In Florida effective transportation facilities are critical to commerce, tourism, economic development, as well as the lifestyle we have grown accustomed to as Floridians. As Florida grows transportation issues become more important than ever. Our transportation group understands this and is ready to address the challenges we face. This group consists of two primary teams; design and construction engineering and inspection (CEI). Working in concert with our other in-house disciplines, the traveling public and the client, our transportation group has enjoyed a successful history of providing comprehensive transportation services.
What We Provide
Johnson Engineering has built an impressive portfolio of roadway design projects over the years. Our Transportation team boasts engineers and designers dedicated exclusively to Transportation Design. Our design experience includes developing new roadways, widening existing roadways and various minor roadway improvements for state, local and private facilities. Our team is FDOT prequalified in numerous areas. We are well trained and very familiar with current industry standardsand typical FDOT design practices and procedures. By providing much of the roadway support services in-house such as survey, drainage, environmental, utilities and construction engineering and inspection (CEI), we are able to provide our clients a complete and comprehensive design effort on every project.
The reliable mobility afforded to us by our existing roadway network provides is often taken for granted. Maintaining our infrastructure is critical not only to commerce and the movement of goods, but also to our personal wellbeing and safety. Commonly referred to as “3R” projects, the Resurfacing, Rehabilitation, and Restoration of existing roadways are a common and recurring need. Design elements often include existing pavement condition survey, pavement section analyses, milling and resurfacing, cross slope correctio, shoulder addition and safety improvements. Alternative treatments such as Full Depth Reclamation, in-place recycling and various sealing treatments can also be useful. There are many treatment options that must be carefully considered and appropriately applied to make sure we are getting the most out of our roadways and our maintenance funds.
Traffic Control at intersections can be effectively achieved with Traffic Signals. Our design team is adept, and FDOT pre-qualified, in providing signalization design. Proper signalization design must consider vehicular, bicycle and pedestrian traffic. It is important to coordinate these movements and optimize the timings to ensure safe and efficient intersection operation with minimal delays. Our team can provide signalization services including new signals, modification of existing signals, incorporation of pedestrian signals, signal timing analysis as well as signal warrant analyses.
Proper illumination of our roadway networks is critical for the safety of the traveling public. Various state requirements set for the minimum illumination criteria to provide sufficient light in a smooth and consistent fashion. With so many lighting options available today it can be challenging to select the best fit for your project. A computerized photometric analysis is performed to assess and determine the best combination of luminaire, pole and arm to provide the appropriate amount of light without additional wasted costs.
You cannot appropriately design roads without an understanding of the volumes and needs of the traffic they are intended to convey. We provide in-house data collection with pneumatic tube counters placed on the roadways to detect actual volumes, distribution, truck percentage and speeds of existing traffic. With real data we can then analyze that traffic to determine what improvements are really needed and what their expected benefit will be. Our team can provide a wide range of Traffic Analysis services including: signal and turn lane warrant analyses, volumetric and operational analyses, gap/delay studies, parking capacity analyses, speed studies, and Traffic Impact Studies (TIS) for both rezoning and development purposes.
Another popular and very effective form of intersection traffic control is the modern roundabout. The design of Modern Roundabouts has been much studied and improved, in the United States and in Florida, in recent years leading to increased safety, improved design and better understanding by the traveling public. Properly designed modern roundabout are very effective in their sheer simplicity, by removing left-turns, minimizing conflict points and providing slower, controlled passage through an intersection. While they have numerous benefits, the modern roundabout is not a one size fits all solution as it requires more right of way with its larger footprint and has reduced functionality at high traffic volumes. Our team is experienced in the design and development of modern roundabouts, when they should be used and when they shouldn’t.
Johnson Engineering’s long history has given us the unique insight that comes only with experience. We have seen the impact transportation facilities can have on a community, both positive and negative. By remaining mindful of our past, we can better prepare for our future. Planning transportation facilities today is not just about providing vehicular capacity. It’s not just adding another swath of pavement. Proper corridor planning is about overall mobility including vehicular, bicycle, pedestrian and mass transit. Today’s transportation planning efforts must consider sustainability while balancing the needs of commerce, personal mobility, our environment and the aesthetics and functionality it brings to our community. Our team has considerable experience in corridor planning, route analyses, corridor beautification and enhancement and Complete Street retrofits. Our roadway engineers work closely with our planners, landscape architects and ecologists to provide the mobility options we need in a manner our children can be proud of.
In today’s climate, accommodating our transportation needs has evolved beyond simply addressing vehicular capacity on our roadways. With persistent congestion multi-modal transportation alternatives are becoming increasingly more popular. Our transportation design services include a strong emphasis on the design of bicycle. transit, and pedestrian facilities including sidewalks, bus stop boarding & alighting, bike lanes, and multi-use paths. The development of these facilities is supported by our in-house services including roadway design, land planning and landscape architecture. As State and Federal funding are often available for such projects, we are also very familiar with the Federal Transit Administration (FTA) and FDOT Local Agency Program (LAP) procedures and compliance requirements required for such funding opportunities.
