Goal

  • Increase the parking completion rate to 80%

  • Report rate lower than 5%

IMPACT

  1. Build a mutual reporting mechanism to ensure the interests of all parties.

  2. Boost host earnings, cut costs, and scale up operations.

  3. Ensure a user-friendly parking experience, increasing users parking completion rate.

WHAT CHALLENGES WE  FACE

  1. How to design a scalable system that protects the interests of all three parties?

  2. How to reduce user operating costs while allowing them to increase revenue?

  3. How to improve the completion rate of the parking process without affecting the user experience?
     

Design Method

40% Primary Research + 60% Secondary Research

The design originated from complaints by parking space owners, who felt that the three-hour interval needed to be shorter. Additionally, the original design lacked a mechanism to penalize violators.

3 Principles for Designing a Mutual Verification System 

1

Business

Ensure All Parties Interests

How to ensure the interests of all parties and maximize the rights of parking space owners, because if parking space owners cannot make money, we will lose both space owner and driver.

2

Priority of Information

Reduce Host’s Operation Cost

Efforts are underway to reduce hosting costs. However, without hardware or third-party tools to confirm exits, we must find a solution for hosts to avoid losing their cooperation.

3

User Experience

Ensure Complete Parking Process

Hosts and drivers may not finish the process for various reasons. How can we remind them to increase the parking completion rate at a minimal cost?

Challenge 1

How to Design a System to Ensure All Parties Interests

  • How to reduce customer service costs and attract drivers?
  • How to prevent drivers from being unfairly overcharged?
  • How to charge the overtime parking?
Solution 1

3 Rules to Ensure All Parties Interests

The main challenge in Exit mechanism design is balancing interests among three parties: the company seeks cost reduction, hosts aim for higher earnings, and drivers want lower payments. Using a balanced scorecard approach, each party receives 2 advantages (red) and 1 disadvantage (green) to achieve balance.
01 One-hour Buffer Time
​After conducting thorough research, we've found that our users typically park to run errands nearby or catch the subway into Manhattan. A one-hour buffer time should suffice.
02 Overtime Reporting Mechanism
Hosts: To start overtime billing, we require hosts to upload photos to minimize disputes and reduce operational costs.
Driver: There's no mandatory photo upload for drivers, given the diverse nature of driver issues.
03 Automatic Overtime Billing
Since hosts may not be at home, to ensure host rights, we will activate overtime billing after the 1-hour buffer period ends, reducing operational costs and enhancing fairness. From the driver's perspective, they are already overtime and should pay the fee.
Challenge 2

How to Reduce the Hosts Operation Cost but Increase Revenue?

  • How to handle the overtime billing without in person?
  • How busy is the host in completing the exit process?
  • How to maximize the host’s earnings?
Solution 2

Reduce Operating Costs for Hosts

截圖 2024-04-07 上午11.14.01.png
01 Automatic Overtime Billing
Considering that drivers may not be at home to rent out parking spaces and confirm immediately, the system will activate overtime billing if drivers still haven't responded after the one-hour buffer period.
02 Auto-Settlement on Next Day, 4am
Despite the host's lack of response, if the previous driver has left, the parking space can be opened for others. Research shows that the Bronx sees minimal traffic at 4 AM, prompting the system to clear spaces daily at that time. This allows hosts to earn passive income even if unresponsive.
03 Manual Verification of Exit
We offer a route for manual verification of exit. As soon as the driver's parking time ends, hosts can verify. The earlier they verify, the higher the turnover rate and the more they can earn
Challenge 3

 How can we improve the completion rate of the parking process without affecting the user experience?

  • How to lower driver’s operation cost in the process?

  • How to increase completion rate for hosts and drivers in the exit process?

  • How to boost host willingness to complete the process?

Solution 3

Quick Exit Menu + Notification + Host Landing Page as Dashboard

截圖 2024-04-07 下午2.15.33.png
01 Quick Exit Menu for Driver
To ensure timely departures for drivers, we've implemented a persistent interface on the landing page. This ensures that drivers can immediately view recent reservations, cancellations, or exit actions upon opening the app
02 A Non-intrusive Notification
To address potential checkout forgetfulness without inundating users with notifications, we've set reminders to trigger only at critical times. For instance, during the buffer period, notifications are sent every 20 minutes. Moving forward, we'll switch to email notifications to enhance the user experience further.
03 Host Landing Page as Dashboard 
Create a dedicated dashboard for hosts, showing each parking status. Users simply need to click on the notification to navigate to the dashboard and complete the parking process
