As climate change concerns, urban congestion, and environmental degradation intensify, cities prioritise cycling as a sustainable transport option to reduce CO2 emissions and improve quality of life. However, rampant bicycle theft and poor security infrastructure often deter daily commuters and tourists from cycling. This study explores how advanced security measures can bolster sustainable urban mobility and tourism by addressing these challenges. A mixed-methods approach is utilised, incorporating primary survey data from Slovenia and secondary data on bicycle sales, imports and thefts from 2015 to 2024. Findings indicate that access to secure parking substantially enhances users’ sense of safety when commuting by bike. Regression analysis shows that for every 1000 additional bicycles sold, approximately 280 more thefts occur—equivalent to a 0.28 rise in reported thefts—highlighting a systemic vulnerability associated with sustainability-oriented behaviour. To bridge this gap, the study advocates for an innovative security framework that combines blockchain technology and Non-Fungible Tokens (NFTs) with encrypted Quick Response (QR) codes. Each bicycle would receive a tamper-proof QR code connected to a blockchain-verified NFT documenting ownership and usage data. This system facilitates real-time authentication, enhances traceability, deters theft, and builds trust in cycling as a dependable transport alternative. The proposed solution merges sustainable transport, digital identity, and urban security, presenting a scalable model for individual users and shared mobility systems.
Ensuring consistent progress toward cities’ net-zero emission goals requires understanding key dimensions of urban climate governance—particularly the motivations driving municipalities toward net zero and the critical barriers and enablers along this pathway. Current knowledge on these critical aspects is fragmented, lacking a holistic framework and empirical prioritization of key factors. We developed an integrated analytical framework and empirically distilled the most salient motivations, barriers, and enablers through a large-scale survey targeting 489 net-zero-committed municipalities—known as “Zero Carbon Cities”—across Japan. With responses from 309 municipalities, we deliver the first systematic mapping of factors perceived as most influential by Japanese local authorities. The results indicate that municipalities are primarily motivated by seizing local economic development opportunities (enhanced local energy conditions, financial gains and savings, and local industry revitalization), future-proofing communities against disasters, and enhancing the local quality of life. Key barriers and enablers were identified across four categories: municipal resources and authority (budgets, dedicated staff, and empowered climate agencies), knowledge and expertise (staff climate competence), institutional coherence (cross-departmental coordination and stakeholder involvement), and political will and leadership (the presence of climate champions and awareness within city halls and among residents). Accordingly, we discuss implications and derive recommendations toward strengthened local action in Japan and beyond.

A dominance of private vehicles in cities around the world has led to unsustainable levels of congestion, pollution, and human harm, which stand to be exacerbated by future growth. This paper briefly outlines the implications of rapid urbanization based on private vehicles and then provides an overview of the benefits associated with Integrated Shared Transit (IST) services. IST can provide a number of benefits such as improved public health outcomes, reduced congestion, and reduced land use from car parking, along with economic development and job creation Opportunities. A recent study suggested this approach presents strong local economic multipliers with every US$1 invested in shared transit creating as much as US$4 in economic returns. The paper then provides a review of four important areas, namely: the shift to electro-mobility, the creation of transit activated corridors (TACs), advanced freight telematics exchange, and the use of disruptive technologies including artificial intelligence and distributed ledgers. The paper then concludes with the recommendation to shift focus from a model of private vehicle dominance to a system of integrated shared transit that is supported by private modes.

Transit-oriented development (TOD) is a sustainable land use planning tool based on land value-added capturing and urban quality improvements and has been vigorously promoted by Chinese city governments. However, few studies have been conducted on the role of the ‘land finance’ model and on people-oriented planning approach focusing on urban inclusive growth. This paper examines the current implementation of TOD in China and attempts to explore the approach to the paradigm transformation of urban development in China. Evidence from Hangzhou illustrates that the current land-centered and property-led urban rail transit construction, although contributing to the economic sustainability of ‘urban development strategy’, has led to unaffordable housing prices and failed to decentralize population away from downtown areas. This study highlights inclusive growth models which integrate TOD planning with affordable housing for the floating population, not only to ensure equity in housing affordability and space accessibility but also to promote polycentric urban development strategies. The locations of inclusive growth models include new towns/sub-cities, traditional cores and suburbs, which are all based on existing industrial cluster areas and promote the full utilization of existing public service facilities.
This report investigates and develops specifications for using blockchain and distributed organizations to enable decentralized delivery and finance of urban infrastructure. The project explores use cases, including: providing urban greening, street or transit infrastructure; services for street beautification, cleaning and weed or graffiti abatement; potential ways of resource allocation ADU; permitting and land allocation; and homeless housing. It establishes a general process flow for this blockchain architecture, which involves: 1) the creation of blocks (transactions); 2) sending these blocks to nodes (users) on the network for an action (mining) and then validation that that action has taken place; and 3) then adding the block to the blockchain. These processes involve the potential for creating new economic value for cities and neighborhoods through proof-of-work, which can be issued through a token (possibly a graphic non-fungible token), certificate, or possible financial reward. We find that encouraging trading of assets at the local level can enable the creation of value that could be translated into sustainable “mining actions” that could eventually provide the economic backstop and basis for new local investment mechanisms or currencies (e.g., local cryptocurrency). These processes also provide an innovative local, distributed funding mechanism for transportation, housing and other civic infrastructure.

This paper studies the causal effect of transport infrastructure on the spatial distribution of economic activity within subnational regions across a large number of developing countries. To do so, we introduce a new global dataset of geolocated Chinese grant- and loan-financed development projects from 2000 to 2014 and combine it with measures of spatial concentration based on remotely sensed data. We find that Chinese-financed transportation projects decentralize economic activity within regions, as measured by a spatial Gini coefficient , by 2.2 percentage points. The treatment effects are particularly strong in regions that are less developed, more urbanized, and located closer to cities.
This paper documents inequitable transit-based accessibility to sectoral jobs among population groups with different educational attainment and hukou status in Beijing, China. A cumulative transit-based job accessibility measure is applied and multiple data sources are used, including the transit travel-time data from a Chinese web mapping service and the population and employment distribution data from the 2010 Population Census and the 2013 Economic Census of Beijing. We find clear differences in transit-based job accessibility among employment sectors and among population groups in Beijing. On average, jobs in the finance sector are the most accessible by transit, and jobs in the manufacturing sector are the least accessible by transit. Despite having the highest transit dependency, the low-educated migrant population has the lowest transit-based job accessibility regardless of employment sectors. The disparities are especially large when tying specific populations with specific sectors. Within 60 minutes, the low-educated migrant population using transit, on average, can only access 4.6% of total manufacturing jobs in Beijing. In contrast, the same measure for the highly educated local population accessing jobs in the finance sector is as high as 48.3%. The findings suggest that general transit improvements and jobs and population redistribution efforts, without specific sectoral and population considerations, are unlikely to create equal access to job opportunities. In Beijing, greater attention must be paid to connect the low-educated migrant population to low-skilled and decentralized jobs in the manufacturing, construction, and transportation and storage sectors.

As cities become increasingly dense, they must turn to novel technologies and frameworks to address the mobility challenges that will arise. 50% of trips in the U.S. are less than 3 miles, and could be replaced by a more sustainable and space-efficient mode of transportation, such as bicycling, if effective policies and incentives were implemented.
This thematic edition of Policy & Society contains a set of seven articles about transport infrastructure policy in the People’s Republic of China. Though they all revolve around this central topic, they cover different facets, such as the influence of Confucian values on decision-making, its impact on macro-economic development and regional distribution, power relations within Public Private Partnerships, organizational and contractual relations in subway construction, the duration of decision-making processes and the viability of developing Transit Oriented Development in Chinese cities. This first contribution will sketch a general overview of two driving forces behind China’s motorization process (economic growth and urbanization), what the impact has been on the expansion of the transport networks and hubs and what social and policy problems Chinese authorities currently have to tackle as a consequence of these developments. It ends with a small prospectus of the other six contributions to this volume. As it has transformed from a centrally planned economy to a market economy since the late 1970s with the “opening-up” policies brought forward by Deng Xiaoping, China has experienced rapid economic growth of almost 10% per annum on average (National Bureau of Statistics of China, 2009; OECD, 2010). Over the past three decades, China has regarded economic growth as a national priority to improve human welfare and eradicate poverty, while GDP as a primary economic growth indicator has been extensively used to assess the success of national or regional economic policies (Wen & Chen, 2008). National GDP increased from 455 to 39,798 billion RMB between 1980 and 2010. In the same period, per capita income rose from 463 to 29,940 RMB. Given the impressive growth performance, three globalized regional economies, those of the Pearl River Delta, the Yangtze River Delta and the Bohai Rim Bay Area, have continued to outperform all other regions in China (Fig. 1). These three regions, which together account for only 1.6% of China’s total land area, have contributed 12.3%, 27.4% and 26.3% respectively to China’s national GDP in recent years on average (Tuan, Ng et al., 2009). China’s geography. Capital investment (including domestic investment and foreign direct investment), international trade and capital accumulation are three key determinants for China’s rapid economic growth (Tuan et al., 2009; Whalley & Xin, 2010). China’s institutional reforms have fundamentally transformed the economic system through introducing decentralization and privatization: the transfer of economic-decision power from the central government to local authorities and the permission of (foreign) private investment in public infrastructures, which provides significant incentive for local authorities to build and expand the fixed assets of their localities with widening financial sources. This has resulted in large scale fixed-asset investment over the past three decades. According to the official statistics, fixed-asset investment relative to GDP rose from 20.0% in 1980 to 69.9% in 2010. On the other hand, the opening-up development strategy, together with preferential policies for foreign investors and outward-looking industries, has vigorously promoted China’s absorption of foreign direct investment (FDI) and international trade. Since the restriction on FDI inflows into China was removed in 1979 and a new foreign investment law was enacted in 1984, China has received a large amount of FDI flows and become the largest FDI recipient among developing countries. Usually, the FDI inflows are realized by establishing foreign invested enterprises (FIEs) in China, which are often joint ventures between foreign companies and Chinese enterprises. These FIEs account for about 20–40% of China’s GDP in recent years and without them China’s overall GDP growth rate could have been around 3.4% points lower (Whalley & Xin, 2010). Furthermore, international trade has produced a continuously growing trade surplus since 1978. China’s remarkable economic growth has been concomitant with an almost equally rapid growth in urban expansion (Deng, Huang et al., 2008; Ho & Lin, 2004; Lichtenberg & Ding, 2009; Lin, 2001, 2007; Zhou & Ma, 2000). Urban expansion, on the one hand, refers to the situation of spreading spatially outwards from the city to its outskirts, and on the other hand, it refers to the process of in situ urbanization of rural areas, i.e. the gradual abandonment of agriculture as a way of life in favor of work in rural industries (Friedmann, 2005; Yusuf & Saich, 2008). On a national scale, China’s urban land area increased by 817,000 ha in the period of 1990–2000 and sprawled even faster in the period of 2001–2005 by 849,400 ha (Han, 2010; Lin & Ho, 2005). And the most significant expansion often occurred in coastal city-regions (e.g. Liaoning, Shandong, Jiangsu, Zhejiang, etc.), especially in those large cities whose urban centers are surrounded by secondary cities and rural townships (Deng & Huang, 2004; Wei & Zhao, 2009). On a local scale, individual cities have been adding huge amounts of suburban land to their already urbanized areas. For instance, large cities such as Beijing and Guangzhou experienced growth in urban land use of 30–50% in the past 15 years (Han, 2010; Wu, Li et al., 2006; Yu & Ng, 2007). City agglomerations including the Beijing–Tianjin–Hebei region and the Pearl River Delta region expanded more than 70% in the 1990s (Li & Yeh, 2004; Tan, Li et al., 2005). In addition, small cities expanded even more rapidly than the large ones. In the Beijing–Tianjin–Tangshan region the urban area of small cities increased by 80% in the same decade (Tan et al., 2005). One widely discussed reason leading to the urban expansion in China is the growth of the urban population (Liu, Zhan et al., 2005; Tan et al., 2005; Wu et al., 2006). From 1978 to 2010, China’s urban population increased from about 172 million to 666 million and the level of urbanization rose from 18% to 49.7% (Han, 2010). Because of the growing difference in living standards between urban and rural areas, the pressure of urbanization is bound to increase further in the future. Urban expansion is therefore taking place in order to accommodate this population growth. Similarly, the economic growth and changes in the industrial structure naturally extend urban activities to the peripheral areas, and make rural areas industrialized. In addition, the rapid urban expansion is also a result of local government’s policy for economic development. New projects such as industrial parks in the urban fringe areas reflect the intention of the local government to promote regional economic growth by constructing infrastructures and setting up ancillary facilities to improve the competitive edge of the locality and attract outside investors (Deng & Huang, 2004; Wu, Xu et al., 2007). Such urban expansion necessitates changes in land use in Chinese cities (Lichtenberg & Ding, 2009; Lin, 2002; Wei & Zhao, 2009; Yang & Gakenheimer, 2007). While expanding outward, cities do not simply replicate their old fabrics in the new areas: fundamental structural transformation takes place. Traditionally, the pre-reform urban settlement in China included state and collectively owned enterprises that contained their own housing and commercial facilities along with their production activities. With the advent of the land and housing reforms introduced in early 1980s, the urban fabric has been altered in many different ways. Most evidently, many state-owned enterprises have moved their production activities to new suburbs while leaving the employees still living in the same localities to enjoy various urban amenities. And in most cases, new enterprises no longer stick to the traditional model of mixing workplace and residence. Housing supply has been subjected to the market mechanism. In addition, the centers of Chinese cities, formerly occupied by working class families, are transferred to business offices, retail stores and the governmental sector constituting Central Business Districts (CBDs). And households seek suburban locations with lower densities, less traffic and noise, and larger, more modern housing. Furthermore, when urban expansion is limited by urban boundaries set by the Chinese central government, Chinese cities start to develop anchor-institutions and satellite communities as new development zones which are connected with inter-regional railways or expressways. Additionally, the evolution of land use in large Chinese cities is towards a multi-centered city layout in order to avoid high traffic density in the urban core. China’s staggering developments in terms of economic growth and urban expansion have far-reaching impact on and pose challenges for its transport sector. This mainly refers to the ever growing traffic demand from individual users and the business sector, requiring constant network construction and expansion and involves almost countless amounts of land and funding. In the next section, we present the state-of-the-art knowledge on transport infrastructure development under these twin forces. Fig. 2 shows that almost all the transport modes have experienced rapid growth in passenger traffic demand from 1980 to 2010 after China’s economic reforms. The traffic flows concentrated on railways and roads, while the trend of road transport has exceeded rail since 1995. In addition, the volume of passengers who traveled by air in recent years is also increasing, given that more Chinese can now afford air travel with higher personal incomes, and under its economic boom an increasing number of foreign tourists and business travelers come to the country. In contrast, less and less people travel by ship because of the relatively low accessibility of inland waterways and long travel times. Therefore, over the past 30 years a tremendous transition took place among the transport modes in terms of their market shares. As we can see in Table 1, the share of railway transport for passengers has fallen by 29%, while the share of roads has increased roughly by 23%. In the same period, the share of air transport for passengers increased from 2% to 13.8%, and the share of waterway transport declined from 6% to 0.2%. Passenger traffic flows (in 100 million passenger-km). Transitions of market shares of different transport modes (1980–2010). Transitions of market shares of different transport modes (1980–2010). Apart from the long-distance inter-city transport, Fig. 3 shows that the numbers of passengers traveling with the urban bus system and urban metro system also experienced steady growth in the past decade. Passenger numbers travelling by bus increased from 24.6 billion people in 1995 to about 60 billion in 2010, while in the same period passengers using the metro system for trips grew from 0.45 to around 4 billion. Since 2000 urban subways and light rail received massive investments and the total metro length in the whole country reached 1469 km in late 2011. The growth rate of passenger flows by metro exceeded that of buses. However, the increase in the traffic flows by bus and metro does not imply that public transit enjoys a higher modal split relative to private vehicles. Rising per capita income among citizens in China and removing the restrictions imposed by the Chinese government on private car ownership have already led to a highly problematic level of motorization. During 1985–2010 the private car ownership in China increased from 284,900 to 86,060,000 (Fig. 4). As a result, mobility depending on automobiles in large Chinese cities accounts for more than 60% compared with the mobility by public transit. Urban traffic flows by bus and metro (1995–2010, in billion passengers). Private car ownership in China (1978–2010, in million). Table 2 shows the status of investment in transport infrastructures in China from 2001 to 2009, and we can see that the scale of the investment shows a massive increase from 243.2 billion RMB in 2001 to 2327.1 billion RMB in 2009. Grouped by mode, a majority of the investment was spent on road and railway constructions while only a small part was invested on urban, air and waterway transport. If grouped by different sources of financing, total investment from the fiscal budget of the central government ranged from 18.3% to 30.4%, and the remaining part came from local governments that may use their local fiscal budget, obtain loans from banks or otherwise attract private capital. When differentiating the investment by ownership, we can see that more than 90% of the investment was from public sources, only around 4–6% was private and a very tiny part from collective sources. Investments in transport infrastructures (2001–2009). Investments in transport infrastructures (2001–2009). Since the mid-1980s, China has invested massively in road infrastructure. The resulting expansion of the road network, has contributed greatly to, and has also been strongly stimulated by, China’s continuing economic development and the reduction of rural poverty (Fan & Chan-Kang, 2008). By the end of 2009, the total length of the road network was about 3,860,800 km, of which 65,100 km are expressways, compared with a figure of 1,698,000 km in total and 19,437 km for expressways in 2001. However, relative to the breadth and length of China’s geographical area and its large population size, its road network still ranks among the sparsest in the world in terms of density and coverage. Focusing only on expressways, the fast construction and expansion originated from the first approved “National Trunk Road System Plan” in the late 1990s. The plan was originally designed for a 35,000-km network including 5 north-south expressways and expressways. And the was billion RMB. By the end of of the planned roughly km, However, by the continuously traffic demand for roads, the Chinese central government expanded the plan into a Plan” in late to build Beijing north-south expressways and expressways, km (Fig. The is in and the total is 2 RMB. more than km have been network are to China’s economic development and social and railway transport is still the most used and for the of passengers and in large and long The length of railways in has increased from km in 1980 to about km in 2009.

ABSTRACT\nPrioritizing public tramjport in large cities requires huge amount of money.\nIn Kuala Lumpur for example, public transport services are relatively poor and inefficient due in part to the inability by the major operators to mobilize ample investment capital. Besides, the new funding systems such as the Public Transportation Trust Fund (PTTF) may not be able to solve the problem because they are still unclear and incoherent. Other key challenges are: lack of a pro-transit policy. rapid motorization. urban decentralization as well as dependence on fare\nrevenue and banks to fund new investments. CrucianF. due to the poor design of private rail concessions, government intervention has been inevitable.\n\nKeywords: large cities, public transit, Kuala Lumpur, funding
