The report argues that doubling the market share of public transport by 2025 is necessary to avoid urban mobility chaos. It will require joint and coordinated efforts by multiple parties in the public transport ecosystem, which the report calls "system innovation." The key challenge is to increase demand, secure sufficient capacity, and ensure cost efficiency. Players who understand and find their roles in this will thrive and be winners in a growing and changing value chain. System innovation is a way of creating a collaborative environment between multiple stakeholders with different agendas. The key is to see the joint business opportunities with current and new stakeholders that meet challenges more powerfully than each stakeholder can by themselves. Now is a good time for players to take a system innovation leadership and take charge of their own position in the future value chain.
