Title 23 of the United States Code (USC) & 134 states that it is in the national interest to encourage and promote the safe and efficient management, operation, and development of surface transportation systems that will serve the mobility needs of people and freight and foster economic growth and development within and through urbanized areas, while minimizing transportation related fuel consumption and air pollution. To accomplish all these objectives, the Metropolitan Planning Organizations (MPO), in cooperation with the State and public transit operators, are required to develop transportation plans and programs for urbanized areas of the State.
The plans and programs for each metropolitan area are required to provide for the development and integrated management and operation of transportation systems and facilities (including pedestrian walkways and bicycle transportation facilities) that will function as an intermodal transportation system for the metropolitan area and as an integral part of an intermodal transportation system for the State and the country.

ITS Architecture for the SNHPC Region
Regional Transportation PlanIn keeping with the provisions of the Title 23 of USC, SNHPC prepares a Regional Transportation Plan (RTP) that provides for consideration of all modes of transportation, including highway, transit, rail, bicycle and pedestrian walkways, freight, and air travel. The plan is continuing, cooperative, and comprehensive, commonly referred to as “3C” process.
I-93 Widening
I-93 is a major transportation corridor for New Hampshire, both for commuters and visitors to the state, linking the greater Boston area with tourism related activities in the northern and central parts of the state. It serves as a vital link to the regional economic activities. Currently, the corridor is a 4-lane (2 lanes in each direction) interstate facility. The capacity of the highway to carry traffic has long been exceeded, due to the high growth the region has experienced. To address these capacity problems, the New Hampshire Department of Transportation is expanding the highway to 8 lanes (4 lanes in each direction). The SNHPC is currently participating in the Community Technical Assistance Program (CTAP), which is being developed through the State of New Hampshire’s Office of Energy and Planning. CTAP is designed to help communities in the I-93 region plan for future growth.

Local Trip Generation Rates
As part of its Unified Planning Work Program (UPWP), the Commission continued work on the trip generation study for various land use types in the Southern New Hampshire region. Transportation professionals commonly use the ITE Trip Generation Manual to establish trip rates by land use. These rates are national averages and may vary from area to area. In some cases, land use types are represented by trip rates based on only a few samples. In other cases, some land use types are not represented at all. The shortcomings of the ITE trip manual are evident in the wide range of rates it provides for land use types. The SNHPC’s report supplements the ITE trip data with local data that has been collected at similar sites. As a result, the local trip generation study performed for the Southern New Hampshire area (and specifically for the SNHPC region) by the SNHPC provides a more complete and accurate picture of trip rates for the region.
The basic purpose of this study is to determine local trip generation rates for individual land use types in the Southern New Hampshire Region for which the data in the ITE trip generation report is lacking.

Traffic Counting Program
As part of the Unified Planning Work Program, the Commission conducts traffic counts on regional roadways on an annual basis. A total of approximately 500 locations are counted each year, with about 30 to 35 percent of the counts done at the request of the New Hampshire Department of Transportation and the remainder is done as per the Commission’s own requirements. If you are a member community and would like to request a traffic count, please contact the Commission for your request to be included in that year’s count list. For a historical traffic count database, please check our Traffic Volume data section.
