"If adjustments weren't made, the circuit would have been made more efficient a while ago."
In the heart of the city, the Westring is a bustling thoroughfare that sees heavy traffic throughout the year. However, during the holiday season, the situation takes a turn for the worse, with traffic backups of over 300 meters not uncommon.
One potential solution to this problem lies in the optimisation of traffic light timing at the Graefrather Straße intersection, where the Westring and Kaiserstraße meet. Unfortunately, this is an area where optimal timing is rarely seen, due to several common challenges.
Firstly, many intersections operate on fixed or pre-set timing plans, designed for average daily conditions. These plans may not accommodate the significantly increased holiday traffic volume effectively.
Secondly, without sensors or adaptive traffic control systems, the signals can't adjust to sudden or seasonal surges in vehicle numbers. This leads to inefficient green light allocation, causing longer queues especially during peak holiday periods.
Thirdly, the intersection of Graefrather Straße with Westring and Kaiserstraße involves multiple traffic flows with potentially competing priorities. Optimising signal timing in such a situation requires detailed analysis and regular adjustments based on up-to-date traffic data, which may not be performed frequently.
Fourthly, traffic management authorities might prioritise optimization efforts on intersections with historically heavier or more critical congestion, leaving others relatively static unless complaints or studies highlight a problem.
Lastly, holiday season traffic often includes more irregular flows—holiday shoppers, tourists, and event-related traffic—which differ from regular commuter patterns, making it harder to predict and optimise signal timing without adaptive systems.
In light of these challenges, it's clear that the root cause is often the use of static or insufficiently adaptive traffic signal timing schemes combined with seasonal traffic surges and possibly limited adjustments by traffic planners during the holiday period. Implementing adaptive signal control technology or reviewing the timing plans seasonally could help alleviate backups at this intersection.
It's worth noting that Norbert Bernhardt, a city official, is not mentioned as being directly related to the traffic issue or the car-free zone consideration regarding Kaiserstraße.

Adopting adaptive signal control technology at the Graefrather Straße intersection could potentially improve the efficiency of traffic flow, as current fixed timing plans may struggle to accommodate the increased vehicle numbers during the holiday season. Moreover, updating traffic signal timing plans seasonally would better address the irregular traffic flows characteristic of the holiday season, thus reducing traffic backups on the Westring.
