CAN THE MULTIMODAL REAL-TIME INFORMATION SYSTEMS INDUCE A MORE SUSTAINABLE MOBILITY ?
No full textModern cities show an increasing interest in Advanced Traveller Information Systems (ATIS), with a growing attention to real time multimodal information. Through those systems, decision makers hope to achieve a shift from the car to alternative, environment-friendly modes of travel. Unfortunately, few comprehensive assessments have been undertaken in order to verify the actual contribution of ATIS to such modal shift. This paper aims at assessing the effects on travel behaviour of Optimod'Lyon, a multimodal real-time information navigator for smartphone, developed in Lyon in 2013 and launched in May 2015. To this end, a quali-quantitative approach was adopted, administering a questionnaire and organising focus groups before and after the test of the application. A stratified sample of 50 people living in the metropolitan area of Lyon was, likewise, involved. The Theory of Planned Behaviour was used as the theoretical framework for the questionnaire design, investigating attitudes, subjective norms and perceived behavioural control. To evaluate the behavioural change, data were analysed using parametric and non-parametric tests, factor analysis and binary logistic regression. Survey participants were initially interested on the Optimod'Lyon and showed a positive attitude towards its use. Prior to the test, they evaluated positively the travel planner , but this lessened over time and, after the test, the use of the different travel modes remained stable, showing a consistency on the most used mode, on behavioural patterns and attitudes, strongly related to habits and to the frequency of the past behaviour

The design of a Decision Support Tool for transport planning and management: the Torino Metropolitan Area case study
No full textThe challenges of the cities of tomorrow imply more and more an innovative approach in transport planning, based on the new technologies to collect and analyse the data needed to describe the mobility patterns. To this end, the big data are becoming the new paradigm for feeding the decision support systems and the use of business intelligent and dashboard are fundamental to properly visualise data. The paper aims at contributing to the design of the Decision Support Tool (DST) MOMA, for the benefit of decision makers, technicians working in the cities and the transport operators. MOMA is a multi-layer web viewer allowing to: a) give all the information of the multimodal transport network related to the Torino metropolitan area; b) calculate the Key Performance Indicators (KPIs) of mobility visualised through a dashboard; c) analyse the territorial information collected by all stakeholders, crossing them with mobility patterns. To this end a quali-quantitative approach was adopted, administering a questionnaire and organising 4 focus groups prior to the actual testing of the DST. It has involved a sample of 48 people (17 decision makers, 25 technicians and 6 transport operators) answering the questionnaire while a subsample of 31 respondents participated also to the focus groups. The survey was carried out to individuate the key features of MOMA (ex-ante survey) before its test in the Torino Metropolitan Area and, likewise, to gather data on: • the current access to the information of the different transport modes in the metropolitan area; • the current knowledge of planned and unplanned events influencing the mobility; • the current update and quality of mobility data; • the current data exchange with other bodies; • the main needs (data typology and data analysis) and what the users expect from the tool; • the attributes that the DST should have to support both the transport planning and management; • the use and calculation of the KPIs; • the users' willingness to pay (WTP) for the DST services. To study the collected data, a descriptive analysis of the questionnaires through the divergent stacked bar charts, consistency analysis (Cronbach alpha) and X2 test of Pearson were used as statistical approaches. The textual analysis was performed to go in depth in the focus groups content. The results showed a significant lack of data in the cities around Torino . Moreover, transport operators were not able to access to the information related to the transport services offered by the other companies with whom important synergies could be developed. Furthermore, the potential users of the DST have showed a broad diversity of requirements and hence, the dashboard should have different interfaces according to the user typology in addition to a public interface mainly devoted to the citizens. Finally, a set of KPIs has been selected to be included in the DST

Multimodal real time information systems: users' requirements and effects on travel behaviour
No full textModern cities show an increasing interest in Advanced Traveller Information Systems, with a growing attention to real time multimodal information. Through those systems, decision makers hope to achieve a shift from the car to alternative, environment-friendly modes of travel, thus enhancing the quality of the environment. Unfortunately, not many comprehensive assessments have been undertaken in order to verify the actual contribution of ATIS to such modal shift. The paper aims at supporting the design of the Multimodal Urban Navigator TueTO, according to the users' requirements (operational, ergonomics, performances). TueTO is a smartphone application providing the possibility to plan travels using real time information about all modes (car, public transport, bike, foot), including bike and car sharing and a car pooling module. A special attention is paid also to the potential of the application to spur the modal diversion through a real time and reliable information supporting the multimodality. To this end a quali-quantitative approach was adopted, administering a questionnaire and organising 24 focus groups prior to the actual testing of the application. It has involved a sample of 150 people living in the metropolitan area of Torino, stratified according to gender, age, presence of children in the household, plus origin and destination of their trips. The survey was carried out to individuate the key features of TUeTO (ex-ante survey) before its test in the Torino Metropolitan Area and, likewise, allowed gathering data on: • the main needs for passengers (all modes) and what they expect from the application; • the attributes that the tool and its services should have to induce passengers to address their behaviour towards more sustainable modes; • the reactions, the attitudes and users' responses to the new tool, thus providing crucial information for the design of the application; • passengers' willingness to pay (WTP) for such services. Hence time saving may be accrued thanks to the indications about the most efficient (travel time and cost) transport modes according to their specific travel constraints. The theory of planned behaviour was used as theoretical framework for the questionnaire design, investigating attitudes, subjective norms and perceived behavioural control. For the data analysis, descriptive analysis, parametric and non-parametric tests, factor analysis and binary logistic regression were used as statistical approaches to study the collected data and evaluate the effectiveness of the application in terms of behavioural change. Before the test, participants declared an interest on TueTO and a positive attitude towards its use. The results show that people expect easiness of use and high reliability besides information about travel time and cost and its environmental impact. Then, additional information not directly related to transportation is also requested: weather, ticketing functionality, POIs, etc. Participants suggested the possibility to select the modes according to their preferences and habits as well as to change the look of the app, colours, themes, etc. A vocal assistant was also requested. The interaction with social media seems important to the users who asked for the possibility of sharing information
The shape of D-glucosamine
No full textThe bioactive amino monosaccharideD-glucosamine has been generated in the gas phasevialaserablation ofD-glucosamine hydrochloride. Three cyclica-4C1pyranose forms have been identified usingFourier transform microwave techniques. Stereoelectronic hyperconjugative forces – essentially linkedwith the anomeric orgaucheeffect – and cooperative OH O, OH N and NH O chains, extendedalong the entire molecule, are found to be the main factors driving the conformational behavior. Theorientation of the NH2group within each conformer has been determined by the values of the nuclearquadrupole coupling constants. The results have been compared with those recently obtained for thearchetypicalD-glucose.Fil: Peña, Isabel. Universidad de Valladolid; EspañaFil: Kolesnikova, Lucie.
