Case study

Multimodal Ride-Hailing

The proposed multimodal ride-hailing platform aimed to solve the lack of transportation options during peak hours for the approximately 4.43 million daily commuters from Seoul to satellite cities. It was designed to provide a cost-effective and efficient mode of transportation by accommodating up to 15 passengers per vehicle.

To improve the daily commute for the roughly 4.43 million people who travel from Seoul to the satellite cities, we suggested a shared ride-hailing service that operated during peak hours. Multi-modal vehicle hailing aimed to bridge the transportation gap between the two regions.

In Seoul, approximately 4.43 million individuals commute to the satellite cities on a daily basis, yet there is a dearth of transportation services during peak hours, and the highways are packed with single occupancy vehicle traffic.


To address the issue of inadequate transportation services during peak hours for the 4.43 million daily commuters from Seoul to the satellite cities, our team proposed a shared multi-modal ride-hailing service. Specifically, we recommended a van-hailing service that could accommodate up to 15 passengers per vehicle. In addition, we proposed a context-based dynamic vehicle matching recommendation system for users, enhancing the overall user experience by providing personalized and convenient transportation options.

UX Research

We conducted 30 user sessions to test the user and driver apps during the UX design phase. We also organized two intensive mobility service strategy workshops, with a total of 37 participants including customers and technology experts, to determine the strategic direction of the service that meets both user values and business objectives. Additionally, I led user research and test sessions with 30 users to uncover key user values and service functionalities.

Curabitur mi erat, auctor aliquam sem sit amet, molestie condimentum sem. Duis aliquet vulputate nisl, at condimentum metus lobortis at. Interdum et malesuada fames ac ante ipsum primis in faucibus. Suspendisse aliquam pharetra turpis vitae auctor. Aenean nec leo eget elit feugiat ultricies. Maecenas ac leo non ante mollis accumsan.


The project was a great success, demonstrated by the commercial launch of the Ta-Da service, a shared Van-hailing service, which quickly became the leading ride-hailing service in South Korea with 1.7 million active users. This success led to the creation of a new subsidiary business called "SK Mobility" under SKT.
