The following are common types of services we perform. Please do not hesitate to contact us with any questions you may have.
Traffic Impact Analyses/Assessments
We’ve completed Traffic Impact Analyses (TIA) and Assessments for hundreds of projects including schools, single family/multi-family residential developments, retail/commercial projects and more. The main goal for these types of studies is to analyze the existing roadway conditions and forecast newly generated project traffic. Tasks includes the review of general roadway information on the adjacent street system, baseline vehicular volumes, and entering sight distance data. Forecasts of future traffic and dispersion patterns on the street system are then determined using established trip generation and distribution techniques. As a final step, appropriate conclusions and mitigation measures are defined.
Trip Generation Assessments
Depending on the scale and type of your project (redevelopment of an existing structure, smaller-scale project, etc.), some jurisdictions may not require a full TIA. In these cases, you may be liable to produce a trip generation assessment. Trip generation is used to determine the magnitude of project impacts on the surrounding street system. This is usually denoted by the quantity or specific number of new trips that enter and exit a project during a designated time period, such as a specific peak hour (AM or PM) or an entire day. We can provided you with an estimated trip generation assessment based on the proposed land use(s) of your development in accordance with the most recent Institute of Transportation Engineering (ITE) data.
Traffic Data Gathering
Equipped with our own camera technology, we can perform peak time frame / 24 hour counts to determine baseline traffic conditions at intersections and along roadways adjacent your subject site. Please don’t hesitate to contact us with your traffic data needs.
Safety Analysis
Many jurisdictions require that various traffic safety conditions be analyzed before a subject site is approved for construction. Examples of traffic safety analyses include:
Sight Distance Access Analysis: our firm can review your project’s access configuration and let you know if it conforms to jurisdictional safety standards
Vehicle/Truck Turning Movement Analysis: to ensure the safe maneuverability of your access(es) and internal roadway network, we can perform modeling (AutoTurn technology) to ascertain whether your subject site provides vehicles with the proper space needed to navigate your site (see diagram below)
Accident History Reports: determine if any traffic accidents have occurred adjacent your proposed development to identify possible safety concerns/trends on the surrounding roadways
Left/Right-Turn Warrant Analyses: assess left/right-turn storage needs at your project’s access to ascertain if additional roadway channelization is necessary
Traffic Control Plans/Traffic Management Plans
Will your project entail work/construction within public right-of-way (ROW)? Many jurisdictions will require that you submit a traffic control plan (TCP) and receive proper permitting before getting your project underway/closing off ROW. We can provide you with a professional plan that will meet MUTCD and jurisdictional requirements. Examples for situations that may require a TCP include:
Land/Road Closure for Construction
Community Event/Block Party/Street Fair/Parades
Utility Work
Queuing Demand Analysis
Does your project contain a drive-through? Depending on your site layout and anticipated trip generation, you may need a queuing analysis performed. Projects that may necessitate this type of a study include: coffee stands, car washes, school, fast food establishments and more.
Parking Demand Analysis/Assessments
Need to substantiate the parking demands for a proposed development? By utilizing the latest data from the ITE (Institute of Transportation Engineers) Parking Generation Manual, we can provide you with an assessment that forecasts the parking demands required for a multitude of land uses.
