I artiklen viser vi således, at når forskningsområdet retter sig mod at analysere international arbejdsmobilitet i forhold til mobilitetsadfærd og betydningsmønstre, kan det dynamiske web-spørgeskema medvirke til at reducere kompleksiteten både i forhold til respondentens indtastninger, og de data forskeren efterfølgende skal behandlede. Samtidig vises det, at metoden har en række fordele, når det gælder om at kortlægge høj-mobile medarbejderes bevægelsesmønstre, da disse ofte er væk fra deres 'normale arbejdsplads' og vanskeligt lader sig indfange via et traditionelt postomdelt spørgeskema. Afslutningsvis diskuteres, hvordan anden generation af elektronisk baserede spørgeskemaer yderlig kan medvirke til at styrke dataindsamlingen, når det gælder om at kortlægge høj-mobile individers bevæge...

Frem til august 2019 har der været fokuseret på tidligere undersøgelser, udviklingen i transportmønstrene på tværs af Øresund, og forskelle og ligheder i modelgrundlag og metoder mellem Danmark og Sverige. Den samlede analyse forventes færdig inden udgangen af 2020.

Dynamics in Logistics, 2018

However, how to use this valuable source, still is not unveiled for various domains, such as also for the transportation sector. Accordingly, this research aims at examining the potential of textual data in transportation. For this purpose, a case study was designed on public opinion towards the adoption of driverless cars. This case study was framed together with the Danish road directorate, which is, in this case, the problem owner. Traditionally, public opinion is often captured by means of surveys. However, this paper provides demonstrations in which public opinion towards the adoption of driverless cars is examined through the exploitation of newspaper articles and tweets using topic modelling, document classification and sentiment analysis. These analyses have for instance shown that Text Analytics may be a supplementary tool to surveys, since they may extract additional knowledge which may not be captured through the application of surveys. In this case, the Danish Road Directorate can use these result to supplement their strategies and expectations towards the adoption of driverless cars by incorporating the public's opinion more carefully.

The paper uses survey data (N ¼ 1427) collected in eight Beijing neighborhoods. The analysis is carried out by means of principal component analysis and multinomial logistic regression analysis. The respondents were generally more positive towards continuing cycling or cycling more in the future than towards car purchasing. The perceived cycling environment was found to be associated with respondents' attitude towards future cycling and car purchasing. The higher the level of satisfaction with the clarity of cycling space allocation and the higher the agreement with pro-cycling policies, the higher the probability that the respondents will cycle in the future and the lower probability that they will buy a car. Associations with current travel behavior indicate that long everyday travel distances (e.g. 10 km to work or longer) negatively affects the respondents attitude towards their future cycling, whereas short everyday travel distances up to 2 km are positively linked to future cycling prospects. Non-car owners' attitude to future car ownership is strongly linked to socio-demographic status-low education and low income level groups seems to be most unlikely to take up driving in the future. To encourage people to cycle more and drive less, policy should direct efforts to promoting the clarity of cycling space on the street and strengthen pro-cycling policies. Attention should also be given to stabilizing the current travel modes of non-car users, including promoting the image of cycling, improving the service of walking, cycling, public transport and generally by introducing attractive alternatives to private car ownership.

Based on a survey including inhabitants of Copenhagen (n = 1110) and Stockholm (n = 1191), this study investigated whether cyclists in Copenhagen and Stockholm experience the transport systems in the two cities differently, and to what extent cycling perceptions can explain differences in cycling level (minutes of cycling) among cyclists. Cycling levels are much higher in Copenhagen than Stockholm, and cyclists in Copenhagen perceive a higher prioritisation in traffic, feel safer, and perceive a higher ability to reach their destinations by bike. Using ordered logit models, we examined the effect of different factors on cycling level among cyclists in both cities. Those who live in Copenhagen have higher levels of cycling even when other independent variables are included in our model. Other significant factors were employment, which increased cycling, and car access, which decreased cycling. Being female was related to higher cycling levels in Copenhagen, but not in Stockholm. The only significant cycling perception was the perceived ease and feasibility of getting to important destinations by bicycle (cycling autonomy). Results of a similar analysis including non-cyclists led to comparable results. The results suggest that differences in cycling levels between the two cities are related to the overall mobility culture of the two cities (in particular different policies, norms and infrastructure), while individual/micro-level factors, appear rather inadequate for understanding urban differences. Highlights • Cycling behaviours and perceptions were surveyed in Copenhagen and Stockholm. • Cycling level (minutes of cycling) was much higher and cycling was perceived more positively in Copenhagen compared to Stockholm. • Living in Copenhagen increased cycling when other relevant factors were controlled for. • Other significant factors included being employed and not having access to a car. • A significant interaction was found between gender and city of residence.

Grundlaget for beslutningerne der skal tages i forbindelse med samarbejdet, er til dels bygget op over 3 delanalyser over byudviklingen i Østjylland. Én af delanalyserne omhandler interaktion, hvor trafikken mellem de østjyske sogne bl.a. skal modelleres, dette paper omhandler opbygningen af denne model og til dels outputtet. Modellen udregner bil og togtrafikken mellem sognene i Østjylland, som antal ture pr. døgn. Grundlaget for beregningerne er befolkningstal og antal arbejdspladser

A national cycling index, a bike-traffic-index, was established in 1985, based on bike-flows continuously counted in locations all over the country. The number of counting stations included in the index has been increased over time to improve reliability and allow support for the development and assessment of policies aiming to maintain and further increase cycling. The index is partly fed by the Road Directorate and partly by the municipalities. With its current 61 counting stations in operation, the bike- traffic-index is still 'thin' compared to the equivalent car-traffic index, but it does provide consistent evidence on changes in cycling on Danish roads. The paper compares the bike-traffic-index with travel- survey data as indicators of changes in cycling, it presents the methodology and accuracy of the bike-traffic- index, and finally, it discusses its desir...

I overensstemmelse med andre undersøgelser forventer danskerne at køre mere i bil i en situation med helt selvkørende biler. Forventningen dækker både over øget kørsel hverdage og weekends/ferie, længere transportafstande, samt over at forskellige grupper der i dag enten ikke kan køre i bil, eller kan lide at køre bil, forventer at kunne køre mere. De fordele som befolkningen forventer at selvkørende biler giver er især øget sikkerhed, aflastningen fra køre-opgaver og muligheden for at slappe af undervejs. Bekymringerne knytter sig til at miste færdigheder og tabe kontrol, samt spørgsmål om ansvar og muligheder for misbrug/hacking. I forhold til accept og hvem der forventninger at bruge selvkørende biler når det bliver muligt, afspejler undersøgelsens resultater både en sammenhæng med behovet for biltransport, oplevelsen af træ...
