13. Time-of-Day Analysis can be conducted using Daily and Time- of-Day Model The benefits for each analysis time period calculated separately and summed to produce the total For peak period models, modules are applied to each period module and the benefits are summed. For daily models, period-specific multiplication factors utilized to convert the daily link volume to analysis period volumes default factors derived on data from Broward County state roads.

14. Performance Measures Vehicle miles of travel (VMT); Vehicle hours of travel (VHT); Average speed; Number of accidents Fatality Injury Property damage only Fuel Consumption (gallons) Monetary benefits to users and/or agency, as appropriate Emission (gm) Hydrocarbon Carbon monoxide Oxides of Nitrogen

15. Benefit Evaluation Methods A method developed for each component Review and assessment of methods used in evaluation tools Review of literature Default ITS impact parameters derived based on a review of previous evaluation studies, USDOT benefit database and the values used in existing ITS sketch planning tools. The user will be able to change the default ITS impact parameters and perform sensitivity analysis.

16. ITS Cost The cost information include the number and types of equipment required for each type of evaluated ITS deployment The cost information include initial cost, operation and maintenance cost, estimated interest rate, and life time of each equipment Based on information from ITS agencies collected in a previous FDOT effort and information collected in this study User can change the defaults and is encouraged to do this based on projects at hand

17. Dollar Values Travel Time value is 13.45 dollars per person-hour. For commercial vehicles $71.0 per hour based on TTI study. $3,200,000 per fatal crash, $74,730 per injury crash, and $3,000 per PDO crash Fuel Consumption $3 per Gallon Emission using IDAS defaults -  $1,774, $3,731, and $3,889 per gallon, for the HC, NOx, and CO pollutants.

18. Air Pollution Dollar Values IDAS does not mention the source of the dollar values Pollution impacts human health and causes ecological and esthetic degradations Review indicates that IDAS values could be conservative estimates. Thus, they were used in this study.

19. ITS impact parameters Default ITS impact parameters derived based on a review of previous evaluation studies, US DOT JPO benefit database and the values used in existing ITS sketch planning tools. The user will be able to change the default ITS impact parameters and do sensitivity analysis.
