“…The investment in transport infrastructure has been increasing with the development of the urban economy. The equity impact of transport infrastructure projects is the basis to ensure equitable urban transportation [29]. Steven et al analyzed the social equity impacts on social groups when public transit ticket pricing structures shifted from flat fare pricing to distance-based fares [30].…”

Measurement and Spatial Differentiation Characteristics of Transit Equity: A Case Study of Guangzhou, China

Urban public transit is an important solution for narrowing the mobility gap between captive riders and choice riders and to address issues of social equity. An equitable transit system essentially could meet the needs of transit dependents and maximize the scope of public transit services. To acquire a better understanding of transit equity, we use Lorenz curves and the GINI coefficient to measure the relative supply of public transit to the population and employ the spatial overlay method to analyze the matching degree of transit supply and demand in Guangzhou, China. The findings show that there are obvious and unequal differences between the levels of transit service in the internal zones. The spatial coverage rate and number of stop services of the outer city are significantly less than that of the inner and middle city. Eighty percent of the population shares only 36.7% of the public transit supply in Guangzhou. Most communities of low-supply and high-need public transit are distributed contiguously in the eastern Baiyun and southern Huadu districts. This distribution pattern is beneficial to the transit agency, which could improve the supply in these areas to avoid the risk caused when a large number of residents lack access to public transit services. The results could serve as an excellent foundation for planning the handling of spatial gaps in the Guangzhou public transit supply.

“…They compared transportation need with public transport access, in order to identify transportation-disadvantaged areas. Delmelle and Casas [10] evaluated the spatial equity of bus rapid transit-based accessibility patterns in Cali, Colombia. They studied accessibility from two aspects, including accessibility to stops and stations and accessibility to activity opportunities.…”

Uncovering Spatial Inequality in Taxi Services in the Context of a Subsidy War among E-Hailing Apps

Spatial inequalities in urban public transportation are a major concern in many countries but little of this research has focused specifically on taxi services. The taxi situation has grown more complex, as traditional ride-for-hire services face growing competition from e-hailing apps like Uber in the U.S., or Didi and Kuaidi in China. In 2014, Didi and Kuaidi triggered a nationwide subsidy war, with possible effects on the spatial inequality of taxi services. Taxi trajectory data from Shenzhen collected during the subsidy war shows that this competition reduced spatial inequality in the inner city but aggravated it in the outer city. In this study, a measure of service rate to depict the quantity of taxi services is proposed to calculate a Gini coefficient for evaluating change in the spatial inequality of taxi services. The Theil index and its decomposition were used to distinguish the contribution of Traffic Analysis Zones (TAZs) in the inner and the outer city and compare them to the overall spatial inequality of taxi services in Shenzhen, TAZs in the outer city had greater inequality in taxi services than the inner city. Furthermore, the primary contributor to overall inequality in taxi services was inequality within, rather than between, the inner and outer city. Moreover, the mean values for the changed service rates in the inner city were always larger than the outer city, and the inner city had a more equitable changed service rate than the outer city. These results could serve as a foundation for improving taxi services citywide.

“…For this reason, pending for future investigation is the determination of both resident and tourist populations with a profile of greater predisposition to use public transport in the examined tourist destination (Cambrils). It will then be necessary to analyse the social equity and efficiency of the public transport structure to meet their mobility needs, as Delmelle and Casas [19] Cardozo et al [20] or Ruiz et al [54]. To develop this approach additional information will be needed on tourist profiles, which means that other sources (e.g., tourist surveys) will be required as current sources used here allowed us to determine the spatial distribution of accommodation for tourists, but provided no data on their profile.…”

“…The results show that the use of public transport is substantially higher in areas with a higher rate of accessibility. Delmelle and Casas [19] evaluated the spatial equity of the express bus transport service in the city of Cali (Colombia) by means of exploration patterns of accessibility in relation to the socioeconomic level of the city neighbourhoods. They demonstrated that transport network accessibility was higher for middle-class neighbourhoods than for those of higher and lower socioeconomic classes.…”

This article develops a methodology for evaluating the effectiveness and spatial coverage of public transport in tourist cities. The proposed methodology is applied and validated in Cambrils municipality, in the central part of the Costa Daurada in Catalonia, a coastal destination characterised by the concentration of tourism flows during summer. The application of GIS spatial analysis tools allows for the development of a system of territorial indicators that spatially correlate the public transport network and the distribution of the population. The main novelty of our work is that this analysis not only includes the registered resident population, but also incorporates the population that temporarily inhabits the municipality (tourists). The results of the study firstly permit the detection of unequal spatial accessibility and coverage in terms of public transport in the municipality, with significant differences between central neighbourhoods and peripheral urban areas of lower population density. Secondly, they allow observation of how the degree of public transport coverage differs significantly in areas with a higher concentration of tourist accommodation establishments.
