. Who should be looking at the video from the scene?
What messages should be on the message signs?

16. Incident Management 24 Hours / 7 Days per Week Operation
“Clear the Road Policy”
Close Coordination with State Police
Emergency Traffic Patrols (ETP’s)
Emergency Response Units (ERU’s)
Approximately 43 units on the Road
CHART Operations Centers
CHART’s TOC’s provide tactical command of incident responses.
ETP’s support the “Clear the Road Policy” and carry equipment to make minor vehicle repairs at the roadside.
The “Clear the Road Policy” helps to restore traffic to normal conditions as soon as possible; where safety is not an issue, removing the vehicle from the travel lane is a top priority .
ERU’s perform a higher level of incident management, deploying detour routes and establishing traffic control.
Sand trucks and front loaders also provide support for the “Clear the Road Policy.”

17. CHART Performance Evaluation
Since 1990, CHART has provided more than 490,000 assists
In the same period, CHART has responded to more than 230,000 incidents
In 2015, CHART handled over 115,000 events saving approximately $1.36 Billion in delay and fuel costs
Since 1990, CHART has provided more than 490,000 “assists,” which consist of providing aid to a stranded motorist, relocating disabled vehicles to the shoulder, or removing debris from the roadway.
In the same period, CHART has responded to more than 230,000 “incidents.” An “incident response” is defined as providing traffic control and coordination at an incident scene involving a crash or a lane blockage.
“Events” refer to not only assists and incident responses but also to special events (such as professional and collegiate sporting events and holiday events (Fourth of July)), weather events, planned closures and other roadway activities for which CHART is needed.

18. CHART Performance Evaluation
Since 1999, the University of Maryland has developed an annual performance evaluation for the CHART TIM program. Data include:
CHART’s response and clearance times and the average incident duration due to CHART
Benefits of the CHART program (e.g., reduction in delay, user cost savings, as well as reductions in fuel consumption and emissions)
These data were used and extrapolated to develop a detailed justification for CHART’s TIM patrol expansion, which I will discuss toward the end of this presentation.
The University of Maryland Department of Civil and Environmental Engineering prepares a yearly evaluation of the CHART program. The University receives the CHART data in a real-time data feed as well as a nightly database DUMP file from CHART and extracts all incident data from the database and adds roadway volume data and roadway link location data to the incident information of the database.
The University of Maryland compiles incident reports for all incidents in the database. Incident reports are grouped together into categories of similar nature. The different categories of incidents are then matched with similar incidents and a sample event, based on real-world data, is modeled using computer simulation software (CORSIM). Calibration of the required equations is based on samples of actual incident scenarios simulated with CORSIM. Formulas used are derived from samplings of models that are a significant size of a large total population of records (more than 35,000 incidents or requests for driver assistance per year). The annual CHART evaluation is based on the University of Maryland's complete analysis of all incidents in the database.
In addition to the number of assists and incident responses, the evaluation records other benefits the CHART program provides to the traveling public such as the reduction in delay (a value calculated to determine the overall reduction in incident delays as a result of the CHART program), an economic measure (user benefits or user cost savings that result from CHART’s activities), and the number of potential and secondary incidents that were prevented due to CHART’s performance.

19. This graph depicts the total events that CHART has handled per year since 2001.

Joey, this is a slide that Jason developed. While it may be self-explanatory, I don’t have any context here. Sorry.

24. Expansion Proposal
This was the proposal for the CHART TIM Patrol Expansion.

25. Justification for TIM Patrol Expansion
Established Benefits of CHART Program
High Rates of Accidents during Nighttime Hours and Weekends in Existing Patrol Areas
Population Growth
Permanent vs. Contractual Staff
Overnight and Weekend Pilot Patrol Program
In order for an expansion to be made to an existing program, such as the CHART TIM program, a justification is required. The data shown here were presented, along with other information, to the CHART Board of Directors for its approval. Once the CHART Board approved the expansion, the next stage in the approval process was for CHART to complete the required SHA form(s) to formally request the expansion.
