Understanding the relationship between informal public transport and economic vulnerability in Dar es Salaam

Curated on Posted on by Stefaan Verhulst

WhereIsMyTransport Case Study: “In most African cities, formal public transport—such as government-run or funded bus and rail networks—has limited coverage and fails to meet overall mobility demand. As African cities grow and densify, planners are questioning whether these networks can serve the economically vulnerable communities who benefit most from public transport access to opportunities and services.

In the absence of formal public transport or private vehicles, low-income commuters have long relied on informal public transport—think tro tros in Accra, boda bodas in Kampala, danfos in Lagos—to meet their mobility needs. Yet there is little reliable data on the relationship between informal public transport and economic vulnerability in and around Africa’s cities, making it challenging to understand:

  • Which communities are the most vulnerable?
  • What opportunities and services do people typically attempt to access?
  • What routes do informal public transport operators follow?
  • What are the occupation and gender-related impacts?

Addressing these questions benefits from combining data assets. For example, pairing data on informal public transport coverage with data on the socioeconomic characteristics of the communities that rely on this type of transport…(More)”.

Data for Environmentally Sustainable and Inclusive Urban Mobility

Curated on Posted on by Stefaan Verhulst

Report by Anusha Chitturi and Robert Puentes: “Data on passenger movements, vehicle fleets, fare payments, and transportation infrastructure has immense potential to inform cities to better plan, regulate, and enforce their urban mobility systems. This report specifically examines the opportunities that exist for U.S. cities to use mobility data – made available through adoption of new mobility services and data-based technologies – to improve transportation’s environmental sustainability, accessibility, and equity. Cities are advancing transportation sustainability in several ways, including making trips more efficient, minimizing the use of single-occupancy vehicles, prioritizing sustainable modes of transport, and enabling a transition to zero and low-emission fuels. They are improving accessibility and equity by planning for and offering a range of transportation services that serve all people, irrespective of their physical abilities, economic power, and geographic location.
Data sharing is an important instrument for furthering these mobility outcomes. Ridership data from ride-hailing companies, for example, can inform cities about whether they are replacing sustainable transport trips, resulting in an increase in congestion and emissions; such data can further be used for designing targeted emission-reduction programs such as a congestion fee program, or for planning high-quality sustainable transport services to reduce car trips. Similarly, mobility data can be used to plan on-demand services in certain transit-poor neighborhoods, where fixed transit services don’t make financial sense due to low urban densities. Sharing mobility data, however, often comes with certain risks,..(More)”.

Can Mobility of Care Be Identified From Transit Fare Card Data? A Case Study In Washington D.C.

Curated on Posted on by Stefaan Verhulst

Paper by Daniela Shuman, et al: “Studies in the literature have found significant differences in travel behavior by gender on public transit that are largely attributable to household and care responsibilities falling disproportionately on women. While the majority of studies have relied on survey and qualitative data to assess “mobility of care”, we propose a novel data-driven workflow utilizing transit fare card transactions, name-based gender inference, and geospatial analysis to identify mobility of care trip making. We find that the share of women travelers trip-chaining in the direct vicinity of mobility of care places of interest is 10% – 15% higher than men….(More)”.

Building scenarios for urban mobility in 2030: The combination of cross-impact balance analysis with participatory stakeholder workshops

Curated on Posted on by Stefaan Verhulst

Paper by Sara Tori, Geert te Boveldt, Imre Keseru: “In recent years, scenarios have been increasingly used as a tool for helping decision makers deal with uncertainty, assess risks, enhance policy performance, expand creativity, and stimulate open discussion. In transport, scenario planning is an established method to help solve the mobility challenges of cities. In this paper, we propose a mixed-methods approach that combines cross-impact balance analysis with creative scenario planning workshops. CIB analysis was used to obtain raw scenarios that were enhanced with the output from creative workshops to obtain narratives and visuals to make the scenarios easily communicable. The approach was applied in five cities simultaneously. For each city, we developed three different scenarios for urban mobility by 2030. We found that developing the cross-impact matrix centrally and then adapting it to each city’s local context can significantly reduce the time needed for the analysis. In addition, the methodology employed can easily be adapted to the needs of local stakeholders. As it is a mix of quantitative and qualitative methods, it is easily understandable for stakeholders, allowing them to fully participate in the process. The creative outputs in the form of narratives and images have helped to create results that are easy to communicate with the stakeholders…(More)”.

Using the future wheel methodology to assess the impact of open science in the transport sector

Curated on Posted on by Stefaan Verhulst

Paper by Anja Fleten Nielsen et al: “Open Science enhances information sharing and makes scientific results of transport research more transparent and accessible at all levels and to everyone allowing integrity and reproducibility. However, what future impacts will Open Science have on the societal, environmental and economic development within the transport sector? Using the Future Wheel methodology, we conducted a workshop with transport experts from both industry and academia to answer this question. The main findings of this study point in the direction of previous studies in other fields, in terms of increased innovation, increased efficiency, economic savings, more equality, and increased participation of citizens. In addition, we found several potential transport specific impacts: lower emission, faster travel times, improved traffic safety, increased awareness for transport policies, artificial intelligence improving mobility services. Several potential negative outcomes of Open Science were also identified by the expert group: job loss, new types of risks, increased cost, increased conflicts, time delays, increased inequality and increased energy consumption. If we know the negative outcomes it is much easier to put in place strategies that are sustainable for a broader stakeholder group, which also increase the probability of taking advantage of all the positive impacts of Open Science…(More)”

Virtual Public Involvement: Lessons from the COVID-19 Pandemic

Curated on Posted on by Stefaan Verhulst

Report by the National Academies: “During the COVID-19 pandemic, transportation agencies’ most used public-engagement tools were virtual public meetings, social media, dedicated project websites or webpages, email blasts, and electronic surveys. As the pandemic subsides, virtual and hybrid models continue to provide opportunities and challenges.

The TRB National Cooperative Highway Research Program’s NCHRP Web-Only Document 349: Virtual Public Involvement: Lessons from the COVID-19 Pandemic discusses gaps that need to be addressed so that transportation agencies can better use virtual tools and techniques to facilitate two-way communication with the public…(More)”.

Improving Access and Management of Public Transit ITS Data

Curated on Posted on by Stefaan Verhulst

Report by the National Academies: “With the proliferation of automated vehicle location (AVL), automated passenger counters (APCs), and automated fare collection (AFC), transit agencies are collecting increasingly granular data on service performance, ridership, customer behavior, and financial recovery. While granular intelligent transportation systems (ITS) data can meaningfully improve transit decision-making, transit agencies face many challenges in accessing, validating, storing, and analyzing these data sets. These challenges are made more difficult in that the tools for managing and analyzing transit ITS data generally cannot, at this point, be shared across transit agencies because of variation in data collection systems and data formats. Multiple vendors provide ITS hardware and software, and data formats vary by vendor. Moreover, agencies may employ a patchwork of ITS that has been acquired and modified over time, leading to further consistency challenges.
Standardization of data structures and tools can help address these challenges. Not only can standardization streamline data transfer, validation, and database structuring, it encourages the development of analysis tools that can be used across transit agencies, as has been the case with route and schedule data, standardized in the General Transit Feed Specification (GTFS) format..(More)”.

AI-powered cameras to enforce bus lanes

Curated on Posted on by Stefaan Verhulst

Article by Chris Teale: “New York’s Metropolitan Transportation Authority will use an automated camera system to ensure bus lanes in New York City are free from illegally parked vehicles.

The MTA is partnering with Hayden AI to deploy Automated Bus Lane Enforcement camera systems to 300 buses, which will be mounted on the interior of the windshield and powered by artificial intelligence. The agency has the option to add the cameras to 200 more buses if it chooses.

Chris Carson, Hayden AI’s CEO and co-founder, said when the cameras detect an encroachment on a bus lane, they use real-time automated license plate recognition and edge computing to compile a packet of evidence that includes the time, date and location of the offense, as well as a brief video that shows the violator’s license plate. 

That information is encrypted and sent securely to the cloud, where MTA officials can access and analyze it for violations. If there is no encroachment on a bus lane, the cameras do not record anything…

An MTA spokesperson said the agency will also use data from the system to identify locations that have the highest instances of vehicles blocking bus lanes. New York City has 140 miles of bus lanes and has plans to build 150 more miles in the next four years, but congestion and lane violations from other road users slows the speed of the buses. The city already uses cameras and police patrols to attempt to enforce proper bus lane use…(More)”.

Efficient and stable data-sharing in a public transit oligopoly as a coopetitive game

Curated on Posted on by Stefaan Verhulst

Paper by Qi Liu and Joseph Y.J. Chow: “In this study, various forms of data sharing are axiomatized. A new way of studying coopetition, especially data-sharing coopetition, is proposed. The problem of the Bayesian game with signal dependence on actions is observed; and a method to handle such dependence is proposed. We focus on fixed-route transit service markets. A discrete model is first presented to analyze the data-sharing coopetition of an oligopolistic transit market when an externality effect exists. Given a fixed data sharing structure, a Bayesian game is used to capture the competition under uncertainty while a coalition formation model is used to determine the stable data-sharing decisions. A new method of composite coalition is proposed to study efficient markets. An alternative continuous model is proposed to handle large networks using simulation. We apply these models to various types of networks. Test results show that perfect information may lead to perfect selfishness. Sharing more data does not necessarily improve transit service for all groups, at least if transit operators remain non-cooperative. Service complementarity does not necessarily guarantee a grand data-sharing coalition. These results can provide insights on policy-making, like whether city authorities should enforce compulsory data-sharing along with cooperation between operators or setup a voluntary data-sharing platform…(More)”.

Parallel Worlds: Revealing the Inequity of Access to Urban Spaces in Mexico City Through Mobility Data

Curated on Posted on by Stefaan Verhulst

Paper by Emmanuel Letouzé et al: “The near-ubiquitous use of mobile devices generates mobility data that can paint pictures of urban behavior at unprecedented levels of granularity and complexity. In the current period of intense sociopolitical polarization, mobility data can help reveal which urban spaces serve to attenuate or accentuate socioeconomic divides. If urban spaces served to bridge class divides, people from different socioeconomic groups would be prone to mingle in areas further removed from their homes, creating opportunities for sharing experiences in the physical world. In an opposing scenario, people would remain among neighbors and peers, creating “local urban bubbles” that reflect and reinforce social inequities and their adverse effects on social mixity, cohesion, and trust. These questions are especially salient in cities with high levels of socioeconomic inequality, such as Mexico City.

Building on a joint research project between Data-Pop Alliance and Oxfam Mexico titled “Mundos Paralelos” [Parallel Worlds], this paper leverages privacy-preserving mobility data to unveil the unequal use and appropriation of urban spaces by the inhabitants of Mexico City. This joint research harnesses a year (2018–2019) of anonymized mobility data to perform mobility and behavioral analysis of specific groups at high spatial resolution. Its main findings suggest that Mexico City is a spatially fragmented, even segregated city: although distinct socioeconomic groups do meet in certain spaces, a pattern emerges where certain points of interest are exclusive to the high- and low-income groups analyzed in this paper. The results demonstrate that spatial inequality in Mexico City is marked by unequal access to government services and cultural sites, which translates into unequal experiences of urban life and biased access to the city. The paper concludes with a series of public policy recommendations to foster a more equitable and inclusive appropriation of public space…(More)”.
