4 . Priority Focus Areas
To achieve vision zero by 2050 , knowing where to make improvements is essential . For this plan , a high injury network and high-risk road characteristics were identified , along with proven safety countermeasures and solutions .
Focus areas were overlayed with Disadvantaged Communities , defined by the U . S . Department of Transportation ( USDOT ) and identified in their Equitable Transportation Community Explorer , to understand the how transportation safety may be affecting communities in Arlington , and to support materials to apply for additional federal transportation funds to implement projects in Arlington . The U . S . Department of Transportation ( USDOT ) defines a Disadvantaged Community using a composite percentile ranking of five components : Climate & Disaster Risk Burden , Environmental Burden , Health Vulnerability , Social Vulnerability , and Transportation lnsecurity . 1
KAB
Crash Locations
Overall crash trends , presented in What Data Tells Us About the State of Safety in Our Communities , tell part of the safety story . It is also important to know where the most KAB crashes occur and determine how Arlington should prioritize safety investments . To that end , three High-Injury Networks ( HINs ) were developed - a HIN is a collection of streets where a disproportionate number of collisions result in someone being killed or severely injured ( KAB crashes ).
Three HINs - a vehicle and motorcyle HIN , a pedestrian and bicycle HIN , and a HIN showing the confluence of all modes - were developed ( Figure 16 ). Appendix A includes the methodology for developing the HINs . These HINs represent the most KAB crashes for all travel modes . The dashed green line on the HIN map shows where all these crash types overlap . The HINs consider crash data from 2018-2022 , sourced from the Texas Department of Transportation ( TxDOT ) Crash Records Information System ( C . R . I . S .) for Arlington owned streets and TxDOT arterials . The frequency and severity of crashes , and critical crash rate , which considers functional class of the roadway , daily volumes , and crash counts , were used to prioritize streets for inclusion on the HINs .
Privately owned streets and TxDOT limited-access highways ( IH-30 , IH-20 , US 360 , and US 287 ) and frontage roads are excluded from the HINs .
