The Ashman Phenomenon refers to an observed driving pattern in roundabouts , where drivers are prone to slow down or stop at the point of entry instead of going at their intended pace.

The origins of the Ashman Phenomenon

The term"Ashman Phenomenon" was created by a British traffic engineer Mr. Howard Ashman, who first became aware of the phenomenon in the 1970s.

What is the reason why the Ashman Phenomenon Happen?

The reason for the Ashman Phenomenon is still unknown, but there are several theories suggesting that the behavior is due to drivers' misperception of their primary concern or responsibility to yield towards other drivers.

Effect of Ashman Phenomenon on the flow of traffic Flow

The Ashman Phenomenon can cause significant delays and disruptions for traffic, as well as increased fuel consumption and emissions caused by drivers slowing down or accelerating.

Countermeasures to Minimize Ashman Phenomenon

To minimize the Ashman Phenomenon, it is essential to inform drivers of the rules and expectations of roundabouts and create roundabouts that have uniform and clear indications and signs.

Conclusion

"The Ashman Phenomenon is an intriguing and complicated driving style that continues to be a challenge for traffic engineers and researchers. While the exact cause is still unknown but it is obvious the behavior has significant impact on traffic flow as well as the surrounding environment.
