I-95 CORRIDOR COALITION – THE EASTERN TRANSPORTATION COALITION EXECUTIVE BOARD WEBCAST
April 22, 2020
Notes
Attachment: • Meeting presentation slides • Overview of Maryland SafeZone Program
1. Welcome and Introductions – Trish Hendren welcomed the participants to this webcast of the I-95
Corridor Coalition’s Executive Board. A roll call was taken and is provided with these minutes.
2. Getting Information to Staff and Stakeholders – The Coalition continuously gets information into the hands of your staff and stakeholders through a wide range of data, tools, best practice sharing, experience exchanges and staff expertise. The need for information is particularly acute during the COVID pandemic. Following are a few examples of such resources available through the Coalition and Coalition partners:
a. I-95CC TETC Commercial Vehicle Portal (https://i95coalition.org/commercial-vehicle-
operations-online-portal/) – This page, now heavily utilized, is a single location to access information of interest to motor carriers. To ensure direct and current information, the site provides links to commercial vehicle-specific state and federal agencies. In addition to linking to I-95 Corridor Coalition agencies’ Travel Information sites, the Portal also contains information on Commercial Vehicle Operating, Credentialing, Registration, Taxation, and Permitting Requirements, Commercial Driver Licensing, Traveler Truck Parking and Weigh Stations, Tolling Information, and Motor Truck Associations for each of the I-95 Coalition Member States.
b. COVID-19 Impact Analysis (https://data.covid.umd.edu) - Researchers at the University of Maryland (UMD) are exploring how social distancing and stay-at-home orders are affecting travel behavior and spread of the coronavirus. With privacy-protected data from mobile devices, government agencies, health care systems, and other sources, the University is also studying the multifaceted impact of COVID-19 on mobility, health, economy, and society. This interactive analytics platform makes the data and research findings available to other researchers, agencies, non-profits, media, and the general public. The platform contains national, state and county information, and will evolve and expand over time as new data and impact metrics are computed and additional visualizations are developed.
c. National Traffic Volume Synopsis (https://inrix.com/blog/2020/04/covid19-us-traffic-
volume-synopsis-5/) – Inrix provides a weekly review of changes in road traffic demand in the United States from the COVID-19 virus spread and our collective response. There is a high interest in how volume is changing, and how data is gathered from passenger vehicles, local fleets and long-haul trucks.
d. Optimism in Face of Crisis (https://www.quinnthomas.com/2020/04/washingtonians-
surveyed-about-coronavirus/) – A recent survey, conducted in Washington State indicated that people are expressing support and resolve throughout the coronavirus situation. From senior citizens suffering the biggest health impacts, to young people suffering financially, there is a general sense that we’re all in this together. Results showed high marks for key
2 | P a g e
institutions, with residents giving high marks to medical facilities and agencies, and to the governor. And with 90 percent of residents social distancing, people feel the responsibility to do their part to get through this together. The Coalition will be administering a similar survey in North Carolina.
3. Continuing Key Program Work –The coronavirus has also highlighted the importance of how the Coalition continues to efficiently and effectively connect members to solutions through ongoing projects such as:
a. Volume and Turning Movement – The goal of this project is to provide network-wide
volume data where results can be used for AADT, ADT and real-time operations. Phase One (completed) developed a method to estimate volume from probe data; Phase Two will take the activity from the “Lab to the Street.” A workshop was held on April 21st to provide an update on the project and the results from two locations; approximately 100 individuals – representing 22 states – participated in the workshop.
b. Transportation Disruption and Disaster Statistics (TDADS) – (aka “Identifying and Quantifying Causes of Congestion”) The Coalition, in partnership with the UMD CATT Lab, is building a new analytical and operational tool to evaluate regional factors causing congestion, create an interactive and easily-accessible tool to put in the hands of decision-makers, and expand analysis to other modes (e.g., air and rail). The TDADS key project steps include categorizing a disruption once it is detected, identifying the source of the disruption, and assigning a user delay cost (a dollar value based on the duration and spatial extent of the congestion). Preliminary results were displayed for Maryland, illustrating the impact of recurrent congestion, incidents, weather, work zone, signals, holidays, and combinations thereof. Understanding the sources and impact of congestion helps with data-driven approaches for mitigation measures, such as capital projects, TSMO strategies, travel demand management strategies, etc.
c. Additional Funding for Training – With many agency employees working from home, the
Coalition has increased options and funding for online training during this period. Web-based courses are available through the Consortium for Innovative Transportation Education (CITE) and cover a wide-range of system management and operations courses. Examples of available courses include:
i. TSMO 101 – What is This TSMO Thing Anyway? ii. Program Planning for TSMO
iii. CMM Assessing Agency Capabilities Additional courses can be found at citeconsortium.org and interested Coalition members should contact Mai Quynh Le ([email protected]) for more information.
d. Inside the MAASTO Truck Parking Project – The Coalition held a learning session on March 13, 2020 – with representatives from 11 states – to hear about the Mid-America Association of State Transportation Officials (MAASTO) Regional Truck Parking Information and Management System (TPIMS). The TPIMS was designed to monitor truck parking availability and provide real-time information to truck drivers. Note: there was no capacity building under this effort. Funding for the TPIMS was acquired through a $25M Tiger Grant plus an additional $6.25 in Federal Funds. Each state (Indiana, Iowa, Kansas, Kentucky, Michigan, Minnesota, Ohio, and Wisconsin) received Federal funding with a portion set aside to Kansas DOT for the Concept of Operations, System Design and Regional Oversight. The states varied in approach to the project and various data-gathering technologies were used to detect facility utilization. Regardless of the approach selected by each state, the
3 | P a g e
information output was designed to be interoperable—an essential characteristic form the trucking perspective.
e. Connected and Autonomous Vehicles Regional Groups – In FY20, the Coalition launched three regional working groups to help build key relationships and to leverage diverse state-by-state approaches to preparing for and managing CAV on public facilities. The regional working groups are:
i. Northeast: ME, VT, MA, CT, RI ii. Mid-Atlantic: NY, PA, NJ, DE, MD, DC, VA
iii. Southeast: NC, TN, SC, GA, FL, AL
f. New England Transportation Consortium Grant: NE CAV Legal and Regulatory Assessment The Coalition supported the development of this grant proposal based on the NE CAV regional group meetings. Now that the grant has been awarded, the Coalition will continue to be engaged. The project work will include a multi-state legal and regulatory assessment related to issues which may impact connected/automated vehicle operations, and identify where consistency across state lines would facilitate testing and deployment. The areas to be explored include insurance coverage, vehicle credentialing, operator licensing, crash investigations, motor vehicle citations, commercial vehicle regulations, and pilot testing of emerging technologies.
4. Upcoming Coalition Activities (April – June 2020) – The following upcoming events were
highlighted:
a. Tolling Violation Enforcement Reciprocity Working Group (April 30) – This working group, comprised of toll agencies, DOTs, DMV, and key stakeholders, are meeting to further a multistate effort at collecting toll fees from out-of-state violators. The specific topic for the April 30 workshop is “Making it Easier to Pay” – a topic of particular importance as the shift to non-booth collection is accelerating.
b. Southern HOGs Regional Hurricane Prep Call (April 30) – As agencies prepare for the 2020 hurricane season, the Coalition’s Southern Highway Operations Group is bringing together representatives from VA, NC, SC, GA, FL, TN and AL to document the chains of command in communications, confirm the process for road closure notification, and highlight new technology to be used.
c. Probe Data Analytics User Group Meeting (May 7) – This user group meets regularly and,
at this next session, will hear from (1) Rhode Island Statewide Planning on using O-D data to better understand truck trips and diversion, and (2) District DOT on analyzing the effect of arterial management strategies.
d. Automated Work Zone and Protecting our Infrastructure Workshop (May 28) – This
learning session will feature presentations on Pennsylvania Turnpike’s Tuscarora Tunnel Traffic Management System and Maryland Transportation Authority’s Weigh in Motion System Integration.
e. Operations Academy Nominations (due June 1) – Nomination forms for the 2020
Operations Academy are due June 1. A select number of Coalition scholarships will be awarded to applicants from Coalition member agencies. NOTE: the 2020 Operations Academy will occur virtually.
4 | P a g e
f. STSFA Phase 5 Grant Application (due June 15) – The Coalition is submitting an application for the next (and last) round of grants under the USDOT’s Surface Transportation System Funding Alternatives Program. The Coalition has received grants under the first three phases to research the feasibility of a mileage-based user fee system. States interested in participating in the pilot programs should advise Trish Hendren as soon as possible to be included in the application for Phase 5.
g. Program Tracks’ Strategic Planning Session (June 16)– Coalition member agency
representatives will meet to develop work plan proposals, based on guidance provided by the Executive Board, for the upcoming fiscal year.
h. CAV Infrastructure Readiness Workshop (June 17) – This workshop (held virtually) will
explore the use of infrastructure readiness assessment methodologies in developing approach for determining a multi-state region’s readiness for automated vehicles. Funded by USDOT and with NREL as a partner, the Coalition will connect the work to practitioners.
i. Travel Information Services Meeting (June 17) – Bi-annual meeting (virtual) that will focus
on emerging technologies in travel information and how agencies are utilizing them for both passenger and commercial vehicles. Discussion will include NJDOT's use of Voice Assistance in the 511 System, Commercial Vehicle Safety Alerts, Emergency Ops: The HELP System State Updates (PA, GA, NJ, MD), PennDOT’s TSMO Performance Program and New and Traditional Media in Traveler Information.
j. FY21 Work Plan Development Schedule (April to June):
i. February 25 – The Executive Board set the strategic direction ii. April – The Coalition develops draft program concepts
iii. May – Coalition Members provide input via program calls iv. June 16 – Coalition-wide identification is made of cross-cutting issues v. June 24 – The Executive Board reviews and approves the FY21 Work Plan
k. The I-95 Corridor Coalition officially becomes The Eastern Transportation Coalition (July 1)
The Coalition will be rebranding with a new name, logo, website and look to better illustrate the expanded geographic region and breadth/depth of the program.
5. Member Discussion – DelDOT Secretary Jennifer Cohan moderated a discussion to determine (1)
the most pressing transportation challenges member agencies are facing today, and (2) the information needed to answer today’s questions. Five keys areas were raised and discussed:
a. Truckers have specific needs in transport during a pandemic, such as gross vehicle weight waivers, access to food and hand sanitizer at rest areas, and health and safety precautions for movement in a “hot zone.” Additionally, Truckers indicated they have received inadequate acknowledgement for their significant efforts to deliver goods (including medical supplies) during the pandemic.
b. Challenge with processing truck weight waivers and informing the motor carriers about what weight limits had been changed
c. With the increased demand on freight movement, MPOs are receiving more land use applications for distribution centers.
d. With lower traffic volume on roads, there has been a noticeable increase in speed – and, in some cases, resulting in more severe accidents
e. Growing desire to use cameras to improve work zone safety
5 | P a g e
In response to the Board discussion, it was suggested that the Coalition consider the following actions:
• (Underway) Draft a letter from Coalition CEO’s to State Motor Trucking Association Directors, ATA, TCA and OIDDA to express appreciation for the commitment of truckers to move essential products under challenging conditions
• Bring together the leaders of the State Motor Trucking Associations, key stakeholders and the DOTs to do an after-action review of lessons learned during COVID (e.g., what worked well, what didn’t work well)
• Develop an After-Action Review to document lessons learned, implementable solutions focused on operations, and share best practices regarding freight movement surrounding the pandemic.
• (Completed) Work with Commercial Vehicle Safety Alliance (CVSA) to post a repository for emergency declarations relevant to motor carrier transport – including weight restriction exemptions for all 50 states, Canada and Mexico on the Coalition’s CVO Portal (https://i95coalition.org/commercial-vehicle-operations-online-portal/)
• Reach out to transportation partners to determine if analysis has been done about speeding and the severity of crashes as a result of less traffic on the roadways during the state-at-home stage.
• (Completed) Share information about the Maryland SafeZone Program and authorizing legislation (see meeting attachment).
• Gather lessons learned and helpful strategies from states who have successfully passed (or not passed) legislation to allow for camera enforcement in work zones.
6. Today’s Ask – As a reminder, the Executive Board members are asked to:
a. Participate in Upcoming Activities – Participation in Coalition upcoming events is particularly helpful to keep agency staff engaged and aware during this time when many employees are working remotely.
b. Sign the WAZE letter (by May 31) – The letter, distributed earlier this month by Denise Markow, is seeking signatures of Executive Board members to request that WAZE provide easier digestible data for agencies’ use.
c. Operations Academy Nominations (by June 1) – There are a limited number of scholarships available to Coalition member agencies. Applications/nominations can be made through the Operations Academy website at operationsacademy.org.
d. STSFA Phase 5 Grant (ASAP, proposal due June 15) – This is the last round of the STSFA grant program, and an opportunity for states to get engaged in pilot testing, education/outreach, and evaluation of a mileage-based user fee system. Interested agencies should contact Trish Hendren ([email protected]) as soon as possible.
e. FY21 Work Plan Approval (June 24) – The Executive Board will be provided with a Coalition FY21 Work Plan for approval during a webinar to be held on June 24 at 9:00 AM Eastern.

THANK YOU!Connecting for Solutions
Maryland Department of Transportation State Highway Administration’s (MDOT SHA) Maryland SafeZones Program
On October 1, 2009, Transportation Article §21-810 of the Maryland Annotated Code became effective. This law allows the use of automated speed enforcement (ASE) equipment in work zones along expressways and controlled access highways with a posted speed limit of 45 miles per hour (mph) or more. Citations may be issued to registered owners of vehicles exceeding the posted work zone speed limit by 12 mph or more. The civil penalty set by the District Court for this violation is $40 and no points are assessed against the registered owner’s driving record. By law, an operator is required to be present at all times when the ASE equipment is actively enforcing. Regarding the ASE equipment, an annual calibration is required in addition to a daily self-test of the equipment prior to the start of each enforcement period. Additionally, it was required by law that the state only issue warnings for the first 30 days of the program. MDOT SHA issued warnings for 45 days and further goes beyond the requirements of the law to issue warnings for a 3-week period at new long term work zones. The Code of Maryland Regulations (COMAR) provides clarification on advanced notification requirements. COMAR 04.15.03 requires a minimum of 2 sets of signs, one on each side of the roadway, to be placed in advance of each ASE system. COMAR also requires the use of a speed display trailer that provides a digital reading of approaching vehicle speeds in advance of each ASE system. The intent of the speed display trailer is to prompt drivers to check their speedometers so that they can reduce their vehicle speed if necessary. The MDOT SHA Standards currently require the use of 4 sets of signs and 1 speed display trailer, exceeding the requirements in the law. MDOT SHA also maintains a website that displays ASE locations and provides general program information. ANALYSIS The MDOT SHA, Maryland Transportation Authority (MDTA) and Maryland State Police (MSP) launched the ASE program on October 1, 2009. Since then, driver compliance with the posted speed limit has increased. In 2010, approximately seven percent of drivers in SafeZones enforced work zones were exceeding the speed limit by 12 mph or more. Today, on average, one percent of drivers are receiving a citation, showing a nearly 90 percent reduction in the number of vehicles traveling 12 mph or more above the work zone speed limit. To date, ASE has been deployed at 92 locations statewide. Additional information: http://www.safezones.maryland.gov/mdlaw.html
