Störningsfri stad - Visualized construction traffic planning for a city development without interference of construction traffic

According to Guerlain et al. (2019) the cost of materials represent 30-40% of the overall construction cost and in general the site receives 2-10 deliveries or 8-10 tons of material per day. During construction projects the demand of infrastructure capacity increase at the same time as the available capacity decrease. Construction transport in urban areas affect all types of stakeholders such as residents, freight transporters, municipal administrations, shop owners, businesses and tourists. They cause disturbances such as emissions, congestion, noise, prolonged travel-times, and increased risk of accidents. With the urbanization trend, the increase in number of construction transports and thereby disturbances will likely increase further (World Economic Forum, 2020). To decrease the disturbances caused by construction transports, we need to develop an overview of the total traffic situation during construction projects. The purpose of the project is to develop knowledge and competence that allow for the development of planning systems that can visualize the traffic impact of development and traffic plans during city planning. The goal is to decrease congestion, improve construction efficiency and make the city attractive during the construction time.

Involved parties are: RISE, VTI, Norrköping kommun, Swedish Traffic Administration, Linköping kommun, Uppsala kommun, City of Stockholm, Fastighets AB LE Lundbergs, Sankt Kors Fasigheter, Wiklunds Åkeri, Wellsec, Telenor, Byggföretagen, Logistikkluster Östergötland (Logistikia). Project leader is Linköping university, Department of Science and Technology.

The project has worked with three main issues:

1)      To develop a prototype for visualization of the traffic impact of construction traffic that can support collaborative planning between actors. The prototype is based on MatSim for traffic

simulation. Focus for the visualization part has been on understanding the needs of traffic and construction planners within local municipalities to support their work. This understanding has been gathered through workshops with Norrköping kommun, Linköping kommun, Uppsala kommun and City of Stockholm as well as Logistikia, Fastighets AB LE Lundbergs and Byggföretagen.

2)      To develop collaborative planning processes for construction projects and traffic planning. Focus here have been to understand how the prototype can be used in a process that help the implementation of construction logistics actions. The collaborative planning process has been identified with the help of applied research together with the municipality of Norrköping and the Swedish Traffic Administration, using project Ostlänken as use case.

3)      To identify possible data sources to support the understanding of construction transport patterns and the disturbances they cause. Sankt Kors Fasigheter, City of Stockholm (NDS), Wiklunds Åkeri, Wellsec, Uppsala kommun (BLC), and Telenor have supported the project with data or opportunities to test sensors for data gathering.

The project has rendered great interest and it is to present the final results during the autumn of 2021.
