We collect a broad spectrum of traffic data – intersection turning movement counts, queuing delay, vehicle gap data, vehicle volume/speed/classification, etc. The type of traffic data analysis we perform is largely driven by the project objectives and the agency performance standards. Examples of performance measures we used in previous projects include peak hour factor, benefit-cost ratio, traffic volume/speed, travel delays, vehicles hour traveled (VHT), vehicle miles traveled (VMT), and so on.
Improve traffic mobility, road safety and system efficiency.
We are a diverse, dedicated and experienced group of engineers with sound practice and understanding of the current engineering standards and policies. We specialize in transportation planning and traffic engineering with the goal of providing strategic, effective and innovative solutions to current transportation challenges.
Our team is flexible and able to adapt our solutions to each client's unique needs. Our engineers are experienced in the use of a wide range of software applications, including but not limited to Highway Capacity Software (HCS), Synchro and Sim Traffic for intersection analysis, ArcGIS packages for geographic mapping, MnESAL for traffic trend analysis, TransCAD for travel demand modeling, FREEVAL for freeway traffic simulation, and DynusT for mesoscopic traffic simulation.
These studies often involve assessing the current conditions and potential impact of a proposed development on the connected transportation system, and recommending improvements necessary to maintain a satisfactory level of service and safety. This process serves as a "bridge" between the regional planning process and the detailed project design and engineering phases.
These studies include intersection alternatives analysis, assessment of safety and capacity, parking studies, bicycle/pedestrian route planning, NEPA environmental documents, environmental assessment, and development of project cost estimates.
Our custom GIS maps are individually focused on your project needs. Our mapping service includes, but are not limited to, road informatics, demographic analysis, utility mapping, and data services.
Transportation research can take many different forms, but we generally follow a standard approach: analyze the existing methodologies, conduct an extensive literature review, propose a solution validated by data, and finally report the research findings.
There are different traffic forecasting methods we apply for different types of studies.
- Statistical trend analysis is typically conducted for base-year and design-year annual average daily traffic (AADT), base-year and design-year heavy commercial annual average daily traffic (HCAADT), design hour volumes (DHV) with associated directional distribution (DD), 20-year and 35-year cumulative Equivalent Single Axle Loads (ESALs).
- For more comprehensive corridor analysis, travel demand models (TDM) such as TransCAD and CUBE Voyager populate future traffic assignment, which gives regional traffic patterns.
We start by identifying construction needs such as rehabilitation, reconstruction, capacity expansion, or work zone staging. The next step is to finalize the design concept and study the potential traffic impact for each design alternative. This usually requires model simulations to analyze traffic impact and traffic flow patterns as well as the associated road user cost for each modeled scenario. Critical intersections are analyzed using intersection simulation software such as Synchro/SimTraffic or HCS for vehicle delays and level of service. For corridor or regional level traffic analysis, several tools may be used depending on the network size and the level of regional impact, such as DynusT/DynaStudio and FREEVAL.
Work zone impacts are better managed by actively monitoring and managing the impacts during the course of the project implementation. The performance monitoring allows us to measure the work zone impacts, determine whether the impacts meet the desired level of safety and mobility performance for that work zone, and also evaluate how well the transportation management plan (TMP) performs. Our periodic reporting enables the timely communication among the stakeholders and assists the decision-making process during construction.
