We can now understand how people experience cities, and these insights can provide a roadmap for creating more just, sustainable and healthy places.<\/p>\n<p>Assuming people approve of these technologies surveilling them, researchers like us can collect real-time facial analysis and eye-movement data using webcams. We can then discern subconscious information communicated by people\u2019s faces when they are engaged with different urban scenes. For example, did they smile? What did they look at first? How long were they engaged with what they saw?<\/p>\n<p>Our\u00a0<a href=\"https:\/\/as.tufts.edu\/uep\/resources-community\/field-projects\" target=\"_blank\" rel=\"noopener\">research\u00a0<\/a><a href=\"https:\/\/as.tufts.edu\/uep\/resources-community\/field-projects\" target=\"_blank\" rel=\"noopener\">group<\/a>\u00a0at\u00a0<a href=\"http:\/\/as.tufts.edu\/uep\" target=\"_blank\" rel=\"noopener\">Tufts University<\/a>\u00a0has conducted a\u00a0<a href=\"https:\/\/www.tandfonline.com\/doi\/abs\/10.1080\/02697459.2020.1768332\" target=\"_blank\" rel=\"noopener\">number<\/a>\u00a0of facial analysis and eye-tracking\u00a0<a href=\"https:\/\/link.springer.com\/article\/10.1057\/s41289-020-00122-w\" target=\"_blank\" rel=\"noopener\">studies<\/a>, and sifting through these data we see that people do not like looking at cars. Conventional urban design and planning practice relies on people\u2019s subjective assessments of places they spend time in through surveys or interviews. This new kind of information and other examinations of how people perceive their environments could revolutionize the way we design urban developments because we believe we can better take into account people\u2019s preferences before we start planning how they will use and navigate them.<\/p>\n<p>This research builds on previous\u00a0<a href=\"https:\/\/islandpress.org\/books\/roadways-people\" target=\"_blank\" rel=\"noopener\">work<\/a>\u00a0establishing the social and health benefits of car-free urban spaces, but employs a biometric lens; by measuring unconsious reactions to different scenes, we now have empirical evidence of the harm caused just by seeing cars. These results reinforce\u00a0<a href=\"https:\/\/www.tandfonline.com\/doi\/abs\/10.1080\/00038628.2021.1929055\" target=\"_blank\" rel=\"noopener\">other research<\/a>\u00a0that likewise demonstrates the value of using eye-tracking and facial expression analysis to guide urban design and planning.<\/p>\n<p>While the range of factors governing our reaction to space is as vast as the range of human emotion itself, our most recent project uncovered a statistically significant increase in positive emotions when people viewed urban streets without cars versus ones with cars on them: people appear to be happier when cars aren\u2019t in the picture\u2014literally. This research helps us to quantify the benefits of car-free spaces when urban planners are considering how to make their cities more welcoming and pedestrian-friendly.<\/p>\n<p>For this study of car-free streets, we used\u00a0<a href=\"https:\/\/imotions.com\/affectiva-requestdemo\/\" target=\"_blank\" rel=\"noopener\">iMotions Online AFFDEX<\/a>\u00a0facial coding software to track 51 participants\u2019 real-time visual attention and facial expressions in response to images and videos of Memorial Drive in Cambridge, Mass. This is a popular street closed to vehicle traffic on weekends during certain times of the year. We captured similar images of the same stretch of road with and without cars and compared our participants\u2019 emotional reactions to both types of images. The system records a person\u2019s eye movements and facial expressions with a camera. Then the software uses an algorithm to score whether a participant displayed positive, negative or neutral emotions during each millisecond of the study based on subtle movements in their facial muscles.<\/p>\n<p>Although our participants expressed neutral emotions in response to the images 85 percent of the time, participants spent on average 0.4 percent more time expressing positive emotions in response to vehicleless images and videos. While seemingly a small difference, any measurable effect from a still image can signal something worth considering in a real-world setting where people are surrounded by cars.<\/p>\n<p>To further explore whether these differences were meaningful, we compared both emotional responses and visual fixation patterns in response to vehicle-free spaces by using a statistical method that allowed us to control for possible confounding factors. People in the study spent more time showing positive emotions when they looked at images without a vehicle in the foreground compared to images with cars. In addition, our eye-tracking data showed that people\u2019s eyes spent more time on the areas of images where vehicles are present rather than absent. People\u2019s eyes are drawn to cars, but their emotional responses are more negative while looking at them.<\/p>\n<p>Scientists and urban planners globally are beginning to\u00a0<a href=\"http:\/\/sites.tufts.edu\/uxdesign\" target=\"_blank\" rel=\"noopener\">tinker with biometric tools<\/a>\u00a0to understand these kinds of behavioral responses to urban and architectural elements.

Our nervous system responds to stimuli\u2014especially hand motions, faces and voices\u2014and helps us decide if we are in a safe or dangerous situation. In social contexts familiarity further enforces safety and helps us interpret the\u00a0<a href=\"https:\/\/doi.org\/10.3949\/ccjm.76.s2.17\" target=\"_blank\" rel=\"noopener\">facial features<\/a>\u00a0of another person as warm or friendly.

For example, recent research explains how \u201cconviviality,\u201d or the \u201cfriendliness\u201d of a space, is more challenging to foster in a car-centric environment.<\/p>\n<p><a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S0048969716325578\" target=\"_blank\" rel=\"noopener\">Natural elements<\/a>\u00a0like trees and shrubs are less foreign to our brain than car-related infrastructure like roadways and curbs, and align more with our innate preferences, according to our findings and other\u00a0<a href=\"https:\/\/www.routledge.com\/Urban-Experience-and-Design-Contemporary-Perspectives-on-Improving-the\/Hollander-Sussman\/p\/book\/9780367435554\" target=\"_blank\" rel=\"noopener\">research<\/a>. Furthermore, natural design elements make it easier for humans to relax and enjoy their surroundings as they reflect the natural surroundings of our environment. Car-free spaces are important in community building.
