How do cars and people interact on the roads and in street-adjacent spaces?
In collaboration with Dr. Melissa Cefkin from the Alliance Innovation Lab and and Dr. Jan English-Lueck from SJSU, we considered the ways different autonomous vehicle users interact on the roads and in urban spaces. As the Alliance Innovation Lab develops increasingly automated vehicles, their researchers asked us to help them better understand the interaction of autonomous vehicles with people in street-adjacent spaces. Our research explored a future of parking by documenting the social world of valets.
The Problem
Our team’s goal was to better understand what valet service meant to the different stakeholders involved in the process and practice of valet. After exploratory visits to the field, we narrowed our research focus to two main topics: safety and organization.
How do cars and people move through valet spaces, and what does moving through those spaces mean to them?
How do the valet workers understand the organization of valet service and spaces, and how is that the same or different from how the people who use valet imagine these things?
How is value created for different actors in the practice of valet, and how does valet fit into a larger system of care?
Our team of four researchers completed this project over 11 weeks.
My Role
I was a key contributor for this project, working with my team to establish the problem space, collect and analyze our data. I was the lead cinematographer, conceptualizing how video could capturing original video footage and editing together our final video deliverable.
Research Strategy
Defining the Problem
Social media research
To identify key topics before going into the field, we reviewed the social media reviews of our intended sites - hotels in downtown San Jose. This gave us insight into what customers of valet service cared about.
These reviews fell into several large topics: safety of property, timeliness, service, and cost.
Exploratory Site Visits
Our team conducted exploratory site visits to observe valet service at several potential downtown sites and conduct informal interviews to hear from valet workers how they thought about their work. These visits helped us select our final research sites and allowed us to begin to build rapport with valet workers.
Literature Review
We read other research to inform our understanding of how people and material things negotiate public and private spaces. This reading included topics like care and transportation systems, and mobility.
Gathering Primary Data
Semi-structured interviews
We interviewed valet workers, a valet supervisor, and a frequent valet customer.
Our interviews helped us obtain information on:
General background on interviewee’s work with valet/use of valet
How the interviewee situationally identifies his/her beliefs and attitudes about safety and organization
What the routine of valet service is from first contact to last
The techniques and technologies used by valet staff to ensure safety and organization
The perceived consequences of the use of techniques and technologies valets’ work with, and what values each user considers
Reflections on the future of valet services
Informal Interviews
During our observations, we chatted with the valets during lulls in their work. This helped us understand how they thought about their use of and movement through space, both public and private, and what they thought was important in their valet services.
Ethnographic observations
Our team spent over 40 hours observing valet service at two downtown San Jose hotels.
We watched for how valets, valet customers, ride share drivers, and pedestrians (or other hotel guests) interacted in the valet space, including looking for:
Intended & unintended convergences between street users
Movement of different street users (including valet drivers, non-valet drivers, rideshares, and pedestrians)
How valets’ managed the flow of people and traffic, including where cars stopped, where loading and unloading occurred, and how valets utilized public space (like sidewalks) along with private space (hotel driveway)
Spatial mapping
To better visualize what we observed, we created spatial maps of our two research sites (we used this set of codes, developed ahead of time, to drive our spatial mapping)
Analyzing the Data
Qualitative pattern analysis
Using our data, we identified several key areas in valet service by identifying reoccurring themes and grouping them into broad categories. These themes included:
Time (efficiency, convenience, time savings)
Personal property (safety of property and liability for damage to property)
Human bodies (safety of bodies and ways valets use their bodies in valet service)
Technologies used by valets to accomplish the preceding themes (software, tickets/paper tags, mental models of organized space, the valets’ bodies)
We also drew from our interview data to consider the future of valet services.
Futures that are disruptive to valet service worlds
Impacts of rideshare services
Changes to the customer experience
Finally, we considered how a potential future of autonomous vehicle fleets might perform ‘care at scale’
Spatial mapping analysis
We considered the themes identified in our interview and observational data to consider how our spatial mapping might highlight some of these things.
Unintended convergences - When valet workers converged with other street users (non-valet drivers, rideshare drivers, pedestrians, etc.) in an unintended way.
These moments highlighted potentially unsafe moments - moments that could cause bodily harm or property damage. Interestingly, these moments occurred most frequently at the edges of the official valet spaces.
This showed how spots where public and private spaces met were potentially sites of a breakdown of safety, one of the most important parts of valet service to both the valets and customers.
Pedestrian movements - The ways pedestrians navigated the valet space, which included a portion of public sidewalk at both our sites.
Mapping pedestrian movements helped us see how people who are not in vehicles look for safe spaces. Pedestrians avoided much of the valet space within the driveways, but would freely use the sidewalk space. This was true even at the valet site that utilized the sidewalk as part of their valet driveway - often parking cars there and directing rideshares through that space.
Pedestrian movements helped us identify spaces they saw as safe, by asking what spots pedestrians used, where did the hurry, and what did they avoid?
Organization - Valets used both mental models of their space (assigning spots within the driveway as parking spaces) and the physical items in their spaces to organize their service in both public and private spaces.
One interesting deviation was in rideshare behavior. Although valets stuck quick closely to using the space as the described it to us, rideshares did not use the space the way valets told us they were supposed to. This including driving through the private valet space when they were not supposed to.
Each site had a different amount of space. Although the flow of valet service moved similarly through each site’s space, the space limitations at one site significantly increased the valets’ use of public sidewalk space.
We broke our analysis out into topics and sections on post-it notes and used those to map our video storyboard, as seen in this image, considering what point of view we would tell our story from.
From this initial storyboard, we wrote our script and created our final video deliverable, which you can watch below.
Final Deliverable
Our team presented this video detailing our findings for Dr. Cefkin and her team. Our goal for this video was to provide a succinct summary of our findings that could be easily shared with Dr. Cefkin the day of our presentation, which also included time for questions and answers, as well as providing a way for Dr. Cefkin to share our results with her team when we would not be present.
TL;DW
Valet drivers and their use of space are defined by flexible and critical thinking.
Important aspects of valet - valets are oriented to care of:
Time
Safety of Personal Property
Protection from Injury
Valets use different technologies like radios, signs, paper tags, and software to help enact this care and navigate a variety of street users (including pedestrians, rideshare drivers, and other non-valet drivers).
Valet workers organization includes public and private spaces, and navigating other users in those spaces.
When imagining a future of valet with increased number of autonomous vehicles, valet workers feel there will always be a need for their services to enact this system of care.
We suggest customers will continue to search out what they value in valet service, including convenience, luxury, and protection of personal property.
