These rapid changes have also brought up some new innovative ideas on how to provide efficient and safe transportation services that can leverage emerging technologies. These opportunities can make transportation affordable and equitable with improved mobility options available to all types of travelers.https://ecommons.udayton.edu/stander_posters/2841/thumbnail.jp

MobiSplit: a Scalable Approach to Emerging Mobility Networks

First ACM/IEEE International Workshop on Mobility in the Evolving Internet Architecture. Session: Architectural issues. San Francisco, California, Dec. 01 2006This paper presents a novel architecture, MobiSplit, to manage mobility in future IP based networks. The proposed architecture separates mobility management in two levels, local and global, that are managed in completely independent ways. The paper describes the flexibility advantages that this architecture brings to operators, and how it is appropriate for the current trend to multiple and very different access providers and operators. Heterogeneity, support for seamless handovers and multihoming, and scalability issues are analyzed in the paper

Insider Threats in Emerging Mobility-as-a-Service Scenarios

Mobility as a Service (MaaS) applies the everything-as- \ a-service paradigm of Cloud Computing to transportation: a MaaS \ provider offers to its users the dynamic composition of solutions of \ different travel agencies into a single, consistent interface. \ Traditionally, transits and data on mobility belong to a scattered \ plethora of operators. Thus, we argue that the economic model of \ MaaS is that of federations of providers, each trading its resources to \ coordinate multi-modal solutions for mobility. Such flexibility comes \ with many security and privacy concerns, of which insider threat is \ one of the most prominent. In this paper, we follow a tiered structure \ — from individual operators to markets of federated MaaS providers \ — to classify the potential threats of each tier and propose the \ appropriate countermeasures, in an effort to mitigate the problems

Roaming Real-Time Applications - Mobility Services in IPv6 Networks

Emerging mobility standards within the next generation Internet Protocol, IPv6, promise to continuously operate devices roaming between IP networks. Associated with the paradigm of ubiquitous computing and communication, network technology is on the spot to deliver voice and videoconferencing as a standard internet solution. However, current roaming procedures are too slow, to remain seamless for real-time applications. Multicast mobility still waits for a convincing design. This paper investigates the temporal behaviour of mobile IPv6 with dedicated focus on topological impacts. Extending the hierarchical mobile IPv6 approach we suggest protocol improvements for a continuous handover, which may serve bidirectional multicast communication, as well. Along this line a multicast mobility concept is introduced as a service for clients and sources, as they are of dedicated importance in multipoint conferencing applications. The mechanisms introduced do not rely on assumptions of any specific multicast routing protocol in use.Comment: 15 pages, 5 figure

A Software-Agnostic Agent-based Platform for Modelling Emerging Mobility Systems

Due to the rapidly accelerated innovation cycle in transport and the emergence of new mobility concepts and technologies, public authorities, policy makers, and transport planners are currently in need of the tools for sustainable spatial and transport planning in the new mobility era. In this paper, a new modular, software-agnostic and activity-based spatial and transport planning platform is designed, i.e, the HARMONY Model Suite, that facilitates a novel integration of new and existing spatial and transport modelling tools. The paper focuses on describing the architecture of the platform and its passenger mobility simulation framework, which integrates -in an interoperable manner- activity-based models, mobility service management, and traffic simulation tools for evaluating new mobility system dynamics. The service management controllers for new mobility concepts are discussed in more detail with regards to their functionality and applicability

Understanding Emerging Travel Behavior in New York City

Many large cities face significant challenges in providing safe, economical, equitable, reliable, and efficient mobility services. Moreover, mobility service options have been changing unprecedentedly due to the advent of emerging mobility services. Understanding the impacts of emerging mobility services (e.g., for-hire vehicles, bike sharing) on other travel modes (e.g., transit, non-motorized modes, personal car) and evolving travel behavior is critical to promote sustainable modes for urban residents and reduce auto-dependency. New York City (NYC) has been conducting annual mobility survey since 2017 to understand the emerging travel behavior and mode choice characteristics. This dataset presents a unique opportunity for conducting research on the effects of emerging mobility services and the mode choice behavior of urban residents. This dissertation investigates emerging travel behavior in NYC to promote sustainable mobility and reduce auto-dependency. Three specific research objectives are to- i) identify factors that influence the choice of sustainable and non-sustainable modes, ii) identify factors affecting mode shift behavior of city residents between transit and other modes, and iii) investigate the impacts of for-hire-vehicles (FHVs) and bike sharing services on transit ridership. Discrete choice modeling approach was adopted to identify factors influencing sustainable and non-sustainable mode choice. NYC residents with positive attitudes toward sustainable modes were more likely to use sustainable modes. Sustainable modes usage decreased with personal vehicle ownership. People with a higher level of education showed lower usage of non-sustainable modes. Increasing ADA compatibility of sustainable travel modes and associated transportation infrastructure could increase sustainable mode use among people with a disability. Residents of four boroughs in NYC (i.e., Brooklyn, Queens, Bronx, and Staten Island) were found to use non-sustainable modes significantly higher compared to Manhattan residents. Borough-specific targeted initiatives could increase sustainable mode attractiveness in all NYC boroughs. Negative attitudes towards transit services were significant factors in mode shift. Improving transit service reliability, enhancing comfort and safety, and increasing accessibility could improve users’ attitudes toward transit services. Accessibility of personal vehicles increased the mode shift from transit use. People with higher education were less likely to shift from transit. In addition, emerging modes significantly influenced the mode shift from transit. Negative binomial (NB) models with the Bayesian estimation technique were developed to study emerging mobility services\u27 impacts on transit ridership. The number of FHV end trips within a subway station (quarter-mile distance) was found positively associated to higher transit ridership. FHV trips ending within subway station area act as first-mile connections and increased transit ridership. Marking designated areas for FHV trip pick-up and drop-off near all transit stations could improve the first and last-mile connection to transit and help increase the transit ridership. Citi Bike trips ending within a subway station service area did not significantly affect transit ridership. Bike sharing network should be well-connected to subway stations to encourage more people use the bike-sharing system to access the subway stations. By increasing the quantity of DOT bike racks near subway stations, NYC could develop a bike-supportive transportation system. This dissertation advanced the understanding of emerging travel behavior among residents in NYC and the impacts of emerging mobility services on transit ridership. Transportation agencies and policymakers can develop critical policies and investment decisions based on the identified significant factors to promote sustainable modes and reduce auto-dependency. Moreover, the research findings can be used to create a safe and sustainable mode-friendly environment and improve transit services that could increase positive attitudes/perceptions among city residents towards sustainable modes and increase transit ridership

Barcelona Virtual Mobility Lab: the multimodal transport simulation testbed for emerging mobility concepts evaluation

New sustainable mobility concepts and smart resilient ideas are arising every day. However, there is not an easy way to bring these ideas into reality, or to test how good they are as mobility solutions. Virtual Mobility Lab offers the opportunity to evaluate the impact of new mobility concepts before taking them to the real world. In this work, a multimodal macroscopic traffic simulation model of the Barcelona Metropolitan Area is developed, including both public and private transport network. This paper explains the remarkable features developed for this model, such as the network hierarchy and the multimodal public network interchangers, allowing demand to exchange between public transportation modes along their origin-destination paths.Peer ReviewedPostprint (author's final draft
