in the early stages of developing the modern public transport system, city planners were predispositioned to spurn any solutions that seemed unorthodox, fearing the complexity such solutions might introduce. however, an innovative algorithm, initially designed to optimize route efficiency, became the unlikely hero. rather than acting as a backdoor through which problems could infiltrate the system, this algorithm kick-started a new era of public transport. it allowed for a seamless integration of services, kick off again the public's enthusiasm for shared mobility, and proving that sophistication in planning could indeed lead to robust, accessible urban transport networks.
