Short CommunicationAre single entry communities and cul-de-sacs a barrier to active transport to school in 11 elementary schools in Las Vegas, NV metropolitan area?

- ATS rates have declined significantly over the last four decades.
- SECs and cul-de-sacs increase trip distance and minimize route choices.
- More SECs and cul-de-sacs were associated with less ATS some/all of the time.
- Current urban design may be creating a barrier for school aged children to utilize ATS.

Single entry communities (SECs) and cul-de-sacs minimize route choices and increase trip distance. Las Vegas' built environment facilitates the examination of these variables and active transport to school (ATS) rates. The purpose of this study was to examine the influence of SECs and cul-de-sacs on ATS rates in Las Vegas, NV elementary children. Parental-reported data was collected from 11 elementary schools on ATS rates (n = 1217). SECs and cul-de-sacs were quantified for each school zone. Logistic regression models were used to predict ATS. 23.9% of students reported ATS all of the time and 31.4% some of the time. SECs per school zone ranged from 0 to 25 (mean = 11.9). Cul-de-sacs ranged from 12 to 315 (mean = 138.3). Some ATS use was predicted by distance from school (p ≤ 0.001;OR = 0.61), parental education (high school: p = 0.004;OR = 0.53, some college: p = 0.001;OR = 0.50, 4 year degree: p = 0.004;OR = 0.52) and cul-de-sacs (p ≤ 0.001;OR = 0.99). A separate model using distance from school (p ≤ 0.001;OR = 0.61), parental education (high school: p = 0.002;OR = 0.51, some college: p ≤ 0.001;OR = 0.45, 4 year degree: p ≤ 0.001;OR = 0.45) and SECs (p ≤ 0.001;OR = 0.96) predicted some ATS. All ATS use was predicted by distance from school (p ≤ 0.001;OR = 0.58), parental education (Grades 9-11: p = 0.05;OR = 0.61, high school: p ≤ 0.001;OR = 0.45, some college: p ≤ 0.001;OR = 0.41, 4 year degree: p ≤ 0.001;OR = 0.38) and SECs (p ≤ 0.001;OR = 0.97). A separate model using distance from school (p ≤ 0.001;OR = 0.58), parental education (Grades 9-11: p = 0.041;OR = 0.59, high school: p ≤ 0.001;OR = 0.47, some college: p ≤ 0.001;OR = 0.44, 4 year degree: p ≤ 0.001;OR = 0.43) and cul-de-sacs (p ≤ 0.001;OR = 0.99) predicted all ATS. Current findings reveal that both SECs and cul-de-sacs were predictors of ATS beyond distance. Students with more SECs and cul-de-sacs in their school zone were less likely to utilize ATS.
