      <title>Carsharing in Switzerland: identifying new markets by predicting membership based on data on supply and demand</title>
      <link>https://trid.trb.org/View/1640760</link>
      <description><![CDATA[This study examines the relationship between the supply and demand variables that determine the probability of individuals joining a carsharing organization, using data from the Swiss National Travel Survey 2010 (demand) and the carsharing company Mobility (supply), located in Switzerland. Carsharing membership as reported in the Swiss National Travel Survey was used as the response variable for a discrete choice model (binominal logit), indicating that supply and demand variables are both significantly related to membership in carsharing organizations. By focusing on the relationships between the supply and demand factors, together with GIS mapping tools, potential markets for the expansion of carsharing in Swiss conurbations where demand is higher than expected based on the supply attributes (deviator groups) are identified. These markets are located in conurbations, are close to railways, support multi- and inter-modal life-styles and are suitable for the conventional round-trip model of carsharing. The results also suggest that individual preferences for transportation policies that aim at implementing mobility pricing for both public transport and car travel are positively related to carsharing membership. Therefore, we conclude that carsharing is not only an economic choice, but also a decision driven by a life-style involving sustainable mobility as a way of reducing infrastructure expansion.]]></description>

      <title>Route-recording on high resolution transportation network databases for National Transport Surveys: An option for valid and reliable distance measures?</title>
      <link>https://trid.trb.org/View/1305748</link>
      <description><![CDATA[The aim of this study is to investigate the results of route-recording within the Swiss National Travel Survey in the year 2010. The research questions include the following: (1) What level of accuracy and quality of georouting between addresses can be obtained within Computer Assisted Telephone Interview (CATI)-based national travel surveys? (2) What are the differences between estimated and routed distances for stages? (3) Is it worth it to switch from self-estimated distances to technological solutions in national travel surveys with a comparison between GPS and route-recording? It was found that within the method of route-recording, a high share of address-precise geocodes is a necessity for a successful routing fulfilled by the Swiss National Travel Survey 2010. Secondly, route-recording provides reliable and valid distance measures and is one way to overcome the difficulty in participants distance estimates. Thirdly, in its current form, it is not yet an alternative to GPS in national travel surveys, if one is interested in the actual routes travelled by survey participants. Especially there is development work necessary in the routing of non-motorised travel regarding both digital networks and the survey method. The paper concludes by drawing on the findings of this examination and formulating opportunities for improvement and enhancement.]]></description>

      <title>Route-Recording Technology for the Swiss Microcensus on Mobility and Transport 2010: An Innovative Alternative to Distance Estimations by Respondents</title>
      <link>https://trid.trb.org/View/1287342</link>
      <description><![CDATA[Route recording is a key new feature of the Swiss Microcensus on Mobility and Transport 2010 (MCMT 2010). Whereas in previous microcensuses information on distances was based on respondents’ estimates, the MCMT 2010 for the first time supplemented these estimates with effective distances determined by means of routing. Given the far greater accuracy of routed distance data compared with subjective estimates, the routed distances were applied for all motorized distance-related analyses. It was found that route recording provided reliable and valid distance measures and was one way to overcome the difficulty with participants’ distance estimates. But development work is needed on the routing of nonmotorized travel regarding both digital networks and the survey method. The paper concludes by drawing on the findings of this examination and formulating opportunities for improvement and enhancement.]]></description>

      <title>Precision of Geocoded Locations and Network Distance Estimates</title>
      <link>https://trid.trb.org/View/778847</link>
      <description><![CDATA[This paper addresses the accuracy of the geocoding of travel diaries, the relationships between different network-based distance estimates, and how exact estimates are when distances are self-reported. Three large-scale surveys in Norway and Switzerland demonstrate that very high precision is possible when survey protocol emphasizes the capture of addresses. The study uses the relevant and available databases and networks. Crow-fly, shortest distance path, shortest time path, and mean user equilibrium path distances are systematically related to each other, the pattern of their relationships is matched to theoretical expectations, and the impact of network resolution is reported. In the examples studied, medians of self-reported distances by distance band provide reasonable estimates of crow-fly and shortest distance path distances.]]></description>
