JMT’s multi-disciplined approach to transportation planning begins with engineers, planners, GIS analysts, landscape architects, environmental specialists, public involvement professionals, and graphic artists who are committed to providing our clients with transportation solutions that meet the travel demands of the location and support the long-term community vision. We work closely with area stakeholders and community members to ensure all aspects of the solution have been coordinated through the public involvement process.
JMT has extensive experience in completing multi-modal transportation projects from the beginning, identifying the purpose and need, alternate development and evaluation, through the NEPA process and documentation. We incorporate a public involvement process throughout the transportation planning process to ensuring an informed community. JMT continues to think “outside the box,” presenting new alternatives and options that utilize cutting-edge designs and technologies that can be carried forward into full design and are permittable and constructible.
Projects within transportation planning include: evaluating highways, local streets, corridors, and intersections/interchanges; transit modes, alignments, and stations; pedestrian and bicycle facilities; understanding the natural, social and economic environment; ADA compliance; Complete Streets and ensuring Context Sensitive solutions are found.
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 factor into environmental analysis.
JMT has performed travel demand forecasting for nearly three decades 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 using 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. Studies and reviews completed by JMT include:
- Traffic signal warrant studies
- Phasing studies
- Signal timing studies
- Crash analysis
- Origin-destination studies
- Truck studies
- Pedestrian studies
- Delay and queuing studies
- Bicycle studies
- Traffic calming
- Roundabout studies
- Road safety audits
- Corridor studies
- Traffic impact study reviews
- Transit studies
- School studies
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.
