What Is a Smart City?
A smart city uses digital technology, data and connected infrastructure to improve the quality and efficiency of urban services. In transport, this means connected traffic management, real-time public transport information, autonomous vehicles, electric mobility infrastructure and integrated mobility platforms that allow residents to plan and pay for journeys across multiple transport modes from a single app.
The Role of Electric Mobility
Electric vehicles are a foundational element of smart city mobility. They produce no local exhaust emissions — improving urban air quality. They are quieter — reducing noise pollution. They can be integrated with smart charging infrastructure that responds to grid signals, renewable energy availability and demand patterns. And they generate data — on usage, routes, energy consumption and charging patterns — that feeds into city-wide mobility management.
Autonomous Vehicles in Smart Cities
Autonomous vehicles — from delivery robots to autonomous buses — are increasingly being deployed in controlled smart city environments. Geofenced zones, defined routes and connected infrastructure enable reliable autonomous operation in urban settings. Applications include autonomous last-mile delivery, campus and airport mobility, autonomous public transport on defined routes, and autonomous maintenance and service vehicles.
- Autonomous last-mile delivery: reducing delivery vehicle traffic in urban centres
- Campus mobility: autonomous shuttles on university, hospital and corporate campuses
- Airport operations: autonomous cargo, catering and maintenance vehicles
- Public transport: autonomous buses on defined routes in controlled environments
- Service vehicles: autonomous cleaning, maintenance and inspection vehicles
Connected Infrastructure
Smart city mobility depends on connected infrastructure — traffic signals that communicate with vehicles, charging points that respond to grid signals, parking systems that guide drivers to available spaces, and data platforms that aggregate information from across the transport network. Vehicle-to-infrastructure (V2I) communication enables traffic signal priority for public transport, emergency vehicles and autonomous vehicles.
Integrated Mobility Platforms
Mobility-as-a-Service (MaaS) platforms integrate multiple transport modes — public transport, ride-sharing, bike-sharing, autonomous vehicles, electric scooters — into a single planning and payment interface. Users can plan a journey that combines a bus, an autonomous shuttle and a shared electric bike, and pay for the entire journey with a single transaction. MaaS platforms reduce private car dependency and improve the efficiency of the overall transport network.
The Role of Data
Data is the nervous system of smart city mobility. Real-time data from vehicles, infrastructure and users enables dynamic traffic management, predictive maintenance, demand-responsive transport and continuous optimisation of the mobility network. Privacy and data governance are important considerations — smart city mobility systems must handle personal data responsibly and transparently.
