Traffic engineering encompasses many elements including data collection, studies and analysis, forecasting, and design of traffic control features and intelligent transportation systems. Traffic engineering is a skilled discipline requiring knowledge of Federal, state, and local criteria, as well as an understanding of the human factors that remain crucial elements of transportation projects.    

JMT meets the needs of our many clients by designing efficient solutions to resolve their transportation traffic engineering issues. Through our working relationships with many transportation agencies, we understand the similarities and differences between jurisdictions. This assists us in providing the safest and most cost-effective designs to each client.  

At JMT we have a staff of professionals that have performed studies and designed projects throughout the eastern U.S. for Federal, state, and local governments, and private clients. We understand how to incorporate human factors into our designs to assist motorists in making informed and safe decisions on the roadway. Sustainable solutions are our specialty and are integral in all we do.

Travel Demand Forecasting

The development of travel demand forecasts is a vital step in evaluating the future needs and demands of a transportation facility, such as the number of lanes, lane configurations, type of interchange, and potential for multimodal facilities and connections. Travel demand forecasts can help in the early identification of major cost implications and also factor into environmental analysis. 

JMT has performed travel demand forecasting for more than 25 years through both regional travel demand models and the manual four step process. We have developed a regional forecasting model for a four-county area. Other forecasting assignments include transportation plans, individual project forecasts for corridors involving transit, express toll and HOV lanes, and for environmental assessments including air and noise analysis. Our modelers use software such as CUBE and TP+. JMT understands the modeling process, and our staff possesses the ability to present the information in a manner that helps our clients to make informed decisions.

Traffic Studies & Analysis

JMT conducts a wide variety of traffic studies, leading to safer roadways and improved traffic and transit operations. Crash studies assist in reducing the potential for collisions and provide a safer environment for pedestrians and bicyclists. Operations studies are conducted to improve travel in a corridor or area, often through the use of modeling tools. 

JMT analyzes existing and projected traffic volumes to determine the adequacy of existing operations and to evaluate if proposed improvements would resolve deficiencies. Various analysis packages, including VISSIM, CORSIM, SIDRA/Intersection, SYNCHRO, and Highway Capacity Manual Software, are utilized in the analysis and can range from signal timing to evaluating future improvements. Travel time studies are performed to validate the models using GPS equipment.  

The traffic studies performed by JMT account for many different elements to ensure that the needs of the client are met.

Traffic Data Collection

Traffic data collection provides the base information required for many aspects of transportation projects. These include planning and design studies, traffic analysis studies, corridor studies, signal timing studies, parking studies, pedestrian and bicycle studies and trip generation studies. 

At JMT, we collect traffic data through various methods, including manual and video methodology for turning movement counts at intersections, and through portable counts at various other locations. Typical count types include volume, classification, speed, as well as vehicle occupancy data. JMT has an experienced staff of personnel who are familiar with methods of obtaining the traffic data that our clients need. This allows us to assess each project and determine what information should be gathered, and how, to meet the study objectives. JMT has a strong adherence to quality control to ensure that the traffic count data is accurate.
