SUPPORTING DATA SUMMARY

When transportation control measures of any type are to be imposed, the plans shall contain a summary of the data, computations, and rationale used to develop the transportation control measures that will result in the required reduction of emissions. Such a summary shall, as a minimum, contain the material described below. Suggested procedures for obtaining and coding information about air pollutant emissions from stationary and mobile sources have been published. The detailed computations and data shall be retained by the State agency and made available for inspection by the Administrator at his request.

1. The transportation control plan shall display total emissions of hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx), subdivided into emissions from mobile and stationary sources, that will occur with and without implementation of the transportation control measures in each region or subregion and time period in which a proportional or other air quality model is used to determine air quality. These data shall be projected for at least 5 years in 1-year intervals starting with the year in which the national ambient air quality standards are to be achieved. The data shall be displayed in a format similar to table 1.

2. If the transportation control measures, either in their application or their effect,

distinguish between trip types or vehicle types, the transportation control plan shall display vehicle miles traveled and emissions of HC, CO, and NOx due to each trip type or vehicle type that will occur with and without implementation of the transportation control measures in each region or subregion and time period in which a proportional or other air quality model is used to determine air quality levels. A stategy that results in different percent emissions reductions of HC, CO, or NOx for different trip or vehicle types should distinguish between trip or vehicle types in its effect. The data shall be displayed in a format similar to table 2.

3. If the transportation control measures include traffic flow measures, the transportation control plan shall display average speeds and vehicle miles traveled according to roadway type (freeway, arterial, local/ collector) that will occur with and without implementation of the transportation control measures in each region or subregion and time period in which proportional or other air quality model is used to determine air quality levels. The plan shall also display emissions of HC, CO, and NOx from mobile sources, subdivided according to roadway type, that will occur with and without implementation of the transportation con

trol measures in each region or subregion and time period in which a proportional or other air quality model is used to determine air quality. The data shall be displayed in a format similar to table 2.

4. If the effectiveness of the transportation control measures depends in whole or in part on voluntary public response to changes in prices or taxes, mass transit improvements, or other incentives or disincentives affecting vehicle emissions, travel frequency, mode, location, time of day, or other characteristics of travel demand, the transportation control plan shall display the demand elasticities or other appropriate quantitative measures of public response to such incentives or disincentives that were used to evaluate the effects on emissions of the incentives or disincentives. The sources of these elasticities or other quantitative measures shall be described.

5. The sources of all traffic data, such as vehicle miles traveled and speeds by trip type, vehicle type, and roadway type, used in evaluating the effects upon air quality of the transportation control measures shall be described in the transportation control plan.

6. The assumptions, judgments, and computations used to develop the information in items 1 through 4 above shall be summarized in the transportation control plan.

A transportation control plan that fails to include any element of data required by this appendix will be acceptable only if the plan presents the data and analytic procedures used to estimate the effects on air quality of the selected transportation control measures and provides adequate justification for the use of such data and procedures.
