The impact of scheduling on service reliability: Trip-time determination and holding points in long-headway services

This paper presents research on optimizing service reliability of longheadway services in urban public transport. Setting the driving time, and thus the departure time at stops, is an important decision when optimizing reliability in urban public transport. The choice of the percentile out of historical data determines the probability of being late or early, while the scheduled departure time determines the arrival pattern for travelers. A hypothetical line and a case study are used to determine the optimal percentile value for long-headway services without and with holding points. If no holding points are applied, it is shown that the 35-percentile value minimizes the additional travel time to 25 % of the reference situation. In the case of holding, two holding points combined with a 30–60-percentile value yield the best performance: a further reduction of the additional travel time with 60 %.Transport en PlanningCivil Engineering and Geoscience

The middle classes and the remaking of the suburban family community: evidence from the Netherlands

This paper presents data on everyday life in three recently built Dutch suburban areas constructed under the Vinex national urban planning policy. Its focus is on family households and today’s division of work and care, social life and neighbourhood activism. The results show that suburbs are no longer breeding grounds for the traditional nuclear family. But, while the rate of working mothers is high, the limited use of professional child care still reflects the tradition that maintains that children are best cared for in the private domain. Having children is crucial for putting down roots and developing social networks. In contrast to the past, both working mothers and fathers are actively constructing family communities. The newly established family communities are firmly of the middle class and tend to exclude childless and lowerclass households. Neighbourhood activism involves both the reproduction of an unspoiled and orderly environment and the realisation of a suburban paradise for children. This paper further reveals differences in the suburban areas studied and discusses the false dichotomy between the urban and the suburban within the metropolitan area

What Makes a Good Cargo Bike Route? Perspectives from Users and Planners

Cargo bikes—bicycles made to carry both goods and people—are becoming increasingly common as an alternative to automobiles in urban areas. With a wider and heavier body, cargo bikes often face problems even in the presence of cycling infrastructure, thus limiting their possibilities of route choice. Infrastructure quality and the route choices of cyclists have been well studied, but often solely based on a quantitative approach, leading to tools such as BLOS (bicycle level of service). With various designs of cargo bikes being used for a wide range of purposes, the route choice of cargo bike users is difficult to generalize. This study combines quantitative and qualitative approaches in order to explore what is important for cargo bike users’ route choice, and how this knowledge can be effectively used for planning. Our results suggest that while some general preferences exist, route choice involves complex dynamics that cannot be fully explained by quantitative measures alone: in addition to understanding “what” is important for cargo bike users, we need to understand “why” it is important. Furthermore, route choice is also influenced by the city context, making a study tailored to the local context essential
