Index of Strategies by Implementation Timeframe and Relative Cost

Exhibit IV-1 provides a classification of strategies according to the expected timeframe and relative cost for this emphasis area.

EXHIBIT IV-1
Classification of Strategies According to Expected Timeframe and Relative Cost

		Relative Cost to Implement and Operate
Timeframe for Implementation	Strategy	Low	Moderate	Moderate to High	High
Short (< 1 year)	4.1 A1— Target enforcement	XXX
	4.1 A2—Conduct educational and public information campaigns		XXX
Medium	4.1 B1—Change or mitigate the effects (1–2 years) of identified elements in the environment a			XXX
	4.1 B2—Reduce nonrecurring delays and provide better information about these delays b			XXX
	4.1 A3—Educate and impose sanctions against repeat offenders	XXX
Long (> 2 years)

^a There are a number of actions that may be taken under this strategy. The degree of reconstruction required is normally assumed to be relatively small. There will be cases, however, where more costly investment in reconstruction will be necessary, even involving additional right-of-way, and thus requiring a longer timeframe, as well.
^b There are a number of actions that may be taken under this strategy. The classification of this strategy is based upon the assumption that the agency is seeking those that avoid major investments, such as new right-of-way, or major reconstruction.

In several cases, the implementation time will depend upon such factors as

• Agency procedures,
• Scope of the proposed program,
• Level of reconstruction required,
• Number of stakeholders involved, and
• Presence of any controversial situations.

The range of costs may also be somewhat variable for some of these strategies because of many of the same factors. Placement in the table above is meant to reflect costs relative to the other strategies listed for this emphasis area only. The estimated level of cost is (1) for the commonly expected application of the strategy or (2) in accordance with the additional specific assumptions recorded in the footnotes.

Note: Strategies involving changes to external elements and to reducing delays range from very low cost and short range (e.g., restriping turn lanes) to relatively high cost and longer range (e.g., centrally controlling a set of traffic signals now under individual controllers). A midpoint in that range has been used in the table.
