I-105 Integrated Corridor Management Project
The I-105 and I-405 corridors are vital transportation arteries that link California communities, the Inglewood Entertainment District and the Los Angeles International Airport (LAX). Serving both passenger and goods movement vehicles, the corridors are essential components of the regional, statewide and national transportation system.
In an effort to minimize congestion and ease travel along the I-105 corridor from Sepulveda Boulevard to I-110, LA Metro’s I-105 Integrated Corridor Management (ICM) project implements ITS strategies to manage the capacity of a corridor using new and existing technologies to lessen the impact of traffic incidents.
Through HNTB’s application of sound systems engineering to deliver the concept of operations, the project will deliver near-term benefits of improved mobility, safety and air quality to the communities within the I-105 corridor. By using integrated technologies and proactive response strategies, the I-105 ICM project will better manage congestion during incidents and emergencies, providing seamless and more efficient transportation.
Smart Columbus
The City of Columbus, Ohio, completed its fiveyear Smart Columbus program, which aimed to demonstrate how an intelligent transportation system (ITS) and equitable access to transportation can have positive impacts on everyday challenges faced by cities.
HNTB was part of the Smart Columbus team from its early stages, supporting the city in developing its winning final application for the $40 million U.S. DOT Smart City Challenge. HNTB then developed a five-year ITS program management contract to help deliver Smart Columbus.
Opportunity and mobility as an equalizer for all residents was a primary goal of the program.
Accessibility analysis shows that the program expanded the geographic area reachable by a traveler within 30 minutes, providing access to more than 20,000 jobs and more than 3,000 healthcare services.

American Center for Mobility
A unique, world-class testing facility is taking the future of automated mobility forward.
Listed as one of the U.S. Department of Transportation’s 10 designated proving ground pilot sites, the American Center for Mobility (ACM) is a first-of-its-kind non-profit testing, education and product development facility centered on connected and automated vehicles as well as other mobility technologies.
To support in the delivery of a site that safely tests and develops innovative mobility solutions, HNTB served the American Center for Mobility as the primary consultant, performing design and construction engineering and inspection services. This role extended to the ACM’s High-Speed Loop as well as the ACM’s Urban Environment, where automated vehicles and intelligent transportation infrastructure can be tested under various real-world traffic scenarios.
Pennsylvania DOT Electric Vehicle Mobility
To help the state expand its Electric Vehicle (EV) strategy with clear equity and climate goals, HNTB led the development of the statewide EV Mobility Plan for the Pennsylvania Department of Transportation. The plan was incorporated into the state’s EV Infrastructure Deployment Plan, a requirement to receive funds from the National Electric Vehicle Infrastructure Formula Program.
Understanding other states’ EV strategies as well as U.S. EPA and the National Renewable Energy Laboratory best practices, HNTB incorporated stateof-the-art information into the plan. In addition, HNTB assessed industry trends and technologies and developed a process to estimate air quality to forecast expected benefits from EV adoption.
The study included an analysis of the state’s current network of charging locations and facilities to determine gaps — especially for interstate travel, routes of significance and corridors to 326 destinations.
DriveOhio Electric Vehicle Charging Study
DriveOhio, an Ohio Department of Transportation initiative dedicated to advancing smart mobility, prioritized advancing the state’s electric vehicle infrastructure to give local and visiting EV drivers better access to charging facilities statewide.
HNTB collaborated with a multitude of state agencies to develop a data-driven, statewide strategy with an eye toward emerging EV charging technologies and trends. The goal was to better connect intercity travel and tourism while preparing Ohio’s roadways for a future with more EV drivers. HNTB also worked with utility providers and cooperatives to identify sites with access to adequate power.
The study identified charging station gaps and suggested new charging station locations that could be accessed quickly and easily along Ohio’s interstate highway corridors, at major attractions and at state facilities. Key benchmarks and outcomes for installation were developed to keep the project on target.
The study is a roadmap to create a more robust statewide network of charging stations that reduce EV range anxiety, connect more destinations and support Ohio’s goal to increase its smart mobility.
MAASTO Truck Parking Information Management System
MAASTO’s Truck Parking Information Management System (TPIMS) is a federally funded mobility solution that’s providing truck drivers, fleet managers and owner-operators with up-tothe-minute parking information along the major freight corridors throughout the eight MAASTO member states.
HNTB collaborated with the MAASTO regional partnering states as general engineering consultant. With more than 130 public and private sites, the project utilizes dynamic message signs, smart phone applications, traveler information sites and other means at rest areas and participating private truck stops across the MAASTO region.
The eight partner states and the Federal Highway Administration anticipate TPIMS will continue to improve the safety and efficiency of America’s freight network. With support from HNTB’s staff, MAASTO’s successful grant application was able to heavily contribute to the $35 million in state and federal funding attributed to the first-of-itskind transportation system.
