Survey Population EstimateSurvey Population Estimate
Survey population estimate is based on vehicle count Survey population estimate is based on vehicle count datadata
Vehicle count data adjusted for estimates of turnover Vehicle count data adjusted for estimates of turnover rates rates
Different turnover rates for different types of sitesDifferent turnover rates for different types of sites 1 = No or Low Turnover1 = No or Low Turnover
2 = Moderate Turnover2 = Moderate Turnover
4 = High Turnover4 = High Turnover
Estimated total survey population for holidays, Estimated total survey population for holidays, weekdays, and weekend days based upon adjusted weekdays, and weekend days based upon adjusted vehicle counts and 2.8 people per vehiclevehicle counts and 2.8 people per vehicle

Sampling DesignSampling Design
Based on the survey population, calculated required Based on the survey population, calculated required number of samples to achieve a statistically valid sample number of samples to achieve a statistically valid sample size (± 10%) for individual sitessize (± 10%) for individual sites
Determined number of survey days based on:Determined number of survey days based on: The number of required samples The number of required samples

Proposed Sampling ApproachProposed Sampling Approach
Proposed survey locations are organized based on use Proposed survey locations are organized based on use levels:levels: Individual sites proposed for statistical surveys – use is high Individual sites proposed for statistical surveys – use is high
enough to support statistically valid survey effortenough to support statistically valid survey effort
Grouped sites proposed for statistical surveys – when individual Grouped sites proposed for statistical surveys – when individual sites are combined, use is high enough to support statistically sites are combined, use is high enough to support statistically valid survey effortvalid survey effort
Grouped sites proposed for qualitative surveys - when individual Grouped sites proposed for qualitative surveys - when individual sites are combined, use is high enough to warrant qualitative sites are combined, use is high enough to warrant qualitative survey effortsurvey effort
Sites not proposed for survey – surveys are not feasible or Sites not proposed for survey – surveys are not feasible or practical due to very low use levelspractical due to very low use levels

General ProtocolsGeneral Protocols
Statistical sites will be sampled on weekdays, weekend Statistical sites will be sampled on weekdays, weekend days and holidaysdays and holidays
Qualitative sites will be sampled on weekends and holidaysQualitative sites will be sampled on weekends and holidays
Sampling effort for Statistical sites is stratified by month Sampling effort for Statistical sites is stratified by month based on use distribution – June, July, Augustbased on use distribution – June, July, August For each month, the number of holiday, weekend-day, and For each month, the number of holiday, weekend-day, and
weekday sample-day are assignedweekday sample-day are assigned
Surveys will not be conducted on FridaySurveys will not be conducted on Friday
Each sample-day represents two sample-blocksEach sample-day represents two sample-blocks
Each sample-block represents a four hour sample effortEach sample-block represents a four hour sample effort
