Traffic flow on A4 Leiden improved by driving advice

Faculty of Civil Engineering and Geosciences Building 23 Stevinweg 1 2628 CN Delft Room: 4. Will traffic flow improve when motorists are assisted in their choice of main or parallel lanes? The answer is yes. Rijkswaterstaat, TU Delft and Zuid-Holland Bereikbaar conducted a pilot project in collaboration with Flitsmeister in the past months. During the morning rush hour, some of the Flitsmeister users driving towards Amsterdam were advised to take the parallel lane. This resulted in a better distribution of traffic between the main and parallel lanes. Despite the increasing traffic, traffic flow on this section of the A4 remained the same, which is partially due to this pilot. in a survey after the trip, users of the app also indicated that the notification was perceived as positive.
