Transportation Planning Services

Transportation and mobility issues represent some of the most chronic challenges many communities face.  NRPC, as the transportation planning body for the region, is uniquely positioned to help communities address transportation needs in a collaborative manner to minimize long-term costs and improve overall transportation functionality.


Traffic Data Collection
Access to objective and accurate traffic data is necessary to justify road infrastructure investments. NRPC’s database of current and historical traffic counts also helps decision-makers respond to constituent concerns, analyze traffic trends and efficiently manage resources for road projects.  This service is available to communities at the request of local elected officials.  NRPC can provide 24 hour traffic volumes, speed data and vehicle classification data.  In addition, NRPC can provide turning movement count data for intersection analysis and signal warrant analysis.


Traffic Demand Model

NRPC’s Travel Demand Forecasting Model can predict vehicular traffic under an endless number of planning scenarios such as impacts from planned development or other changes to the road network.  The model uses the latest socio-economic and land use data and undergoes extensive calibration to produce predictions with a high degree of confidence, which makes it well-suited to support traffic planning on local, corridor, and regional-scales.


Intersection Analysis

Poorly-timed traffic signals and chronically-blocked intersections can trigger congestion, generate safety problems, and discourage commercial activity, all of which can propagate through the surrounding transportation network.  Using the latest in traffic micro-simulation software, NRPC can quantify intersection operation and performance and formulate appropriate recommendations for improvements.


Corridor Studies

Instead of focusing on traffic problems at individual intersections, a corridor study provides an opportunity to evaluate roadways in a holistic and integrated manner, providing solutions to chronic and systemic issues like congestion and safety concerns.  NRPC can provide corridor level traffic and land use analysis to assess performance, safety, aesthetics and impacts of future development and help identify gaps in existing infrastructure including pedestrian and bicycle facilities.  NRPC staff will work with local officials to identify key issues and concerns, invite full public participation, and analyze a vast warehouse of traffic, land use and demographic data before making recommendations.


Road Surface Management Studies

In order to most efficiently manage municipal highway funds it is important to maintain roadways before conditions deteriorate to the point that roads need to be entirely rebuilt.  Road Surface Management Studies (RSMS) provide decision-makers an objective and impartial inventory of existing roadway conditions and a prioritization of maintenance needs to help communities best leverage their existing maintenance resources.  Through a repair strategy and a 10-year budget projection which accounts for pavement deterioration over time, an RSMS can help justify maintenance budget increases and ensure that existing funds are best leveraged to address existing needs.


Parking Studies

To ensure municipal parking resources are being utilized efficiently and effectively, NRPC works with communities to collect and analyze parking pattern data.  Parking studies provide an impartial and objective mechanism to identify inefficiencies as well as potential strategies to maximize returns on parking investments.  Parking infrastructure that is over-utilized can discourage commercial traffic while under-utilized lots can be a drain on municipal maintenance budgets.  Parking studies can help identify cost-effective solutions to common parking problems and provide baseline data regarding where it might be feasible to repurpose existing parking facilities.


Road Safety Audits

A road safety audit is the formal safety performance examination of an existing or future road or intersection by an independent, multidisciplinary team. It qualitatively estimates and reports on potential road safety issues and identifies opportunities for improvements in safety for all road users.  A road safety audit is often a prerequisite to qualify for state funding for roadway safety improvements.
