From traffic planning to highway and bridge design, HRG can tie together the varied elements of transportation design to maintain, improve and expand vital roadway networks for improved safety and superior traffic flow. Our staff has successfully navigated through the intricacies of hundreds of transportation projects of varying size and scope, delivering engineering solutions customized to fit each project’s unique needs.
Traffic Engineering
HRG’s comprehensive array of traffic engineering services includes traffic impact studies, traffic signal design, congestion management studies and transportation planning. Our traffic studies include an analysis of current and projected land use as well as thorough collection and analysis of existing traffic data. After identifying system requirements, we apply state-of-the-art software to design the most cost-effective traffic systems that maximize efficiency and promote safety. The results: innovative solutions that deliver improved traffic flow for many years to come.
Highway Design
Our transportation engineers have completed hundreds of roadway designs of varying size and complexity — from interstate interchanges to bituminous overlays of local road. Our experience includes engineering services for dozens of large-scale improvement projects to enhance safety and increase capacity along major arterial roadways and interstates throughout the region. In addition, as the retained engineer for dozens of local governments, we have vast experience with routine pavement rehabilitation and roadway maintenance assignments.
Bridge Engineering
Our engineers have completed more than 100 bridge replacements and rehabilitations. Our projects have ranged from locally sponsored, federally funded bridge replacements to state-owned, single- and multi-span structures traversing streams, highways and railroads. In addition, our Certified Bridge Safety Inspectors perform NBIS inspections to assess the physical integrity and structural adequacy of a wide variety of bridges.
Rail Engineering
Our staff provides comprehensive rail engineering services to private sector
companies who rely on rail for the transportation of their goods, public transit agencies providing enhanced multi-modal access, and railroad lines that transport freight for industry.
Primarily serving Class 1 and Class 2 railroads in the areas of mainline siding and freight yard expansions, we understand the fast-paced nature of your business and the dollars that depend on rapid response. Therefore, we provide quick turnaround on all plans and deliverables to keep your project on track.
Our capabilities include:
- feasibility studies
- track evaluations
- new track design and track rehabilitation
- construction management and inspection
- assistance in obtaining project funding
Technology To Maximize Efficiency
HRG delivers our services to you quickly and cost-effectively, using state-of-the-art design software including:
- Synchro® plus SimTraffic for signal timing, capacity analysis and traffic simulation. This software dramatically reduces the time it takes to optimize traffic signal timings and simulates traffic flow under various design scenarios in order to quickly select the best alternative without the need for costly and time-consuming
pilot studies.
- RISA 3-D for the structural analysis and design of trusses and frames. We also use a variety of other leading bridge design software packages for accuracy in the design, analysis, and rating of steel and concrete bridges, box culverts, abutments and retaining walls.
- AutoCAD and MicroStation InRoads to provide design plans in the platform of your choice in order to meet your internal operations needs. InRoads software has been specifically designed for the engineering of roadways, so it provides greater efficiency and superior analysis tools for this type of work.
