Planning and ITS architecture

ITS architecture is a useful tool for integrating ITS technique into planning process. The ITS architecture defines the comprehensive set of data that should be shared by various agencies of transportation network. With the knowledge of what data must be exchanged, these agencies develop a common interest in cooperating planning efforts between all transportation projects.

Planning for ITS

ITS planning process follows a systems engineering approach to develop a deployment plan in descending order vision, goal, objectives, and functions. Table. 1 shows the ITS approach for achieving goal ``enhance public safety''.

Table 1: ITS approach for the goal enhance public safety

Vision	Improvement of travelers safety by providing advance warning by
	implementing crash counter measures and by controlling to the security
	of the transportation facilities
Goal	Enhance public safety
Objectives	Promote safety of transportation	Reduce crashes on freeways
	facility	and streets
Functions	# Monitoring of rest areas	# Implement crash counter
		measures at high accident
	# Provide public safety at park	locations
	and ride lots
		# Implement work zone safety
	# Coordinate emergency response	measures
	using appropriate agency
		# Install traffic signs signals and
		road marking
		# Remove obstruction from the
		incident scene

Integrating ITS into Transportation planning

Integrating ITS into transportation planning process require overcoming some obstacles and some changes in the business practices of many institutions. The major challenges in mainstreaming ITS into everyday operations of transportation agencies are:

• Institutional coordination and cooperation for sharing information and data
• Technical compatibility among ITS projects
• Human resource needs and training
• Financial constraints and opportunities to involve the private sector

Most public agencies are aware of the challenges in mainstreaming ITS into transportation planning process where ITS projects are part of traditional transportation programs on local or state level to achieve the best output from transportation investments.
