Description:  <DIV STYLE="text-align:Left;"><DIV><DIV><P STYLE="text-align:Justify;"><SPAN>The Noise indicator measures direct proximity to the highway network. To measure noise, the home is the point to measure the proximity to highway nuisance. Measuring proximity to highway noise involves creating a buffer, computing the catchment area and areas without noise, standardizing the percentage areas without noise in each census tract to the regional average, and standardizing the percentage of the area covered by the buffer in each census tract to the regional average. </SPAN></P><P STYLE="text-align:Justify;"><SPAN><SPAN>Highway traffic noise is one of the most damaging environmental nuisances for the population. Low-income people and minorities tend to live in areas with high road traffic noise. Studies have shown that children under 15 years old, people 65 years of age and over, with continued exposure to high road noise levels, can trigger many problems in their health and well-being. They are the most vulnerable groups affected by high road traffic nuisance levels. </SPAN></SPAN></P><P STYLE="text-align:Justify;"><SPAN><SPAN>Road traffic noise mitigation practices such as noise barriers have been constructed along highways that traverse residential areas, but the increasing traffic counts on those highways have diminished their effects. Considering the negative impacts of highway traffic noise on children under 15 years old, people 65 years of age and over, minorities, and low-income people, close attention should be paid to these population groups when undertaking transportation policies and investments. </SPAN></SPAN></P><P STYLE="margin:0 0 11 0;"><SPAN STYLE="font-weight:bold;font-size:10pt">Data Source(s)</SPAN><SPAN STYLE="font-size:10pt">: Caltrans Linear Referencing System (LRS) Database, Highway Performance Monitoring System (HPMS) Data (2019).
