Joanna Reagle

“I enjoy the softer side of engineering – bringing people together to exchange ideas and solve problems so that everyone can benefit. There’s nothing quite like working as a team to overcome transportation challenges for the community at large.”

Joanna approaches every project with a client-focused, proactive and positive attitude. It’s her infectious smile, outgoing personality and exceptional communication skills that make her a pleasure to work with.

Joanna is responsible for KMJ’s public and stakeholder engagement practice. She approaches every project with a client-focused, proactive and positive attitude.

Martin Williams, PE

“A simple thing I appreciate about engineering is the impromptu Q&A session in the field with concerned neighbors who ask what I’m doing. They’re genuinely curious and typically thankful since they have a vested interest in project success. It really adds meaning to our work when you add a human face to it.”

A Senior Engineer, Marty has been involved in myriad studies and projects, ranging from traffic signal design, arterial and intersection analysis, to assessing and cataloging historic streets in the City of Philadelphia.

Always the cool analyst, Marty shines in his meticulous attention to both macro-scale project elements and the nitty-gritty details. As a young engineer and master of technology, Marty produces work that is polished with cutting-edge techniques and modern methodology. His focused and collected approach to engineering leads to project accuracy and consistency.

“Civil engineering isn’t a static field. Roads, bridges, and intersections have been around for thousands of years, but they’re evolving every day. We use new tools, new techniques, and new methods to create and augment them. It’s the synthesis of so many different disciplines that unify to create a grand outcome – infrastructure that millions of people use every day.”

Marty earned his bachelor of science degree in civil engineering from Drexel University in Philadelphia and is a member of American Society of Highway Engineers and the Institute of Transportation Engineers, Mid-Atlantic Section.

Outside the office, Marty can be found traipsing about in the wilderness up and down the east coast, often accompanied by his dog Xena. Always up for a challenge, he’s been outfitting some serious gear to conquer more technical climbs that involve things like icy waterfalls and frigid weather.

Justin Ferri

When he’s not immersed in cyberspace, Justin can be found dabbling at the ice hockey rink, a proud 25+ year vet. He’s also an emerging molecular gastronomist and seasoned brewer, putting his biochemistry background to good use.


Transportation Engineering

Mobility is a key driver to the economic engine in a region. KMJ has been an innovative contributor to transportation engineering projects that improve mobility in the region and beyond. We have successfully completed projects in the realm of traffic engineering and signal design, safety improvements and transportation planning for PennDOT, The City of Philadelphia, DelDOT, NJDOT, the Philadelphia International Airport, and others.


Outreach is second only to the project design in delivering a successful project. Involving stakeholders in the process along with project designers provides the opportunity to gain mutual understanding while creating a more inclusive product. KMJ has a keen understanding of these needs and an approach to ferret out/drill down to generate a productive and effective program that engages the project stakeholders and provides the designers with valuable information. We take great care to assure the needs of the lay person are addressed with respect and compassion. Above all, our transportation experience enables us to be the valuable third-party interface to the engineers.

Software and Systems Training, Testing and Support

A successful training program helps the user succeed. KMJ meshes its technical and communication skills to develop training programs to accomplish this goal. By understanding the training material and the audience, KMJ creates a tailored environment that provides a positive and effective learning experience. We’ve used this process for software training and development, hardware (DMS) training and customer service training (TMC). Software application users need timely, informative and responsive technical support to succeed! KMJ has a knack for understanding the users’ needs and provides it for national transportation data programs. On occasion this includes training, presentations and hands-on guidance.
