Brookglen Stormwater Detention Basin <br />Traffic Impact Study <br />All the roadways within the study area are two lane local roads with a posted speed limit of 30 <br />mph with stop controls. There are no signalized intersections in the study area. Total daily traffic <br />on Somerton Drive is 1565 and Gladwyne Lane is 492 vehicles per day. <br />Pedestrian Access: There are no sidewalks along any of the roadways within the study area. <br />There are no pedestrian crossings at any of the study intersections. <br />Bicycle Access: There are no bicycle lanes in the study area. <br />On-Street Parking: On Street parking is allowed on all the roadways within the study area as they <br />are considered local roads. <br />Peak hour volumes and turning movement counts for the weekday AM and PM peak hours at all <br />th <br />study intersection were collected on Tuesday, August 25 <br />, 2021. Weekday AM peak was <br />observed from 7:00 to 8:00 AM and weekday PM peak was observed from 5:00 to 6:00 PM. 24- <br />hour daily traffic counts were also collected on Somerton Drive and Gladwyne Lane on the same <br />day. Summarized turning movement counts and daily counts are included in Appendix A. <br />3 ANALYSIS <br />The impact analysis of the proposed abandonment includes safety analysis, redistribution of trips <br />onto the street network, and analysis of peak hour operations. Each of these analysis techniques <br />and their results are described below. The study focused on weekday AM and PM peak hour <br />scenarios. <br />3.1 Safety Analysis <br />Crash data was collected using ÐCrash Records Information System (CRIS)Ñ website hosted by <br />the Texas Department of Transportation. Between 2018 and 2020, there are a total of 14 <br />crashes in the vicinity of the subdivision. Out of these, 7 crashes involved hitting a parked car on <br />the street. No crashes occurred on the streets or at the study intersections within the study <br />area. Table 1 summarizes the crashes by first harmful event and manner of collision. Figure 4 <br />depicts where the crashes occurred within the region. The safety analysis using CRIS data <br />indicates that there is no significant safety issue in the study area. <br />3|Page <br /> <br /> <br />
