Chapter 11: Feasibility/Route/Corridor Studies
Section 1: Overview
Purpose of Feasibility/Route/Corridor Studies
TPP uses three types of studies to identify transportation
needs while determining critical elements of engineering and the
economic feasibility of a proposed facility/route/corridor. Such
studies establish design concepts, general right-of-way requirements
and associated project impacts. Various elements associated with
a study can include studying various alternatives, analyzing current and
future traffic, analyzing potential environmental problems, development
of cost estimates and determining feasibility.
Laws and Regulations Regarding Feasibility/Route/Corridor Studies
The studies comply with all applicable federal and state laws,
and codes. There are no federal or state laws or regulations specific
to feasibility/route/corridor studies.
Request for a Feasibility/Route/Corridor Study
Projects may be suggested by maintenance supervisors, area
office staff, district staff, local transportation partners, developers,
or the society served.
For urban projects, particularly capacity improvements, the
need for a project may be determined from traffic modeling of future
growth and travel demands. This data may be requested from the TPP
Traffic Analysis office or, in some cases, from local government
transportation planners. The project should be evaluated for consistency
with the approved MPO planning documents.
For some urban projects, the development process may encompass
a need for a sustainable street and transit network associated with
the potential project in the context of desired land uses and urban
design established in regional plans, comprehensive plans, neighborhood
plans, other local plans, special district plans, relevant public-private
partnerships or economic development plans.
Rural multimodal mobility, safety, and added capacity projects
may be identified through local decision makers and stakeholders.
Trend analysis and forecasted growth data may be obtained from TPP
Traffic Analysis office.
Area Engineers generally determine rehabilitation needs for
their areas in consultation with maintenance supervisors and local
officials.
Off system projects are generally identified through statewide
ranking formulas and through consultation with local officials.
Public meetings may generate comments on area wide transportation
needs.
A review of traffic crash information may alert the department
to needed improvements.
Needs may be identified through the Pavement Management Information
System (PMIS) or the Wet Weather Accident Reduction Program (WWARP).
Studies from adjacent projects may indicate needs in other
areas.
