ParkShare

The Airbnb for Parking. A peer-to-peer marketplace transforming unused driveways and private lots into bookable parking spaces—solving the parking crisis in university campuses, major cities, and high-demand event venues.

For students circling campus lots and urban drivers navigating downtown Chicago, parking is a daily lottery—10–30 minutes of searching, ambiguous rules, and safety fears that erode time and wellbeing. Through 6 in-depth interviews, 5 research-backed personas, and mid-fidelity usability testing with 4 participants (SEQ 6.23/7, 100% task completion), I synthesized findings into a predictive, trust-centered platform concept.

The Story: A Daily Lottery Nobody Wants to Play

"If you get a parking spot, it's like lottery."

— Participant

"As a girl, I feel safer when the lot is more full and there's more light."

— Participant

Picture a student circling a campus lot at 8:47 AM, watching the clock tick toward a 9:00 class. Permits sold out months ago. Event-goers face even higher stakes—forced to move cars before midnight to avoid towing, or walking 10+ minutes in sub-zero temperatures.

The frustration isn't just about scarcity—it's about information, rules, and trust. Street-level signage is ambiguous; participants feel in the clear but still fear boots and tickets.

ParkShare's Systematic Response

Reallocate unused private driveways and small lots into a trusted, bookable network. Aligns with sustainability (less circling, lower CO₂), equity (more access to safe parking), and resource optimization (using underutilized spaces near campus and events).

Research Methodology

Research Goals

  • • Understand how drivers search for, select, and pay for parking
  • • Identify pain points, safety concerns, and rule confusion
  • • Evaluate trust in peer-to-peer private driveway model
  • • Test core ParkShare flows with scenario-based tasks
  • • Translate findings into product strategy and HMWs

Participants

6 interview participants: students, commuters, urban drivers across Ames, Des Moines, Chicago, and Massachusetts. Ages early 20s to mid-30s.

3 usability test participants for mid-fidelity prototype—smartphone users comfortable with navigation and parking apps like ParkMobile.

Methods Applied

Contextual and semi-structured interviews • Codebook development and applied coding • Thematic analysis (6 key themes) • Insight statements with impact/confidence rankings • HMW generation and opportunity–solution tree • 5 research-backed personas • Mid-fidelity usability testing with SEQ ratings • Bias and rigor audit

Early Sketches & Ideation

Before moving to digital wireframes, I explored concepts through rapid paper sketching—mapping out screen flows, testing layout hierarchies, and iterating on information architecture. These sketches helped identify core interaction patterns and surfaced early usability considerations before committing to higher-fidelity designs.

Navigation & Arrival Experience

Key Findings: Six Themes from the Field

1. Reliable Spots Beat the Lottery

Drivers need predictable access to nearby spots, especially during events and peak hours. They adjust schedules, arriving 1–2 hours early to secure spaces.

2. Users Pay for Proximity & Time

Drivers are pragmatic: they will pay higher rates to avoid missing events. "If it's near to that event, I'm willing to pay for it."

3. Trust Rises with Safety Signals

Lighting, occupancy, neighborhood context, and host verification heavily shape perceived safety. P2P parking must feel culturally "normal."

4. Rule Clarity Reduces Anxiety

Ambiguous signs and event-based restrictions cause constant low-grade fear of tickets, boots, or towing.

5. Frictionless Flow = Value

Users avoid lots that are "more fuss than it's worth" and optimize for easy exits and no parallel parking.

6. Emotional Fatigue Is Real

Repeated hassles produce exhaustion. Users crave calm and assurance. "Why should this be a hassle for me?"

Rebook & Favorites Flow

Concept Development + Experience Strategy

Flow 1: Find & Reserve

User enters destination + arrival time; sees predictive availability map with confidence scores; results color-coded by trust level. Spot cards show proximity, price, safety score, and legal status badges.

Flow 2: Navigate & Park

From Booking Dashboard, tap "Navigate to Spot" for turn-by-turn directions. Arrival zone notification at ~50m. Final instructions provide access details and host confirmation.

Flow 3: Host Listing

Income-focused pitch ("Earn $200+/month"). Flow: address → photos + spot type → safety/availability → pricing/protection → publish with projected earnings.

Flow 4: Rebook & Auto-Reserve

"My Bookings" surfaces favorites, offers one-tap "Book Again," and "Auto-Reserve Weekdays" for commuters. Reduces friction for repeat users.

Value Proposition Framework

Predictability: confidence meter, guaranteed spots • Trust & Safety: safety scores, verified hosts, host protection dashboard • Legal Clarity: legality overlay, towing countdown timers • Frictionless Flow: fast exit, skill-based filters ("no parallel parking"), one-tap rebooking. Design frames price as time saved ("You're saving 12 minutes vs nearest garage").

Lo-Fi Prototype

The mid-fidelity prototype was built in Figma to test core flows with real users. These wireframes prioritize information hierarchy, interaction patterns, and content placement over visual polish—allowing validation before investing in high-fidelity design. Each flow tested with 3 participants, achieving SEQ 6.23/7 with 100% task completion.

Overall Average

What Worked

  • ✓ "The UI is simple" — P4
  • ✓ "It met my expectations... similar to Google Maps and Apple Maps, no learning curve" — P4
  • ✓ Navigation feature: "Navigator is going to be so useful because sometimes you forget where you're parked" — P4
  • ✓ Host listing rated 7/7: "Clear prompts that told the user what next to do"
  • ✓ Large CTA buttons guided actions: "literally guided me to what I need to tap next"
  • ✓ Map showing spots within vicinity made selection easy

Design Changes Needed

  • ✗ Search should allow destination entry, not just current location — "You could be going to a different place"
  • ✗ Rebook flow felt incomplete: "I feel like there's a whole path that's missing"
  • ✗ Auto-reserve should pre-fill previous booking info: "having to repeat information"
  • ✗ Add search filters: price (high/low), distance, nearby facilities
  • ✗ Generate booking receipt/ticket as proof of payment
  • ✗ Simplify photo upload at arrival: "Taking an image, going back to the app... that's a lot of stress"

Feature Suggestions from Testing

Book for a Friend: "Can you book for someone? That would be nice."

Nearby Facilities: "Show facilities within that vicinity—food, gas stations."

Confidence Meter Clarity: Users initially confused about what it measures.

"It's a nice app... saves so many people the stress of having to find parking. People with free spaces could rent out and earn money. It's a win-win situation... especially in a place where they have bad parking. Iowa State—your parking system sucks. This would really help."

AI Collaboration as Research Accelerator

As both UX researcher and prompt engineer, I orchestrated structured prompts to turn raw interviews into a full research stack. GPT-5 served as a research augmentation tool—accelerating coding, surfacing patterns, and maintaining analytical consistency while final decisions remained human-led.

Prompt 1: Codebook

Generated initial codebook with 12–20 codes including definitions, inclusion/exclusion criteria, and example quotes.

Prompt 2: Applied Coding

Applied codebook across 6 transcripts, proposed new codes like Lot_Egress_Friction and P2P_Cultural_Legitimacy_Barrier.

Prompt 3: Themes

Synthesized codes into 6 overarching themes: Scarcity, Cost Trade-offs, Trust & Safety, Rule Anxiety, Mobility UX, Emotional Fatigue.

Validation & Rigor

Cross-checked AI-generated codes against raw transcripts and my own notes. Used bias and rigor audit to identify sampling skew and avoid analytical overreach. AI was not a shortcut, but a research augmentation tool.
