This paper addresses these gaps by introducing the first-ever collection of ground truth data on parking search durations gathered through a self-developed app. The dataset encompasses more than 3500 journeys collected in Germany, with approximately two-thirds of them ending in Frankfurt am Main. Utilizing this unique dataset, we developed a deep learning neural network model that accurately identifies parking search routes in GPS data and predicts search duration. Our model outperforms existing parking search identification models proposed in previous studies. The model’s efficacy is further evaluated on an independent park-and-visit dataset and then applied to a large-scale dataset from Frankfurt/Germany. This generates the first reliable statistics on parking search durations and reveals key insights about parking search patterns in this city. Notably, the predicted mean parking search duration from this extensive dataset, comprising over 860,000 journeys, is approximately 1.5 min. This work not only advances the field by providing a new data collection methodology and a superior predictive model but also offers a reusable framework that can be applied to other cities and datasets for broader urban mobility insights.</p></div>","PeriodicalId":100852,"journal":{"name":"Journal of Urban Mobility","volume":"6 ","pages":"Article 100083"},"PeriodicalIF":2.7,"publicationDate":"2024-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S266709172400013X/pdfft?md5=50644b0803e656ccd3c7d1e91411e33a&pid=1-s2.0-S266709172400013X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142011280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this regard we present the \"On demand shared use bike sharing system (OSABS)\" as an eco-friendly on-demand mobility alternative that has the potential to revolutionize transportation from its core. Self-driving bikes provide a solution by reducing traffic congestion and promoting sustainable modes of transport. Customers can easily reserve a bike through their smartphones and it comes directly to their location within the given time. The user will ride it manually and release it after usage. The bike then drives autonomously to the next destination.

However, the steadily rising demand for transporting goods puts cities under pressure. Hence, municipalities strive for alternative solutions for urban freight transport, especially parcel shipments on the first and last mile. Freight demand models are suitable to evaluate the transport-related effects of such solutions. However, developing those models requires a sufficient amount of data, which, to date, especially for establishments, cannot be covered in its necessary scope and accuracy by publicly available sources. Although parcel shipments to and from establishments make up to 40 % of the overall courier, express, and parcel market, these are often neglected in existing modelling approaches. Hence, in this study, we present a data collection concept for generating highly relevant data for the microscopic modelling of urban freight, i.e., parcel transport focusing on establishments. To reflect transport demand (i.e., establishments that need to have goods shipped) and transport supply (i.e., carriers that provide a transport service), a mixed-method approach is developed comprising complementary components. On the one hand, an online establishment survey is designed aiming to reveal disaggregated transport demand data for the subsequent modelling process. The survey focuses on the delivery and shipment characteristics of goods, such as temporal and spatial demand patterns. On the other hand, expert interviews are conceptualized to identify relevant patterns of transport supply carriers such as courier, express, and parcel service providers and shall further work as secondary data for the modelling process. The approach is applied in the region of Karlsruhe, Germany. It can be shown that the survey is generally suitable for generating freight transport data on a disaggregated level and that the mixed-method approach is capable of mutually validating the data obtained. However, our approach also emphasizes the necessity to conduct an establishment survey as a personal rather than a self-reporting interview, even if the costs are higher.</p></div>","PeriodicalId":100852,"journal":{"name":"Journal of Urban Mobility","volume":"6 ","pages":"Article 100085"},"PeriodicalIF":2.7,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667091724000153/pdfft?md5=3aecbf37700aa6de799604b97a1ec318&pid=1-s2.0-S2667091724000153-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141963759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Alongside, sustainability concerns are also accelerating the design of new policies for improving citizens’ quality of life in urban areas. To address this new paradigm, municipalities need to consider new methodologies encompassing the different dimensions of the urban environment.

Against the backdrop of the growth of major German cities over the last few years, the question has become whether and how a change in the modal split in favor of more environmentally and climate-friendly public transport sector can be achieved. The Federal City of Bonn is one of five model cities that is testing measures to reduce traffic-related nitrogen dioxide emissions through a Climate Ticket as a mobility flat rate for one year for 365 €, which is part of the two-year \"Lead City\" project funded by the federal government. A quantitative survey (<em>n</em> = 1,315) of Climate Ticket users as well as the logistic regression carried out confirm that a change in individual mobility behavior in favor of public transport is possible by subsidizing the ticket price. The results show that individual traffic could be saved on the city's main congestion axes. In order to achieve a sustainable improvement in air quality, such a Climate Ticket must be granted on a permanent basis, with a well-designed mobility offer and must be generous in terms of the group of authorized persons and the area of validity.</p></div>","PeriodicalId":100852,"journal":{"name":"Journal of Urban Mobility","volume":"6 ","pages":"Article 100082"},"PeriodicalIF":2.7,"publicationDate":"2024-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667091724000128/pdfft?md5=a9cb0aa29eb18dc1d87c3f96bc847503&pid=1-s2.0-S2667091724000128-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141438234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the growing trend of urbanization and the associated phenomenon of cities’ sprawl being increasingly evident, significant attention should be given to understanding PT systems’ performance and then improving their efficiency. Considering the spatial characteristics of the PT system's performance promotes the environmentally friendly transport “character” that every city endeavors. This paper aims to incorporate the spatial spillover effects of a realistic PT system by augmenting information about the service network along with socio-economic variables, in a spatial demand-supply econometric framework. In detail, geographically separated demand and supply information on bus stops and lines was analyzed by a spatial econometric model, namely, the Spatial Lagged X (SLX) model which may be formatted so that can soundly handle, spatial and –in particular- network data like those coming from the General Transit Feed Specification (GTFS) protocol widely used in PT systems. The novelty and the importance of the proposed model rely on the ability to introduce transit network structure within the framework of spatial econometric regression, fostering the explanatory statistical analysis over networked information. The developed modeling approach was applied to the urban and rural PT system of Nicosia (Cyprus), incorporating the spatial spillover effects of the system over more than 1,500 bus stops, 40 lines, and 252 different but spatially connected postcode areas. The results of the SLX model were compared with other demand models of this form typically used, namely the Ordinary Least Square model and standard Spatial Autoregressive models, providing solid evidence of the benefits of incorporating the network structure in spatial demand modeling, giving valuable input for further planning purposes.</p></div>","PeriodicalId":100852,"journal":{"name":"Journal of Urban Mobility","volume":"6 ","pages":"Article 100081"},"PeriodicalIF":2.7,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667091724000116/pdfft?md5=b352bbdc1a766503e28b6f95038fb519&pid=1-s2.0-S2667091724000116-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141433872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the transport sector, stakeholders are still dealing with and learning from its consequences, as many users have changed their preferences towards private and less sustainable modes. In this paper, a mixed logit modelling approach was applied to a vast database from a stated preference survey conducted in Germany to assess the influence of COVID-19 on mobility preferences in three different stages of the pandemic period: lockdown (high-risk of spread, May 2020), post-lockdown (medium risk of spread, June 2020), and a period where the number of infected cases was lower (small risk of spread, October 2020). Several variables were included in the analysis, such as sociodemographic characteristics, mobility habits and preferences regarding future mobility solutions. Three models were developed, one for each pandemic stage. A comprehensive and reflective analysis of the models’ results, aligned with other studies’ findings, shows that the utility of public transport (PuT) and bicycles, based on individuals’ sociodemographic characteristics and choice attributes, compared to cars was affected by the pandemic state. Regarding the influence of crowding inside PuT during the different periods, it was concluded that users are more willing to pay an extra for their monthly passes to have available seats in PuT in the latter stage of the pandemic. The availability of dedicated bike lanes and a shower at the destination were considered attractive factors for cycling during the lockdown phase. Regarding the private car use, the cost of parking is the only attribute that demonstrates a causal effect on the preference for using this mode. This attribute holds a greater relevance during the post-lockdown and “new normal” periods. The results of this study can be helpful to guide policymakers on the definition of actions to counteract the increasing preference for private transport in the future and during disruptions.</p></div>","PeriodicalId":100852,"journal":{"name":"Journal of Urban Mobility","volume":"5 ","pages":"Article 100079"},"PeriodicalIF":0.0,"publicationDate":"2024-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667091724000098/pdfft?md5=0e71111184dfe8a53f92ca4c93db1621&pid=1-s2.0-S2667091724000098-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141077886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Car-centrism is at the core of this mobility problem. However, government solutions to the traffic problem are overly focused on infrastructure and technological interventions. In this article, we engage with how civil society plays a fundamental role in initiating and sustaining street experiments in constituent cities of Metro Manila and how they influence change in transport governance through utilising the (1) <em>bibingka</em> or sandwich approach and (2) acting as a ‘critical friend.’ We share an example of the <em>bibingka</em> approach through the <em>Bayanihan sa Daan</em> (Collective Heroism in the Road), a road-sharing initiative in the busy streets of the Ortigas business district in Pasig City, Metro Manila. Meanwhile, we present cases of how civil society organisations acted as a critical friend to initiate street experiments and reforms through organisational partnership or appointment of their members to positions in government transport agencies. Through these approaches, we show that civil society participation in initiating street experiments is critical to ensuring that solutions to the traffic problem contribute to the mobility of people rather than of cars. In this vein, we put forward street experiments as fundamental to ensuring just transitions towards realising mobility justice, especially in cities of the Global South.</p></div>","PeriodicalId":100852,"journal":{"name":"Journal of Urban Mobility","volume":"5 ","pages":"Article 100075"},"PeriodicalIF":0.0,"publicationDate":"2024-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667091724000050/pdfft?md5=9630b761b10eb7d0b497d9fb13760171&pid=1-s2.0-S2667091724000050-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140543899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
