Exploring How Income, Race and Design Affect Pedestrian Casualties

Pedestrian, Car, Street

Lower income communities experience fully three times the number of pedestrian deaths and injuries per capita as do affluent ones.

Pedestrian fatalities in the United States have increased more than 50% over the last decade, with 1 in 6 traffic deaths involving pedestrians. Programs like Vision Zero and Safe Systems focus on making transportation safe for vulnerable users, primarily pedestrians, based on the assumption that pedestrian-related improvements will enhance safety regardless of where they are applied.聽

Despite the widespread implementation of these programs, they have generally failed to reduce traffic-related deaths and injuries. Even cities that have most aggressively adopted Vision Zero, like New York, Washington D.C., Seattle and Portland, have seen increases in traffic-related fatalities and injuries after implementing these programs.

Research from 澳门六合彩历史记录 examined the environmental factors associated with crash incidence in lower-income and more affluent areas in Broward and Palm Beach counties, finding that much of the failure of these programs may be attributed to the failure to direct pedestrian safety improvements to the areas and populations that would most benefit from them. 聽

Results of the study, published earlier this year in the journal , show that the nature of pedestrian crash risk is markedly different in lower income communities than in more affluent ones. Lower income communities experience fully three times the number of pedestrian deaths and injuries per capita as do affluent ones. 聽

The environmental factors associated with crash risk in these areas differ as well. For lower-income communities, pedestrian deaths and injuries increase with traffic volumes, multilane streets, and presence of restaurants and shopping centers. These variables all suggest that, at least in lower-income areas, pedestrian death and injury is associated with difficulties safely accessing household-supporting destinations.

For affluent areas, the factors associated with increased pedestrian death and injury were those relating to recreation and nightlife 鈥 specifically, bars and clubs, hotels and restaurants 鈥 rather than essential household travel. Neither high traffic volumes nor multilane 鈥渁rterial鈥 roads, which tend to be the focus of Vision Zero-related safety programs, were meaningfully related to pedestrian death or injury in affluent areas.

Although pedestrian crashes often are attributed to pedestrians walking under the influence of drugs or alcohol, it appears that walking under the influence is principally an issue for affluent populations, rather than lower income ones. Bars and nightclubs were only associated with increased pedestrian crashes in affluent areas, with pedestrians struck by a vehicle in affluent ones being twice as likely to have been suspected of being under the influence of drugs and alcohol than those in lower income ones.

鈥淧edestrians in lower-income areas are likely to be struck by a car because they are trying to access everyday needs like food and shopping in environments that are poorly designed,鈥 said Eric Dumbaugh, Ph.D., senior author and a professor in the Department of Urban and Regional Planning, within 澳门六合彩历史记录鈥檚 Charles E. Schmidt College of Science. 鈥淭his isn鈥檛 the problem in affluent areas. If a street feels unsafe, they don鈥檛 need to walk. They simply drive instead.鈥澛

The researchers note that streetscape projects intended to advance economic development objectives or to enhance the lifestyle preferences of affluent communities are often heralded as 鈥渟afety improvements,鈥 despite little evidence to suggest that such improvements will result in reductions to crash risk. 聽

鈥淭here is a tendency to prioritize pedestrian projects in affluent areas where pedestrian safety isn鈥檛 really a problem. If we want to get serious about pedestrian safety, we need to begin directing safety improvements to the areas that will most benefit from them,鈥 said Dumbaugh. 鈥淟ooking forward, the definition of vulnerability incorporated in road safety programs needs to be understood not simply as a function of a human body鈥檚 physical tolerance for trauma, but also as an outcome of underlying social disparities, with race and income particularly relevant risk factors.鈥
