Information - Traffic trial Äulestrasse Vaduz

As part of an operational and design concept, a mobility corridor was defined for Äulestrasse in Vaduz. The corridor should primarily serve the handling of traffic and allow other uses such as stay, commercial uses, etc.. In the course of the elaboration, several variants for the possible design were shown, in order to meet the diverse demands on the street space.
The best of the variants examined, "Two-way crossing", is now to be tested in a multi-phase traffic trial. In it, a mobility space with two lanes and a center multi-use lane is proposed between the Adlerkreisel and Lindenkreisel. The center divider serves as a crossing aid for pedestrian traffic and allows for turning movements. Elements in the center divider can be used to avoid through traffic in the longitudinal direction. 
The question of whether such innovative traffic solutions work despite the high volume of traffic is to be tested by means of a traffic trial in Äulestrasse. Possibly necessary flanking measures could be derived thereby. For the traffic trial, different test phases will be arranged. In addition to the existing situation (phase 0), two phases will be tested and the traffic effects will be determined. This is to simulate the design of "two-way crossing" as elaborated in the Äulestrasse Vaduz operating and design concept. The following test phases will be investigated as part of the traffic trial:

Phase 0:

Phase 0 replicates the existing Aeulestrasse, serves as a reference and comparison to the other test phases.

Phase 1:

In the first phase, the bus lane from the Linden traffic circle to the post office building will be waived. A multi-use lane with markings will be marked in this area as a trial arrangement. Furthermore, a multipurpose lane will be simulated between Postgass and Adlerkreisel. The traffic signals will not be operated. Pedestrians have the possibility to cross the roadway at the existing pedestrian crossings or via the multipurpose lane. To facilitate the crossing and to increase safety, selective obstacles and elements will be installed in the multi-purpose lane so that it is not passable by the motorised individual transport in all areas. Individual turning relations will not be possible in phase 1. The speed regime will continue to be 50 km/h.

Phase 2:

The second phase also eliminates the existing bus lane from the Linden traffic circle to the post office building. The multi-use lane will be simulated for approximately the entire section between the Linden-Circle and the Adler-Circle. The traffic signals and pedestrian crosswalks will be eliminated. The left turn from the main road and the left turn from the access roads will be made impossible by elements in the multipurpose lane. The speed regime is to remain 50 km/h.

During the traffic trials, public transport will serve the Post and Städtle stops as usual. The bicycle traffic is led together with the motorized individual traffic and the public traffic in the mixed traffic. The sidewalks on both sides of Äulestrasse will continue to be available for pedestrians.
The traffic detour will be made or marked by means of signalization boards as well as mobile barriers, traffic cones and temporary ground markings.
The tests take place in each case over the duration of approximately two weeks, whereby consideration was given to events in Vaduz. The first phase will start on 15.05.2023 and end on 27.05.2023. After the retrofit, the trial for Phase 2 will take place from 01.06.2023 to 15.06.2023. 
The road users will be informed in advance from April 21, 2023 about the first phase of the traffic trial by information boards in the Äulestrasse. In addition, as a notice to the population, the individual phases of the traffic trial will be published in the newspaper.
In the context of the test arrangement a monitoring is accomplished. Comprehensive surveys of traffic flow, traffic volume and speed will take place during the trial in order to be able to make statements about the changes. The results of the monitoring will be compared with the current traffic regime (phase 0 =zero measurement) and evaluated accordingly.
