CITY ROUTE OPTIMIZATION FOR LESS-THAN-TRUCKLOAD MOVEMENTS.

City Route Optimization (CRO) is a logistics technology developed and implemented by ArcBest® for their
less-than-truckload (LTL) carrier, ABF Freight®. With over 40,000 assets operating out of 240 service centers
across North America, ABF picks up and delivers thousands of shipments each day in their city operations,
serving customers with efficient pickup and delivery processes to keep their supply chains moving.

The goal of CRO technology is to optimize ABF's LTL operations — striving to increase productivity, improve
customer experiences and reduce environmental impact. Created internally by data scientists and
operational specialists, it uses machine learning and artificial intelligence to create algorithms that build
optimized city routes by leveraging legacy knowledge and information on existing routes. CRO's projected

outcomes were improved sustainability and efficiencies for ABF's city operations and their customers as well
as improved experiences for ABF drivers.

Building City Route Optimization

For ABF's city operations to run smoothly, each morning, a team of inbound supervisors' plan driver
schedules for the day. In the past, they coordinated these complex routes, using legacy knowledge and data
from past shipping patterns, to develop a schedule that enabled them to deliver and pick up as much freight
as possible on that day. While historically this was effective, urban growth and expansion, combined with
supply chain changes over time, have made route planning increasingly more complex. This resulted in
challenges that impact customer satisfaction, including additional shipping fees, mediocre customer
experiences and a gradually increasing environmental impact.

As a trusted partner to their LTL customers, ArcBest leveraged technology and innovation to create a
solution that minimizes costs, optimizes routes, and better deploys the ABF fleet. In 2020, ArcBest's
Technologies team began exploring a large, diverse set of historical and current city and fleet operations
data and identified opportunities to enhance the utilization of the company's daily capacity while reducing
miles driven.

In the early stages, ArcBest looked for external support but discovered there was no technology available
with the capabilities needed to optimize routes for ABF's expansive, nationwide network. Due to scheduled
delivery times and pickup requests that filter in throughout the day, their operations became complicated to
the point that external vendors couldn't provide a solution. The company needed an analytical approach that
incorporated delivery and pickup into a single model, enabling them to reduce expenses, improve service
and ultimately increase productivity with the same number of drivers. This pushed the teams to brainstorm
internally and build what they needed using their expert data scientists and operational specialists.

ArcBest relied heavily on applying the concept of the Traveling Salesman Problem — examining the daily
routes of a group of ABF service centers and identifying more efficient routes to reduce miles driven
between each stop. During this time, analysts also began using hexagonal geospatial technology — an
innovative approach for determining geographic zones compared to standard ZIP codes. Hexagonal zoning
technology enabled every point of latitude and longitude to be mapped throughout the network. Combining
this with large, diverse datasets from each service center into a single database and using rigorous statistical
A/B testing, promising results were achieved.

After a year of research and development, in late 2021, ABF Freight began testing Phase 1 — which involved
prescribing daily static routes based on historical trends and data mined from each service center, tracking
when the prescribed routes were used and analyzing how they improved the local freight environment. They
started testing at one location and then added additional service centers until they were testing at 10
facilities. After monitoring these locations and seeing positive results, the company began a broader rollout
throughout 2022, and today, it's using CRO technology at every ABF service center, completely transforming
ABF's city operations.

OUTCOME/ RESULT/ IMPACT

% Since fully implementing CRO, ABF has seen positive

business impacts including denser city routes, fewer miles
driven, less fuel consumption, reduced carbon footprint and
increased productivity.

•	Efficiency gains and optimized routes enabled ABF
Freight to handle more shipments and provide capacity
for growth.

% Optimizing LTL delivery routes has the co-benefit of relieving
some road congestion.

•	CRO's optimization of ABF's LTL network resulted in a
projected 1.5 percent increase in street productivity and a
17 percent reduction in using local cartage agents. (1)

% CRO's optimization resulted in a cost savings of over $13M
annually, with additional significant financial savings
anticipated as refinement of the process continues.

% Improved fleet deployment impacts equipment pools,
enabling ArcBest to better service new and existing
customers by offering the right capacity at the right time. This
also creates opportunities for intermodal shifts where the
movement requirements align with rail characteristics.

| Call-Out Benefit

By making LTL deliveries
more efficient using route
optimization technology,
freight customers can also
benefit by lowering their
overall carbon footprint.

"LEADING THE WAY": TRANSFERABLE LESSON LEARNED.

As ArcBest developed CRO, it discovered a tension between theory and practice and a need to allow
feedback loops from operations to increase model fidelity. The teams worked together diligently to
determine an appropriate balance between the most efficient steps and incorporating employee feedback
throughout the iterative development process — which involved a heavy emphasis on compliance reporting
from ABF's city dispatchers — to ensure CRO would benefit everyone involved or using the company's city
operations.

ArcBest and ABF are actively piloting additional phases, which includes plans for increased real-time
visibility. The technology and algorithms being built will consider daily fluctuations in freight levels and
freight characteristics, providing an even greater opportunity to optimize routes and improve productivity.

Route optimization approaches that use postal zip codes or "drawing circles" to determine routes don't
account for natural barriers, create unrealistic delivery areas, or leave gaps in coverage. The use of a
"hexagonal zone" approach can create delivery zones that better represent the reality on the ground and
better align with the capabilities of the facility servicing the area.

CONCLUSION

Route optimization can have a significant impact on the efficiency of deliveries with co-benefits of reduced
road congestion. Route optimazation tools can be expected to have even greater impacts on freight
efficiency as the algorithms are refined and opportunities for incorporating real-time data bear fruit.

SmartWay Profiles in Leadership

Profiles in Leadership is SmartWay's newest recognition initiative. Beginning this year, EPA will
recognize freight sustainability leadership actions of SmartWay Affiliates and eligible SmartWay
Partners (Logistics companies, Air carriers, Barge carriers and Rail carriers). EPA developed this
recognition concept after hearing that Affiliates and Partners would like to see greater opportunities
for recognition of sector leadership. EPA SmartWay created this new type of recognition to provide
additional opportunity for advancing freight transportation sustainability.

SmartWay defines leadership in this context as the ability to drive change, influence industry, lead
freight efficiency performance, and sustain freight-related environmental excellence. Profiles in
Leadership is an official SmartWay program acknowledgement of leadership demonstrated by
investments that are strategic, financial, and innovative, which will yield future environmental and
efficiency benefits.
