1 Bicycle Count Data December 28 Published By: San Luis Obispo Public Works Department 919 Palm Street, San Luis Obispo, California 9341 Telephone (85) ; FAX (85)

2 Introduction The City s General Plan Circulation Element encourages San Luis Obispo residents to reduce their use of private motor vehicles and increase their use of bicycles, carpools, buses, and walking. The City has instituted a variety of programs to promote this shift in transportation modes. To determine the effect of these programs, the use of various transportation types is monitored every two years. This report presents one component of the monitoring program. Beginning in 1996, the City of San Luis Obispo instituted a program to count bicycle traffic at various street intersections throughout the community. This initial study involved 14 stations across the city, and counted a total of 1,452 bicyclists. This work has been continued every two years since, and is made possible by the voluntary efforts of students from the Civil and Environmental Engineering Department at Cal Poly State University, San Luis Obispo and from members of the City s Bicycle Advisory Committee. Bicycle counts are taken in the middle of the week and collected at fifteen minute intervals for two hours in the afternoon during the month of October. This time is chosen because the goal of the counts is to measure the amount of bicycle commuters, as well as recreational riders. Bicycle commuters represent a daily shift in automobile vehicle use, and utilize bicycling facilities on a regular basis. However, this time period is only a small snapshot of overall bicycle usage throughout the City. Since Cal Poly University is a popular bicycling destination, all streets entering the campus are counted. At other stations, at least one leg of the intersection is part of the City s official bikeway network (The official bikeway network is identified in the San Luis Obispo s Bicycle Transportation Plan). For analysis purposes, these two types of stations are compared further in the report. See Figure 8 on page 11 for a map of locations where counts were performed. Location summaries for each station are included at the end of this report. It is important to note that these counts are subject to substantial variation from year to year. This data can be considered a snapshot of the total ridership of the City. There may be factors such as weather conditions, road conditions, gas prices, and localized special events that can influence the volume of bicycle traffic on any given day at a particular count station, or throughout the City. For each count year, these statistics are recorded so that comparisons may be made between each year. Several charts show these comparisons. In 28, the City began to collect data regarding helmet usage and sidewalk usage at each bicycle station. This data is included in the report as a baseline measure for future counts.

No trains were parked on the train tracks during the times the counts were performed. Cal Poly Parking fees (28) o $1.5 per hour for metered parking, $5. per day general pass, and $11 per quarter (11 weeks) general permit. On October 7, the average price of gas in San Luis Obispo was $3.53/gallon. o California average for regular unleaded was $3.6/gallon. o These gas prices are approximately 72% higher than during the last count in 26. 3

4 Analysis of Count Data The bicycle count information was collected for 15 minute intervals from 3:45pm to 5:45pm on Tuesday, October 7 th and Wednesday, 8 th, 28. Table 1 lists the total count results by location. Location summaries at the end of this report describe the individual count locations and turning movements associated with each location. Several changes to count locations have been made since the study s inception, including the addition and deletion of locations. For this year, three additional count locations were added: Jefferey and Cerro Romauldo (#25), BeeBee and South (#26), and Oceanaire and Los Osos Valley Road (#27). These locations were identified to analyze bicycle usage on Bike Plan identified routes through the Foothill, South Street and Laguna Lake neighborhoods. The station at Mill and the UPRR tracks (#24) was expanded to include bicyclists traveling east and west on Mill Street at the railroad overpass in addition to cyclists riding along the railroad tracks below. For the 2 count, location #1 at Foothill and Los Osos Valley Road was discontinued. This location is not within the City Limits and bicycles at this location would be counted at location #14, Madonna and Los Osos Valley Road or location #21, Foothill Boulevard and Tassajara Drive. Counts at Morro and Leff Street began in 24 as Location #1 to document use of the Bill Roalman Bicycle Boulevard. Table 1 - Total Bicycle Count Results by Current Year s Highest Volume * Counts at the Mill and Railroad location counted bicycles on Mill Street for the first time in 28. ** Stations 25, 26 and 27 are new for 28. 4

6 As new bicycle facilities are developed or improved, the counts at existing locations may vary as bicyclists change their routes to make better use of these facilities. As the population changes, the City may gain new bicyclists. External influences, such as gas prices or weather, may also change ridership trends. One goal of this count program is to develop a trend line to measure how bicycle usage on the City's major transportation corridors is changing over time. Because of the types of fluctuations described above, it is necessary to have several data points for each location to accurately determine a trend. Five or more data points will be collected before a positive or negative trend in bicycle usage is determined at a particular location. The following charts help to show trends for bicycle ridership in the City and their relationship to other factors, such as weather, gas prices, and population. Figure 3 No direct correlation between the weather and count volumes can be established. 6

8 Data was collected for the first time in 28 on bicycle helmet usage and sidewalk riding for each location. In particular, the sidewalk riding information is useful to identify locations where bicyclists may not feel safe riding in the roadway. No conclusions are made based on this base year data. Figure 6 Observed helmet usage per location as a percentage of the total location volume. Figure 7 Observed sidewalk riding per location as a percentage of the total location volume. 8

9 Conclusions The total count of bicycles has increased for the eighth year in a row. The total count number was 44% above that of 26. Figure 2, on page 5, comparing the average volume at City and Cal Poly locations, further illustrates this upward trend. The three new stations for 28 were not included in comparisons. As with past counts, bicycle volumes around the Cal Poly area to the north east of the city are higher on average. The five Cal Poly stations made up 39% of the total volume in just five out of the 24 stations. All five stations increased by at least 6% and each station counted more than 15 bicycles in the two hour time frame, or an average of 1.25 bicycles per minute passing the station. The California & Foothill station (#1) counted a record 496 bicycles in the two hour count period, an increase of 123 bicycles; this was 33% higher than 26 volumes. The trend for the past six years shows an overall increase at many of the count locations. 22 of the 24 stations increased by at least 2% over 26 numbers. The railroad at Mill Street overpass saw a decrease in riders on the railroad tracks, likely due to increased enforcement of trespassing regulations by Union Pacific Railroad in the past year. Every other station saw an increase in ridership. In addition to the higher counts around the Cal Poly area, several other increases indicate an overall increase in ridership. There was a 21% increase at Station #14 (Madonna & Los Osos Valley Road) 4 more bicycles than the 26 count. Station #13 (the Railroad trail at Del Campo) saw a 1% increase, from 38 to 76 bicycles utilizing the trail. Location #19 (Tank Farm & Broad) saw a 14% increase, from 24 to 49 bicycles. And count location #6 (California & Monterey) saw a 93% increase, from 9 to 174 bicycles in the two hour period. With total bicycle counts up 44% from 26, the highest recorded count location, and an upward trend for average bicycle volumes, the counts for 28 are encouraging for the City s goal to reduce the use of private motor vehicles. This count information will be used by transportation planners and engineers to plan for future bikeway facilities, to evaluate bicycle travel patterns, and to continue to extend the bicycle network for the City of San Luis Obispo. 9

The bridge is located at the end of the first section of the Railroad Safety Trail, which extends to Orcutt Rd. Ella Street, which is adjacent to this location, is identified in the Bicycle Transportation Plan as a possible location for a bicycle boulevard. #24 Railroad & Mill 12 1 Railroad at Mill Mill at Railroad Bridge The count station at Mill and the UPRR overpass was originally chosen to monitor bicycle volumes using only the tracks. This year, the station was expanded to include bicycle volumes crossing the tracks on Mill St. This station was the only location with a reduction of volume when compared with 26 count data. It is trespassing to enter the UPRR right of way. 26

27 #25 Jeffrey & Cerro Romauldo 4 35 Jeffrey & Cerro Romauldo The station at Jeffrey and Cerro Romauldo is new for 28, and was chosen to monitor bicycle volumes traveling through the Highland neighborhood on Cerro Romauldo. This route is identified in the Bicycle Transportation Plan as a possible location for a bicycle boulevard. The current count time period may not capture this location s highest volumes, which are expected to be generated by elementary school children going to/from Bishop s Peak, Teach, and Pacheco schools. This location will continue to be monitored in future counts. #26 BeeBee & South 6 5 BeeBee & South The station at BeeBee and South Street is new for 28, and was chosen to monitor bicycle volumes traveling through the South Street neighborhood on BeeBee. It was also chosen to help more accurately show the bicycle volumes in the vicinity of the Higuera / South / Madonna intersection. This location will continue to be monitored in future counts. 27

28 #27 Oceanaire & LOVR 45 4 Oceanaire & LOVR The station at Oceanaire and Los Osos Valley Road is new for 28, and was chosen to monitor bicycle volumes traveling through the Laguna Lake neighborhood on Oceanaire. This location will continue to be monitored in future counts. 28
