This research study aims at providing new insights regarding attitudes among residents towards the introduction of Mobility-asa-Service (MaaS). We were especially interested in finding out how likely residents would be willing to use MaaS when introduced in their place of residence. The study involved a quantitative survey and focus group interviews with residents in the Paleiskwartier district, in the city of 's-Hertogenbosch, the Netherlands. Our results show that positive attitudes towards MaaS are the most important factors for the intention to use MaaS, whereas socio-economic characteristics seem not to play a role. Moreover, our results also indicate that most residents are more likely to not use MaaS in the long run, but a considerable amount of them would be interested in trying it out, at least. Equally important, the introduction of MaaS pilots may experience a greater receptivity among residents who do not see car ownership and usage as very important aspects, who regularly use public transport and who are mostly concerned with the environment and with a healthy commuting lifestyle. Conversely, people who use the car on a daily basis and regard car ownership as a very important aspect are far less receptive to MaaS pilots. Therefore, the sole idea of MaaS as an environmentally friendly alternative to make car ownership superfluous may potentially be inefficient against avid car users.

Abstract

Geographical addressing is a key communication paradigm in emerging Intelligent Transportation Systems (ITS). In this paper, we address the issue of how to direct messages to roadside units (RSUs) in order to have them forwarded by the RSUs to the on-board units (OBUs) of vehicles in a certain specified destination area. For that purpose, we have extended the Domain Name System (DNS) to support geographically scoped queries. A query with specified geographical coordinates will be resolved by the extended DNS system to the IPv6 addresses of those RSUs that cover the area described by the geographical coordinates. In this paper, we further extend the proposal by introducing delegation of geographical queries to DNS servers lower in the hierarchy. Furthermore, we demonstrate the feasibility of the proposal by implementing and experimenting with a prototype.

Network monitoring allows network managers to get a better insight in the network traffic transiting in a managed network. In order to make the tasks of a network manager easier IntroductionComputer networks are complex communication systems that enable intensive interactions among users and services. Such interactions result in network traffic that should be monitored to check the health of the underlying communication infrastructure. Network monitoring, in addition, provides essential data to other network management processes, such as network optimization, accounting, and security. As a result, network monitoring turns out to be a critical task in any serious network management solution.Network monitoring tools help network managers (or other end users) to handle network information. They usually provide some kind of user interface that presents network information. Nowadays, many network monitoring tools are made available, each one of them having a particular purpose and highlighting different aspects of network information. Some network monitoring tools focus on the inspection of packets, for example, whereas others focus rather on the monitoring of flows. Network managers often choose a particular network monitoring tool for a particular purpose. It is desired although that the chosen monitoring tool presents network information in a clear and easy way.However, many of the current network monitoring tools lack to provide network traffic information at a geographical dimension. For some network manager's tasks, (e.g., attack tracking and user statistics) this feature could be desirable. Moreover, if a network manager would like, for instance, to get an overview of the geographical locations of network traffic passing by his/her managed network, he/she could get a simple but complete overview when a map, containing the geographical locations, is displayed.In this paper, we propose a monitoring tool prototype that allows network managers to visualize network information through multiple levels of abstraction by using geographical capabilities provided by the Google Maps API [1]. The main contribution of this work is that it provides network traffic information in a geographical dimension.
