Barred Owl Neighborhood * Traffic Calming 

5/17/2021 Update - Latest Data and Traffic Data Primer

Data was previously presented at the March 7, 2020 public meeting.  That data can be viewed here.

Latest Data

Updated data for the 100 and 200 blocks of James Street (South and North of the post office driveway respectively) and for the 100 and 300 blocks of Carol Street can be viewed here.

Traffic Data Primer

To assist with review of this traffic data, definitions of relevant terms are listed below.

Average Daily Traffic – Total vehicles counted over the 48-hour period divided by two.  This is the anticipated number of vehicles over a 24-hr period.

Average Speed – The sum of all speeds collected divided by the total number of vehicles measured.

85th Percentile Speed – The speed at which 85 percent of all vehicles measured are travelling slower than (Alternatively, 15 percent of all vehicles are travelling faster than the 85th percentile).  Often used as a metric for the speed at the road conditions cause most drivers feel comfortable travelling.

Peak Hour Volume – The highest observed hourly volume (number of vehicles counted), used to describe the most intense traffic flow.

Peak Hour – Time of day when the peak hour volume occurs.

A note on data variability: Traffic volumes and speeds are susceptible to variations that occur due to different traffic patterns in different seasons, weather conditions, holidays, et cetera.  The Town typically only collects speed and volume data when both schools (i.e. UNC and CHCCS) are in session.  This past year, due to COVID-19 travel behavior has changed due to an increase in telework and a reduction in people driving to work.  Aside from weather, speed data itself is less susceptible to changes due to seasonality.

Project Update - 7/17/2020

The feedback received from the neighborhood during the March 7th meeting has been used to develop concept level traffic calming improvements to address the issues identified. Internal staff from multiple departments including Police, Fire, and Public Works are reviewing this concept plan. The current conditions of COVID-19 prevent us from holding any additional public input sessions at this time. We are working to create an opportunity for residents to give feedback and to have a discussion on neighborhood preferences for access control at Carol Street. We are currently planning to provide an update to the Town Council early in the fall. 

In the meantime, if you observe any unsafe driving behavior occurring in your neighborhood, please direct any information you may have to the Carrboro Police Department’s non-emergency line at: 919-918-7397 or via email to deptpd@townofcarrboro.org.  

However, if you observe behavior that is egregiously unsafe, do not be hesitant to call 911.

Additionally, we’ve developed some temporary signage which can be installed along the streets to help better inform drivers to expect pedestrians walking in the street due to current social distancing requirements.

A version of the sign that you can print for your own use can be found here.

Town Staff are currently working to develop a concept plan to provide potential options for traffic calming alternatives to alleviate the issues identified during the March 7th meeting. Due to the current restrictions the Town has put in place to better limit the spread of COVID-19, we do not have a timeline for when we would anticipate future meetings to discuss traffic calming recommendations or questions about the Lloyd Farm Traffic Impact Analysis.

Any additional questions or comments can be submitted to the Town’s Transportation Planner via email at zhallock@townofcarrboro.org or at 919-918-7329.
