Item Effects of toll road construction on local road projects in Indonesia(Journal of Transport and Land Use, 2019) Ayu Andani, I. G.; La Paix Puello, Lissy; Geurs, KarstThis study investigates the extent to which the construction of national toll roads in the Jakarta–Bandung region in Indonesia induces the development of local road projects nearby. In doing so, we disentangle the direct and indirect supply effects by considering the year of construction and urban development, respectively. We formulate four binary logit models to examine the direct and indirect relationships between toll road construction and local road projects. The dataset comprises 94 road projects planned or carried out between 2004 and 2016. We conduct interviews with local officials in the Jakarta–Bandung area to obtain data on the projects’ decision-making processes. Our modelling results show that existing and planned toll roads induce the development of local road projects both directly and indirectly. Local road projects tend to be developed in anticipation of the opening of a toll road. The changes in residential area and population around the toll roads also induce local road construction.Item Information, communication, travel behavior and accessibility(Journal of Transport and Land Use, 2013) Van Wee, Bert; Geurs, Karst; Chorus, CasperOver the past two decades many papers have been published on the impact of Information and Communication Technologies (ICT) on travel behavior, but the literature focusing on the impact of ICT on accessibility is relatively scarce. In this paper we give an overview of the impact of ICT on four components of accessibility as distinguished by Geurs and van Wee (2004): (1) the land-use component, (2) the transportation component, (3) the temporal component, and (4) the individual component. Conclusions are that first much more literature exists on the potential impacts of ICT on travel behavior than on its impact on accessibility. Second, we argue that ICT potentially has an impact on all four components of the concept of accessibility. Literature exists on the direct impacts but fails to incorporate impacts due to the interactions between the accessibility components. Third, there seems to be a major challenge in developing accessibility measures and indicators that include ICT, including those that measure the utility of accessibility. Fourth, in the area of ICT’s impact on travel behavior, many research gaps exist. Examples are the impact of ICT on overall activity and trip patterns, the impact of ICT on activities and trips at the household and social-network level, ICT as a means of avoiding congestion or mitigating its effects, and the role of the phenomenon of self-selection in the context of ICT use. Finally, a major challenge is to develop models for activities, including ICT-impacts, which combine high levels of behavioral realism with (econometric) tractability.Item Mobility and accessibility paradigms in Dutch policies: An empirical analysis(Journal of Transport and Land Use, 2021) Akse, Ruben; Thomas, Tom; Geurs, KarstTo promote sustainable urban development, transport policies need to change from a car-oriented mobility planning paradigm to an accessibility-based paradigm, integrating land-use and transport policies. This paper uses the concept of planning paradigms to describe the current status of municipal transport planning and problem framing. The dominant transport planning paradigm of 172 Dutch municipalities is determined, based on a conceptual framework with 24 mobility and accessibility planning criteria. Statistical analysis is then conducted to find linkages between the planning paradigm and transport, land-use, and institutional characteristics of the municipalities. We show that the mobility planning paradigm still dominates Dutch municipal transport planning, and the accessibility planning paradigm is mostly found in large cities and highly urban municipalities. However, we do find indications of slow change in the transport planning paradigms in Dutch municipalities, as older policy documents are more (car) mobility focused than newer policy documents. Further research is necessary to examine the evolution of the paradigm shift in municipal transport planning over time and what factors promote the realization of such a paradigm shift.Item Modelling route choice of Dutch cyclists using smartphone data(Journal of Transport and Land Use, 2018) Bernardi, Silvia; La Paix Puello, Lissy; Geurs, KarstThis paper analyzes the GPS traces recorded by cyclists in the framework of the Mobile Mobility Panel throughout the Netherlands. The objective of this paper is to analyze bicycle route choice via network attributes and trip length over a sequence of trips by approximately 280 bicycle users, who were asked to register their trips by means of a specific smartphone application. Approximately 3,500 bike trips were recorded throughout the Netherlands over a four-week period in 2014. The bike trips have been matched to a specific bicycle network built and updated by a Dutch cyclists’ union. Route choice models were estimated, using both the binomial logit model and the mixed multinomial logit model with Path-size logit model formulation. The chosen alternatives were part of the choice set for the mixed multinomial logit model. Also, the shortest route was generated for each origin-destination pair. The results show that trip lengths and trip distribution over time reveal a population sample much used to cycling, frequently and over long distances. Furthermore, when considering the composition of chosen routes in terms of link type, the usage of cycleway links is frequent. For repeated trips, the shortest route option tends to be chosen more; frequent cyclists, on systematic trips, tend to optimize their trip and prefer the shortest routes. This is even truer for males and for non-leisure trips. The estimated probabilities for both multinomial and binomial models show that the binomial model tends to overestimate the probabilities of choosing the shortest route. This result is stronger in non-leisure trips, where people tend to choose a more personalized route, instead of the shortest. This research contributes to the generation of a more efficient distribution of bicycle trips over the network. Future research can more specifically address the intrapersonal variation in route—destination choice given the availability of longitudinal data.Item Satisfaction with travel, ideal commuting, and accessibility to employment(Journal of Transport and Land Use, 2021) Pritchard, John P.; Geurs, Karst; Tomasiello, Diego B.; Slovic, Anne Dorothee; Nardocci, Adelaide; Kumar, Prashant; Giannotti, Mariana; Hagen-Zanker, AlexThis paper explores relationships between commuting times, job accessibility, and commuting satisfaction based on a large-scale survey applied in the Greater London Area (GLA), the municipality of São Paulo (MSP) and the Dutch Randstad (NLR). Potential accessibility to jobs is estimated under 3 different scenarios: reported actual commuting times (ACT), ideal commuting times (ICT), and maximum willingness to commute (MCT). In addition, binary logistic regression models, estimated using generalized linear modeling (GLM), are performed to assess the impact of these temporal preferences on the likelihood of being satisfied with commuting. As expected, ideal and maximum commuting preferences strongly impact the volume and spatial distribution of the measured accessibility to jobs. In the selected case studies, estimated ICT-based job accessibility significantly decreases total measured accessibility (60 to 100 percent), with those living in the lowest accessibility zones impacted most. Furthermore, although specific results varied between regions, the overall findings show an association between ACT and satisfaction. Likewise, commuting mode is found to be a strong predictor of travel satisfaction. Those actively traveling in all three metropolitan regions tend to be more satisfied with their commutes. Potential job accessibility is found to be only weakly associated with travel satisfaction.Item Stated choice model of transport modes including solar bike(Journal of Transport and Land Use, 2018) van den Berg, Pauline; Geurs, Karst; Vinken, Suzette; Arentze, TheoIn the Netherlands, e-bike ownership and use has rapidly increased over the last decade. A new type of e-bike, the solar bike, has recently been developed. The solar bike is an electric bike with solar panels in the front wheel that charges through sunlight. The aim of this study is to gain more insight in the factors affecting people’s choice between different transport modes, including car, public transport, regular bike, e-bike and solar bike. Based on a stated choice experiment among 308 respondents, a mixed logit error components model for transport mode choice was estimated. The results show that the solar bike is preferred for medium-length trips during daylight and in good weather. Land-use attributes such as good bike lanes, secured bike parking, congested roads and paid parking also have a positive effect on choosing a solar bike over a car. In addition, a latent class model was estimated to segment respondents according to their base preferences for transport modes. Three segments were identified: a segment with a preference for the solar bike, a segment of car lovers and a segment with a preference for public transport and a regular bike. Chi-square and ANOVA tests show that solar bike affinity is related to being female, older, Dutch, and having a positive attitude toward e-bike, solar bike, innovation and the environment.
