NordicWay 2 Swedish pilot : final report
Publication details: [Norden] : NordicWay, 2020Edition: Version 1.0Description: 168 sSubject(s): Online resources: Abstract: The Swedish pilots in NordicWay 2 were based around four service clusters: Emergency vehicles warning, Traffic signals, Access control and Road Work Warnings. For each of these clusters one or several services were developed, implemented, piloted and evaluated. The pilots took place in real traffic in the cities of Stockholm, Uppsala and Gothenburg. Vehicles for the pilots are provided by industry partners. A hybrid communication was used with cellular as the primary means of communication, supplemented by ITS-G5 for road works warnings with an Interchange node developed to support the transfer of messages across vehicles, OEMs, infrastructure and service providers. In Sweden, the quality-of-service (Technical) evaluation focused on latencies. For the various pilots, a couple of different setups were used for transmission of messages from one end to the other through the common interchange node. The latency measurements were done separately for different C-ITS services. As could be seen from the results in Sweden, variations in latency over time show how different factors and conditions in IT infrastructure can impact latency both short and long term. This highlights the need for designing solutions that are robust and scalable. It also shows the importance of constant monitoring of the KPIs of the complete system to make sure that data is usable for end-consumers. For the purpose of the pilots, the latencies did not hinder the piloted services.The Swedish pilots in NordicWay 2 were based around four service clusters: Emergency vehicles warning, Traffic signals, Access control and Road Work Warnings.
