Preventing Traffic Deaths -The Critical Role of Clinicians
Traffic collisions are a leading cause of death for both adults and children in Los Angeles County. Clinicians have an opportunity to support Vision Zero, a multidisciplinary effort to end traffic fatalities in LA County. In the July 2019 issue of Rx for Prevention, DPH describes concrete actions clinicians can take to advance traffic safety including: engaging patients in conversations about practicing safe transportation behaviors, sharing their first-hand experiences about victims of traffic collisions to promote culture change, advocating for local policy changes, and encouraging their patients to get involved with local advocacy efforts.

Health Effects of Air Pollution Associated with Development Near Freeways and High-Volume Roads (March 2019)
Studies indicate that residing near sources of traffic pollution is associated with adverse health effects including asthma in children, impaired lung function, and cardiovascular disease morbidity and mortality. Given the preponderance of highly trafficked roadways in Los Angeles County and existing and new development near these roads, the Los Angeles County Department of Public Health prepared "Public Health Recommendations to Minimize the Health Effects of Air Pollution Associated with Development Near Freeways and High-Volume Roads.” These recommendations are intended for developers, planners, government officials, and others working on development within your jurisdiction.

How do pedestrians fare in motor vehicle collisions?
DPH used data from the Los Angeles County Emergency Medical Services Agency trauma database to evaluate outcomes for people hit by a car while walking. Over a two-year period, 4713 people were hit and 235 of them died – that’s two people per week (see infographic). People hit at speeds greater than 20 mph were more likely to be injured, disabled or die than people hit speeds under 20 mph (see brief).

Direct costs of medical care for bicyclist and pedestrian victims
To place in perspective the economic losses that result from motor vehicle crashes, DPH calculated the minimum direct costs of medical care for pedestrian and bicyclist victims of motor vehicle collisions in Los Angeles County. In 2014, direct costs were $63.4 million (see brief and methods).

Step by Step LA County: Pedestrian Plans for Unincorporated Communities
Step by Step LA County provides a policy framework for how the County proposes to get more people walking, make walking safer and support healthy active lifestyles and includes Community Pedestrian Plans with pedestrian safety projects for the unincorporated communities of Lake Los Angeles, Walnut Park, Westmont/West Athens, Whittier-Los Nietos.

Free Trees for Unincorporated Residents
Trees cool our neighborhoods, clean the air and water, improve our health, and save energy. Unincorporated LA County residents can request a free street tree from Public Works! Visit their Parkway Trees website and click on Tree Planting to request yours.

If you live in the City of Los Angeles, visit the City Plants website to request free trees for your home or neighborhood.  

Vision Zero
Traffic collisions are on the rise in unincorporated Los Angeles County. Between 2013 and 2017, fatal collisions increased nearly 28 percent. Three hundred eighty-three (383) people lost their lives during that 5-year period. Each year, on average, over 80 people are killed each year in traffic collisions with more than 500 severely injured on roadways the County maintains.

To address this public health threat, Los Angeles County has released a draft Action Plan to guide a new traffic safety initiative focused on eliminating traffic-related deaths on unincorporated County roadways by 2035. The new initiative, Vision Zero, involves multiple County departments and the California Highway Patrol who are collaborating to focus resources to the areas with the highest concentrations of fatal and severe injury collisions. Visit VisionZeroLACounty.com to learn more about this important initiative. Provide your input and feedback on the draft Vision Zero Action Plan by Sunday, March 31, 2019, at VisionZeroLACounty.com

The development of the draft Vision Zero Action Plan is in response to a February 2017 motion directing County staff to move forward with a Vision Zero initiative for unincorporated areas. The motion instructed staff to implement the strategies described in a February 2017 Vision Zero Report that presented data on traffic deaths and severe injuries in unincorporated areas and recommended specific actions for moving forward. The DPH PLACE Program is co-leading this initiative in partnership with the County Department of Public Works.

In January 2017, the City of Los Angeles released a Vision Zero Action Plan and Safety Study. Together, they describe the landscape of traffic deaths and severe injuries on Los Angeles’ streets, and identify concrete next steps to reduce them. The Action Plan and Safety Study resulted from a 2015 Mayoral Directive that established the goal of eliminating traffic deaths in the city by 2025 and reducing deaths by 20% by the end of 2017. Vision Zero uses a data driven approach to identify where and why traffic collisions occur and implements proven solutions to reduce loss of life. These comprehensive solutions include engineering, education, and enforcement strategies; ongoing evaluation to ensure effectiveness; and an emphasis on equity and engagement to prioritize community needs. Several PLACE staff were embedded in the City’s Transportation Department and tasked with supporting efforts to promote walking in the City.

Youth-Led Community Tree Planting Project
 In February 2017, Supervisor Hilda Solis launched a tree planting initiative called “Life is Better with Trees” that will help provide shade, clean air, cooler temperatures and a better quality of life for residents in urban neighborhoods. The PLACE team is collaborating with the District 1 office, Los Angeles County Department of Public Works, the San Gabriel Valley Conservation Corps and other community partners as a project of the Healthy Design Workgroup’s Tree Committee.

Over 2,000 trees will be planted in Valinda, Bassett, Walnut Park and East Los Angeles. The Community Parks and Recreation Plans were used to identify low tree canopy neighborhoods. A new public education and community engagement model is being piloted in which community organizations from these neighborhoods recruited local, at-risk youth who were trained to provide tree education and outreach to residents.

The Conservation Corp is also providing rigorous job and life skills training to young adults who will also be trained to plant the trees, while working on their GED or required community service. It is hoped that these collective efforts will result in higher acceptance rates of trees, better tree survival, and overall improvements in the social determinants of health in these neighborhoods.

Building Awareness about Equity and the Social Determinants of Health
The social determinants of health are the conditions in which people are born, grow, live, work, and age. These circumstances, such as access to high-quality education, housing, and financial resources, are the most responsible for health inequities - the unfair and avoidable differences in health status seen within and between communities. Building broad awareness and understanding of the social determinants of health and the policies that have created health inequities is an important step to move towards racial equity, social justice, and healthier communities. In order to support this goal, the PLACE program developed two GIS Story Maps: “Hidden Health Hazards: How Our Environments Shape Us” and “Let’s Walk!” The Story Maps can be embedded and linked from any website, and should be broadly used for education to connect the dots around what determines health and overcoming barriers to walking. In addition, the PLACE program is supporting the Department of Regional Planning’s (DRP) Equitable Development Work Program through the Healthy Design Workgroup. DRP reports regularly to the Board with status updates.
