Jammed! Poorly planned traffic designs can create conditions that are prone to crashes and inconveniences. We put the brakes on traffic issues with thoughtful planning and field-proven methodologies. Precision traffic engineering services and transportation planning studies are critical to master planning, new development, public safety and the effective movement of vehicles and pedestrians along a roadway or within a parking lot.


A unique aspect of Choice One’s traffic engineering services is the direct, hands-on, in-the-field experience our staff has. Whether it is working inside a controller cabinet, laying out pavement markings, or performing on-site analysis for many different types of studies, we have the knowledge to help!

Our Traffic Engineering Includes:


Traffic Signal Design:

  • Analyzation and design of the type, functionality, detection, timing, etc., of an individual traffic signal.

Traffic Signal Systems Design:

  • Analyzation and design of the type, functionality, detection, communications, timing, etc., of traffic signals integrated into an interconnected central system.

Traffic Impact Studies:

  • Study performed to determine the immediate and future impacts of a new or expanding development on the existing surrounding roadway network.

Traffic Signal Warrant Analysis:

  • Analysis of a traffic signal to determine it is warranted (as defined by the DOT) for purposes of improvement, installation, or removal.

Traffic Data Collection:

  • Collection of traffic data for analysis including vehicle counts, turning counts, and pedestrian counts.

Access Management:

  • Review and improvement design of driveway/street access along a specified route or intersection to improve safety and efficiency.

Speed Studies:

  • Study of the optimal safe speed for a particular stretch of roadway, which includes aspects such as the capacity of the roadway, sight distance, and points of access.

Safety Studies:

  • Study of a particular roadway corridor or intersection that has been prone to vehicular and/or pedestrian accidents and determination of countermeasures the help reduce accidents in the future.

Sign Maintenance and Management:

  • Determination of appropriate signage as dictated by the local DOT and development of a plan/schedule for regular maintenance and replacement.

Sight Distance Studies:

  • Study of roadway intersection or roadway access based on a driver’s or pedestrian’s ability to see oncoming vehicular or pedestrian traffic.

Interchange Modification/Operation Studies:

  • Operational analysis of the highway interchange due to the effects of an adjacent development.

Construction Administration/Observation:

  • On-site personnel focused on observing construction methods and installation.
  • Administration of payment applications, disbursements, change orders, and punch lists.
  • Interpretation of plans for contractor and/or client during construction.

“I wanted to pass along Council’s “thank you” for the quick response, hard work, and most importantly finding a contractor close to the budget numbers for this project.”

State Route 47 Safety Improvements*

Sidney, Ohio

Choice One Engineering designed improvements along State Route 47 (W. Michigan Street) from Wal-Mart’s west driveway to Wayfarer/Folkerth intersection, which is approximately 2,600 feet. Choice One also collected traffic volumes, crash data, and completed capacity analyses to help determine the appropriate improvement to improve the safety and efficiency of the corridor keeping all modes of transportation in mind.
