An airport hub, a chip capital, and a port giant are modeling what a smart city can be.

Taiwan’s city halls are fast becoming laboratories for digital transformation. The country’s central government has promoted smart development for years, but the most interesting work now happens locally, where municipal leaders are pairing artificial intelligence, IoT networks, and data-driven governance with the practical realities of traffic, pollution, healthcare, and climate change.

The result is a set of distinct urban experiments: some cities focus on making the government itself more agile, others on weaving technology into heavy industry, still others on translating world-class R&D into everyday convenience.

Taoyuan, Hsinchu, and Kaohsiung offer three of the most compelling examples. Each has leveraged its own identity — gateway city, innovation hub, and port powerhouse — to shape a unique smart city path. Together, they show how Taiwan’s diverse regions are turning digital ambition into real services that affect residents and businesses alike.

Through the international gateway

Situated southwest of Taipei, Taoyuan sits at the crossroads of Taiwan’s busiest transport networks and its most powerful technology corridor. It’s the first city visitors see when they land and a production base that drives the island’s industrial output.

That dual identity as international gateway and manufacturing heartland has formed an ambitious push to modernize city governance and make daily life smoother for a fast-growing, youthful population. Local leaders talk less about shiny gadgets and more about solving real pain points — congestion, pollution, service delays — with practical, AI-driven solutions.

“The transformation began with an internal shake-up,” the Taoyuan City Government said in an emailed response to Taiwan Business TOPICS. In 2024, Taoyuan created the Smart Urban-Rural Development Committee, Taiwan’s first cross-department digital transformation office, by merging its research and IT agencies into a single engine for data-driven policy. “The move broke down bureaucratic silos, allowing departments to share data and test new tools together.”

To ensure those tools were used effectively, the city launched the Smart Taoyuan Academy, partnering with private tech companies to train civil servants in AI, data analytics, and digital service design — a recognition that talent is as crucial as hardware.

That groundwork is now visible on the streets. “Taoyuan was the first city in Taiwan to deploy AI-controlled traffic signals tuned to its scooter-dense, mixed-vehicle roads,” the government notes. Engineers used the SUMO (Simulation of Urban MObility) simulation platform, which allows modeling of intermodal traffic systems, to teach the system how to handle two-stage left turns and unpredictable traffic flow, cutting wait times and idling while reducing emissions.

Noise — one of residents’ most common complaints — is being addressed through the Quiet Taoyuan Project, which uses AI cameras linked to the police department’s Patrol 2.0 system to detect illegally modified exhausts. Since mid-2023, noise complaints have fallen by more than a quarter.

Healthcare is also getting smarter. “Taoyuan has expanded lung cancer screening with AI image analysis, speeding diagnoses and improving accuracy while using the data to inform environmental and labor policy,” according to the city government. On a citywide scale, a world-first AI environmental pollution recognition system now scans for exhaust plumes, illegal wastewater discharge, litter, and motorcycle noise in real time, improving air and river quality and sharply cutting citizen complaints.

These efforts are earning global recognition. In 2024 alone, Taoyuan collected 17 smart city awards, including the Global Smart 20 and the Asia-Pacific ICT Application honors, and became the first government agency to capture both champion and runner-up in the Gartner Government Digital Innovation Awards. By August 2025, it had already added 14 more accolades.

Yet rapid digitalization also expands vulnerabilities. Taiwan’s government networks collectively endured an average of 2.4 million cyberattacks a day in 2024, with many targeted at transport, telecoms, and defense systems, and traced to China, according to Reuters. This puts pressure on municipal systems like Taoyuan’s AI traffic control and environmental platforms to harden defenses and segment sensitive data.

Taoyuan’s ambitions stretch well past its own boundaries, as showcased by its leadership of the Taoyuan-Hsinchu-Miaoli “Greater Silicon Valley” plan. Backed by Taiwan’s Executive Yuan, the plan aims to knit together one of Asia’s densest technology and manufacturing belts.

The initiative envisions seamless digital IDs so residents can commute, shop, or study across counties without juggling cards; shared smart traffic data to cut cross-region travel time; and a joint disaster early-warning network linking IoT weather, water, and seismic sensors. Telemedicine pilots aim to extend big-city care to rural areas, while open-data platforms invite citizens to co-create new services. “The plan also includes smart manufacturing demonstration zones to help small and mid-sized factories adopt automation and digital tools, plus shared online education resources to shrink the urban–rural learning gap and grow the region’s next wave of tech talent,” the government told TOPICS.

Looking ahead, Taoyuan plans to push AI deeper into everyday challenges: making crosswalks safer, clearing paths for ambulances, and anticipating environmental risks before they affect residents. “We want the city to stay a testbed for new technology while serving as the connective hub for Taiwan’s emerging Greater Silicon Valley,” the government said.

The tech backbone

Hsinchu has long been the heart of Taiwan’s semiconductor industry, home to the world-famous Hsinchu Science Park and a dense network of engineers, startups, and research institutes. But city leaders want that technological clout to reach beyond factory gates and research labs.

Hsinchu’s smart city push centers on turning cutting-edge R&D into public benefit, making life more convenient and sustainable for residents while boosting the city’s appeal to the highly skilled talent the region relies on.

The effort begins with government modernization. “Hsinchu has been digitizing its city hall, adopting new data systems to streamline administration and improve service delivery,” the Hsinchu City Government told TOPICS in an email. A practical example is the Hsinchu Pass mobile app which lets residents ride buses, park, check out library books, and access other public services with a single digital identity rather than through a physical card. The government says that “for officials, the platform creates a valuable data stream to understand how people move and use resources, which helps fine-tune transit and plan city facilities.”

Mobility has become a priority in a city where commuters rely on everything from scooters to buses to reach jobs in the Science Park and beyond. Hsinchu’s new onboard “six-in-one” intelligent monitoring system combines AI with connected sensors to monitor noise and air pollution and improve the quality of residents’ living environment. Though not a transportation sector initiative, the data helps planners fine-tune signals, anticipate bottlenecks, and keep public transport running more reliably.

This rethinking of movement is part of a broader “healthy smart city” vision. “As the Science Park expands, new districts are being planned with people in mind — walkable, green, and supported by intelligent transit designed in from the start rather than added later,” according to the government.

Hsinchu’s technology ecosystem is deeply involved in this work. Local companies and universities help design and test the AI models, sensors, and data systems that underpin these services. That collaboration lets the city act as a living lab, refining tools at home before they scale more widely. It’s an approach that has produced improvements in everything from traffic management to environmental monitoring, where real-time data helps address air quality and safety concerns faster.

Yet the city is clear-eyed about the challenges of being a tech capital. “The Science Park’s energy demands put pressure on sustainability goals,” the city government noted. Moreover, attracting and retaining global talent requires more than high salaries, and residents expect strong data privacy and transparency as more public services go digital. “Balancing the pace of innovation with public trust is an ongoing priority.”

Another tension is livability. Hsinchu’s prosperity, fueled by its semiconductor prowess, has pushed average household disposable income to NT$1.5 million (US$49,000), the highest in Taiwan for the second straight year, according to data released by the Directorate-General of Budgeting, Accounting and Statistics. That wealth has also driven housing prices and rents sharply upward. Income gaps are widening, too: the city’s top 20% of households now earn more than six times what the bottom 20% bring in.

To be sure, the city’s next phase will hinge on scaling successful pilots and keeping its infrastructure ahead of growth to ensure that everyone, not just the tech elite, benefits from the city’s digital transformation.

The smart southern stronghold

Kaohsiung has long been synonymous with steel, petrochemicals, and one of Asia’s busiest ports. Today, it is proving that it’s possible for an old industrial powerhouse to reinvent itself as a green, data-driven city — and in the process set a benchmark for how technology can tackle the legacies of heavy industry. “We are positioning the city to be the region’s smart hub,” the Kaohsiung City Government told TOPICS in writing.

City officials — acutely aware of this heavy industrial legacy — are frank about the challenge: decades of manufacturing left a carbon-heavy footprint and complex infrastructure. “Our answer has been to twin net-zero ambition with digital transformation, using advanced AI and IoT to clean up the past and future-proof growth,” officials said.

A defining move was the passage of Taiwan’s first Net-Zero City Development Self-Governance Ordinance. Alongside it came a carbon budgeting system, a Net-Zero White Paper, and the Net-Zero Academy to train the talent industry it will need to decarbonize. “The city aims to cut greenhouse gas emissions by 30% by 2030 and reach carbon neutrality by 2050,” officials told TOPICS. But the push is about more than compliance — it’s about securing a competitive future for Kaohsiung’s manufacturers and port operators.

Delivering that goal will be challenging. Kaohsiung’s newly passed carbon budget for 2025-26 targets a reduction of 3.83 million metric tons of greenhouse gases, but much of the city’s emissions come from steelmaking, petrochemicals, and shipping, sectors where abatement is costly and often outside direct municipal control, Taipei Times reported in June. How the city turns its budget into measurable cuts in these hard-to-decarbonize industries will be a key test.

Technology is central to that transformation, complementing the city’s passage of Taiwan’s first Net Zero Development Ordinance and related decarbonization plans. The flagship Smart Kaohsiung Lighthouse Project is also building Taiwan’s first sovereign AI platform, a “city governance brain” powered by physics-informed AI, developed with partners like Nvidia and major local tech companies. Unlike generic tools, it’s tailored to Kaohsiung’s needs — from predicting floods to optimizing traffic and supporting healthcare — with the goal of giving civil servants a daily AI assistant able to scan citywide camera feeds and recommend quick, data-driven responses.

“The platform is in the form of a constantly updated virtual model of the city,” officials told TOPICS. It integrates data from infrastructure and disaster-prevention systems, enabling officials to “simulate the impact of typhoons or earthquakes, carry out maintenance before problems escalate, and coordinate rescue operations with far greater precision.”

Residents already feel the shift. Kaohsiung was the first city in Asia to roll out Mobility as a Service (MaaS). Its MeNGo app blends MRT, buses, light rail, shared mobility, and parking into one route-planning and payment platform — even showing personal carbon savings. By utilizing the new-generation intelligent transportation platform, in 2023, when multiple mega concerts and festivals drew more than 200,000 people to the city in a single day, this system helped clear crowds smoothly and quickly.

In the realm of healthcare, the city’s Kaohsiung Healthcare 4.0 Co-Care Cloud connects wearable devices and AI-driven health advice with local clinics to offer real-time, personalized care, especially for older residents. Farmers benefit from the Agrinfo platform, which pushes tailored weather, crop, and market updates via LINE and video, helping protect yields in a changing climate.

“Public safety is being reimagined with similar ambition,” the city said. “Drones and ground robots now enter hazardous fire scenes to stream thermal images and gas data back to command centers.” Additionally, AI keeps a constant eye on traffic speeds and incidents to reduce accidents. And a smart anti-drug platform (the Big Data and 5G AIoT Smart System for Drug Abuse Prevention and Counseling) quietly crunches big data to map risk factors and family networks, flagging hidden hotspots so social services and police can intervene early instead of reacting after harm is done.

Perhaps most striking is how Kaohsiung has turned its urban fabric into a real-world testing ground. The Asia New Bay Area has become Taiwan’s largest 5G AIoT demonstration zone, where startups and global tech players trial next-generation transport, manufacturing, healthcare, and immersive tech. In addition, the Kaohsiung City Government is collaborating with Foxconn to plan comprehensive smart city solutions, using the smart city platform with CityGPT as a foundaiton to accelerate the construction of urban digitalization and intelligent services.

This “test here, then scale globally” model is attracting investment from chipmakers, software developers, and AI firms, creating a local supply chain that runs from computing power to finished applications.

“Kaohsiung also thinks beyond its borders by leading the Southern Taiwan Semiconductor S Corridor and partnering with the central government on the Asia New Bay Area innovation cluster,” the city said. Officials emphasize that for TSMC, the three essentials are land, water, and electricity, and Kaohsiung has worked to clear hurdles on all fronts, particularly in securing water. Alongside the existing Fongshan and Linhai reclamation plants, the city is building the new Qiaotou facility to supply recycled “green water” to industry.

The payoff is already visible: TSMC’s Kaohsiung site has successfully trial-produced 2-nanometer chips ahead of schedule, with mass production slated for the second half of this year. The Kaohsiung City Government has also signed MOUs with other major ports from Poland to the United States. In addition, the city is active in the International Council for Local Environmental Initiatives’ (ICLEI’s) climate-smart network and hosts the southern edition of the Smart City Summit & Expo, “drawing global city leaders and tech companies to exchange solutions and strike partnerships.”
