Lanham Engineering has performed on-call engineering services for the Franklin County Engineer’s Office for safety studies and traffic analysis since 2015. We have completed full studies or performed analysis on eleven different intersections. As a result of our studies, Franklin County has received ODOT funding for seven different roundabouts in the last several years.
Through ODOT’s Statewide Safety program, we served as a subconsultant under five different contracts with primes where we provided services ranging from traffic analysis support to full traffic studies. In Districts 2-7, we have worked on six safety studies, and in District 12, we have performed tasks on eight different projects.
As a first-time prime consultant with ODOT, Lanham Engineering was contracted to manage safety studies, abbreviated safety studies, and a data driven safety analysis along with two subconsultants. We primed a total of ten studies in Districts 5, 6, 8, and 9. We successfully managed up to four studies at a time and utilized both subconsultants on some tasks.
Our team performed corridor studies for several jurisdictions in Central Ohio. In Delaware County along South Old State Road, we developed future year traffic volumes in order to determine future roadway cross-sections and traffic control along the corridor. For the City of Columbus, we provided analysis for capacity, safety, and parking along West Broad Street to determine future needs for the Hilltop Streetscape Study Phase 1.
In addition, Lanham studied US-33 between Nottingham Road and Canterbury Road for the City of Upper Arlington. We performed crash and capacity analysis along with signal and turn lane warrants to determine how best to address existing issues and encourage future redevelopment.
We have provided traffic impact studies for several school locations since the company’s founding in 2013. Urbana City Schools required a study to be approved by ODOT for a new building along the south side of SR-68 where a new PK-8 school will replace five other schools.
For Lancaster City Schools, our team studied the north side of the city where a new junior high school will be built. Most recently in Gahanna, a replacement elementary school will be added to an existing middle school property for Gahanna-Jefferson City Schools.
In ODOT District 12, we performed various traffic services as a subconsultant including a signal warrant review for Strongsville, a speed zone study for GEA-168, GEA-322 signal warrant analysis and a safety analysis and funding application at US-422 at SR-700.
We partnered with Carpenter Marty Transportation to provide engineering services for the City of Columbus downtown area. The first task was a unique before and after study for bicycle queue boxes which were added for cyclists to make two-stage left turns at intersections along one-way streets as part of a request to experiment through FHWA.
The project involved data collection which included traffic counts, tracking bicycle movements, and analysis on the use of the queue boxes. The second task was updating the City’s downtown VISUM model used for improvements and changes to the roadways and land use over the past six years.
Lanham Engineering performed various support tasks for STW Signal Corridor Timing projects as a subconsultant in ODOT Districts 1, 2, 6, and 11. Corridor timing included data collection, field visits, travel time runs and synchro analysis in Wooster, Union, Allen, and Belmont counties.
As a subconsultant on back-to-back contracts, Lanham Engineering provided traffic engineering services under the City of Columbus Safety Studies contracts. We completed tasks involving bike lane layouts on 11 th Ave, analysis support for a safety study at the Georgesville/Hall intersection, cursory safety reviews at Cleveland/11 th Ave and McCutcheon/Stelzer, and full traffic safety studies on Refugee Road at Winchester Pike and Cleveland/Hudson.
Parsons Avenue between Broad Street to Franklin Street, part of the Olde Towne Quarter on the east side of Columbus, needed a streetscape facelift including new bike lanes and reconstructed signals at two intersections with ADA compliant components. We designed two mast arm signals including interconnect to City of Columbus standards with ADA compliant features with another subconsultant as the independent signal reviewer. The team received an ODOT Consultant Evaluation Score of 96% in January 2017 and construction was completed in Spring 2018.
Our team assisted EMH&T providing signal and traffic control design services including igning and pavement markings as part of a safety design contract. The two locations which were studied showed the need for safety improvements included striping modifications and a redesign of a three-legged intersection transformed into a more traditional design. Lanham Engineering redesigned the two existing span wire signals to mast arms for greater visibility with ADA compliant pedestrian features as well as the traffic control design components.
We are partnered with Crawford, Murphy & Tilly to provide engineering services for the City of Columbus on a task order contract. The largest task was to design curb extensions at five locations in Franklinton in order to improve pedestrian access and enhance aesthetics.
Our portion of the project included performing turning radius analysis using Autoturn software and creating exhibits to show suggested curb locations. We also prepared the traffic control plan sheets for the signing and pavement marking changes required for the design. Another task included signing, marking, and MOT design with a pedestrian detour for a sidewalk widening/replacement along 3 rd Avenue at Perry Street.
Lanham Engineering worked as a subconsultant to GPD Group where we designed signal modifications at four intersections in ODOT District 4 at the I-76 interchanges with West State Street and SR-619 in Barberton. They were closely spaced which created capacity deficiencies and safety problems. The interchange modification project created collector-distributor roads between the interchanges which allowed for better flow and less weaving on the mainline.
The I-71 corridor between 5 th Avenue and SR-161 often experiences congestion and a high frequency of crashes during peak hours. This project will study the feasibility of adding a hard shoulder running lane during those hours to help ease congestion and increase safety. Our role is crash analysis and evaluating the safety performance of several alternatives as a subconsultant to Gannett Fleming.
In ODOT District 12, Martin Luther King Jr. Drive in Cleveland is a three-lane minor arterial road which experienced high crash rates at its interchanges with I-90/SR-2. Our portion of this safety improvement was to develop plans for the signing and pavement marking improvements along the corridor as a subconsultant to TRC Engineers.
In our first design-build project, we partnered with Kokosing and Michael Baker to prepare signal plans for four intersections along the new Opportunity Corridor roadway in District 12. This final section of CUY-10 will connect I-490/I-77 and University Circle, and required coordination with the City of Cleveland.
US-62 between SR-43 and Nimishillen Creek was experiencing high crash rates and congestion through the existing signalized 5-lane arterial. This project converts the corridor to a 4-lane divided limited access section. Lanham Engineering is providing signal and traffic control design services for this corridor for TranSystems, our prime consultant. We are also currently learning and performing roadway design along a frontage road through the DBE development program.
This current DBE development project has allowed us to learn freeway drainage and BMP design, as well as refining our MOT design skills under the guidance of TranSystems, our prime consultant. We are also providing traffic control design services for this bridge replacement project.
This repeat prime consultant contract pairs Lanham Engineering with three subconsultants to deliver safety studies for ODOT. The contract focuses on studies for local municipalities throughout the state and includes both traditional safety studies and road safety audits.
The I-71 corridor between 5 th Avenue and SR-161 often experience congestion and a high frequency of crashes during peak hours. This project will study the feasibility of adding a hard shoulder running lane during those hours to help ease congestion and increase safety. Our role is crash analysis and evaluating the safety performance of several alternatives as a subconsultant to Gannett Fleming.
The purpose of this contract is to develop certified traffic on a task order basis for various projects throughout the state. The first two tasks involved alternatives to determine the best location for a new interchange along US-33 in Fairfield County. Our current task is to develop certified traffic for the FRA-71 HSR feasibility study.
Lanham Engineering is working with Arcadis to provide construction plans for the reconstruction of Fishinger Road and addition of shared use path between Mountview Road and Tremont Road in Upper Arlington, Ohio. Our portion of work includes signing/pavement marking design for the entire corridor and signal design/modifications for the Mountview Road and Reed Road intersections.

The purpose of this study was to evaluate existing capacity and determine future traffic demand for Lane Avenue between Riverside Drive and SR-315. As part of a larger effort to evaluate the future needs of the corridor, this study evaluates future capacity needs and provides recommend improvements for the short and medium term to provide a safe and efficient corridor for all modes of transportation.
