2017 Adjusted Count Report February 12, 2018

Transcription

1 A statewide multi-use trail user study and volunteer data collection program 2017 Adjusted Count Report February 12, 2018 The following report includes the final adjusted infrared (IR) counter data at 15 count locations for the full 2017 calendar year from Sunday, January 1st, 2017 through Sunday, December 31st, Not all trails have complete data for the entire year. The counters in Middlebury, and Hamden were added after the beginning of Counters in New, and New Haven experienced periods of no data due to insects nesting in the IR sensor. The counter in experienced sensor malfunction at the end of the year. Two days of data in were also impacted by a counter malfunction. Missing data is indicated with an in the data sheets. In an attempt to account for missing data, estimated annual totals were calculated by multiplying the average daily use on each trail (for days with data) by 365. All other calculations are based on the adjusted counts Adjusted Totals Understanding the Data This count data shows number of uses or trips, not visits or visitors. Infrared counters register warm bodies passing by the IR scope. Trail users who travel out and back on the same route will pass the counter twice and be counted twice. For trails with primarily out and back traffic, trail visits can be estimated at ½ of the count total. The raw data was adjusted or calibrated using manual counts completed by volunteers. Manual count totals that volunteers recorded were compared to the figure registered by the IR counter for that hour. Individual adjustment factors were established by dividing the manual count total by the IR count total for identical time periods. These factors ranged from 1.29 to These factors are consistent with factors calculated for other multi-use trails in similar studies. For trails that did not submit manual count forms, the lowest calibration factor (1.29) was applied. The manual counts showed that the IR counters consistently undercount. Undercounts are typically due to people travelling side by side or bikes travelling too fast. Manual counts are important to ensure the correction factors applied to each trail are appropriate and reflect the performance of the individual IR counters. *indicates estimated annual total based on daily average A total of 1,281,051 uses or trips were recorded across all 15 sites. Using average daily counts to account for missing data, the 15 trails had more than an estimated 1.4 million uses in The most heavily used trails during 2017 were the Greenway in Derby, The in, and the Hop River Trail in Vernon. Counters on the Air Line Trail in Thompson and the Larkin State Bridle Trail in recorded the lowest use volumes.

2 Understanding the Tables Pages 1-7 of the attached report detail the adjusted daily totals for each trail. All figures were adjusted using the factors explained above. s and holidays are shaded grey and blue, respectively. Since weather plays a major role in outdoor activities, the table includes daily weather data reported at Bradley International Airport in Windsor Locks. The weather data was downloaded from the National Center for Environmental Information at the National Oceanic and Atmospheric Administration (NOAA) The weather data includes daily high and low temperature, precipitation, snowfall, and snow cover. Data from Bradley Airport was used because it was the most complete dataset available, and it was the only dataset in the state to include snow depth. The data has been conditionally formatted and shaded to to help visually interpret trends. Some things to look for: plays a major role in trail use. Trail use lags on very cold days. See March 12th. Trail use lags on days with heavy precipitation. Look at May 5th or June 19th. Trail use spikes on days in the winter and early spring when temperatures rise, especially on weekends. For instance, see trail use on April 2nd and 9th. While people still use snow covered trails, those where snow is removed saw more rapid rebounds in uses following major snowfall. There was a major snow event on March 15th that drastically impacted trail use across all trails, but trail uses in Derby and, where the trail is plowed, rebounded more quickly. Use on trails that have more commuter use and less recreational use, like the FCHT New Haven or CTfastrak Trail in New, may be less impacted by weather. Monthly Summary The adjusted monthly totals tables break down the trail use totals by Month. The table at the top of the page details the adjusted count totals by site by month. Cells shaded orange indicate months that count totals were impacted by missing data. The lower table shows the percent of total annual counts by month. Be aware that the percent of total for months with missing data reflect that fact. The cells have been formatted so that cells with higher values are shaded darker red. Both tables show totals for all trails to the right. Some things to look for: The heaviest use occured between the months of April and October when approximately 76% of trail uses across all sites were recorded. Use on trails that have more commuter use and less recreational use, like the FCHT New Haven or CTfastrak Trail in New, may have more evenly distributed uses over the year. Day of Week Summary The Adjusted Day of Week Summary page breaks down the annual adjusted counts by day of week. Three tables are presented. The first table details total counts by the day of week. The second table shows the calculated daily average by day of week. The third table shows the percent of trail use by day of week for each trail, and is formatted with higher values shaded darker red. All three tables show the totals for all trails to the right. Some things to look for: Generally, heavier use occurred on the weekends than during the week. Trails with primarily recreational use tended to have a more pronounced weekend/ weekday discrepancy. Use on trails that have more commuter use and less recreational use, like the FCHT New Haven or CTfastrak Trail in New, may have more evenly distributed uses by day of week, and may even have heavier use during the week.

3 The Adjusted Hourly Summary breaks down trail use by hour of day. The top table shows average hourly totals for each site, as well as the average hourly total for all sites. The bottom table shows percent of use by hour of day of the total daily average use for each trail and for all trails combined. The second table is formatted so that cells with higher values are shaded darker red. Some things so look for: Most trail use (96.6%) took place between 6am and 7pm. FCHT New Haven and CTfastrak Trail in New had more uses later at night than other trails, perhaps due to heavier commuter use.

Total Total 1,281,051 *1,401,415 All figures are counts or trips, not visitors. For most trails with visitors passing a counter twice per visit, a good estimate of visits is 1/2 of the count total. All counts were adjusted to account for inherent undercounts typical of IR Counters. Adjustment factors were applied based on comparisons between the IR counts and manual counts.
