Het delen van ongebruikte en/of onderbenutte middelen kan nieuwe verbeteringen opleveren in de logistieke waardeketen. In vijf sectoren van het stedelijk goederenvervoer, te weten stadslogistiek, bouwlogistiek, transport & warehousing (retaillogistiek), zorglogistiek en servicelogistiek, worden concepten voor het delen van diensten bestudeerd voor de hele stad Rotterdam. Op basis van onze belangrijkste case study-bevindingen kan worden vastgesteld dat er binnen de sectoren van het stedelijk goederenvervoer nogal wat verschillen bestaan
met betrekking tot de maturiteit van delen. In deze paper is per sector weergegeven wat de volgende implementatie stappen zijn.@en

Many studies about conducting activities while traveling start from the hypothesis that conducting onboard activities reduces the value of time (VoT). However, surprisingly limited empirical evidence is provided for this hypothesis. The few studies that aim at providing this evidence face methodological problems in the sense that effects attributed to conducting onboard activities are confounded with differences between groups. This paper further develops and applies a solution for this problem proposed by Wardman and Lyons (2016). In essence, this method includes constructing a within-person choice experiment, which involves that the same respondents make choices in a context that enables conducting activities, as well as in a context that does not enable conducting activities. This method is applied in a study that collected data from 820 train travelers in the Netherlands. The results show that as expected, the VoT in the activity context is significantly lower than the VoT in the non-activity context, which thus supports the hypothesis. Reduction in VoT due to conducting onboard activities is around 30% for commuters, while leisure travelers who prefer to read lose almost half their VoT value. In addition, this paper discusses how the estimated VoT reduction values can be interpreted as the Value of Activity (VoA), which can be used for appraising investments aimed at reducing the disutility of travel other than by means of reducing travel time, such as improving Internet connections.

Container port competitiveness is generally conceptualized as being driven by straightforward criteria, such as port costs, handling efficiency, hinterland connectivity, and the quality of infrastructure and services. Synchromodal freight transport service is an emerging and developing concept of freight transport operations, as shippers and carriers consider hinterland, short-sea, and deep-sea connectivity as major port choice criteria to run these port operations smoothly. Although scientists claim that synchromodality is a promising concept with a lot of potential advantages synchromodal transport is currently implemented at limited scale. In this study a survey is carried out among 30 different small/medium enterprises (SMEs) in the field of port logistics to identify the success/fail factors of using synchromodal transport in practice. Companies are classified as experienced or inexperienced users of synchromodal transport. The experienced users have a stronger attention to the operational factors of synchromodal transport. Their experiences with flexibility, availability of infrastructure, damage-control and specific data sharing seems to be determining factors in their usage of synchromodal transport. The non-experienced companies are hindered by ignorance of synchromodality and focus on issues such as lack of knowledge, how to start knowledge, lack of transparency and complexity of synchromodal transport. Our findings suggest that to increase the share of synchromodal transport it is necessary that companies and policy makers who want to encourage the use of synchromodal transport should make different action plans considering the level of experience of the enterprises.@en

Although many papers about conducting onboard activities start from the assumption that these reduce the value of time (VoT), surprisingly limited empirical evidence is provided for this assumption. This evidence is hard to find in regular cross sectional research due to a self-selection problem: Travelers that are time pressured are more likely to work on board, which may reduce their VoT, but their VoT may remain relatively high. As a solution for this problem, Wardman and Lyons (2016) propose to compare the VoT estimated from choices made by the same persons observed under two different conditions: travelers can conduct their favorite activity or they cannot. The difference between both VoT estimates can be regarded as the value of activities (VoA). Our paper is the first to apply this approach. The results provide evidence that conducting onboard activities indeed reduces the VoT. Furthermore, the VoA has the expected positive value. The paper presents VoA values for three common in train activities separate for commuters and leisure travelers as well as the VoT in the activity and in the non-activity condition. Furthermore, VoA and VoT relations with socio-demographic and trip characteristics are explored. Finally, an endowment effect is discussed: VoA is found to be higher for travelers that first make choices in the activity condition compared to travelers who first make choices in the non-activity condition. Implications for policymakers, transport providers and scholars are discussed as well implications for the Automated Vehicle (AV) area, because just like trains, AV’s allow conducting onboard activities.@en
