ITS planning is to integrate ITS into the transportation planning process.
Transportation planning helps in shaping a well balanced transportation system
that can meet future demands.
Transportation planning is an iterative process which include problem
identification, solution generation, analysis, evaluation and implementation.
This can be integrated with ITS using computers, communication systems and
software.
As planning is normally made for long period, installing ITS facilities needs to
be updated and one should ensure that the equipments and technologies are
compatible for future improvement and expansion.
The steps in traditional transportation planning are as follows:
- Establish goals and objectives
- Inventory existing conditions
- Analyze existing conditions
- Long range/ short range element
- Forecast land use, population/employment
- Forecast future travel/trips
- Develop and evaluate alternative transportation plans
- Prepare recommended plans and programs
ITS transportation planning process differs from the traditional transportation
planning process.
ITS has the unique capability to integrate different modes of transportation
such as public auto, transit, and infra-structural elements through
communications and control.
The multi-modal integration potential provides a great opportunity for planning
across modes.
The comparison between ITS approach and conventional approach for solving
various transportation problems are shown for few problems are shown in
table. 1.
