Swedish engineer Sebastian Hasselblom has developed a new type of roundabout. Its design is to reduce the risk of collision compared to current multi -lane roundabouts.
The simulations have shown that the likelihood of bumps on new roundabouts drop by 72 percent, and the bandwidth increases by about 22 percent. They were called “Hasselcirkeln” (literally “near Hassel”) from the name of the engineer who developed them – Sebastian Hasselbloma.
Near Hassel. New type of roundabout
The first new type roundabout is to be built soon in the Swedish city of Uppsala. Two such intersections will be located in the north-eastern part of the city. The possibility of building new roundabouts from scratch in some places in the western part of the city is also being considered.
“The new project aims to reduce the number of collision points compared to current multi -lane roundabouts. In addition, the Hassel near Hassel aims to facilitate driving on roundabouts. On today's multi -lane roundabouts in some drivers 'unnecessarily' they give way regarding the new type of intersection.

“In the general approach, the roundabouts are safe types of intersections, mainly due to the fact that all vehicles are moving at relatively low speed. On the other hand, the occurrence of small accidents (incidents) is relatively frequent and, which is not less important, there are often” situations of close accidents “, in which the vehicle must, for example, brake strongly before another vehicle. For this reason, today's multi -lane roundabout can be in many cases. perceived as disordered and unclear for road users, “it was written.
“On roundabouts with double lanes, a driver in the inner lane is required to check if he is free in the outer lane when he intends to leave the roundabout. If at the same time the vehicle is located in the outer lane, a collision may occur. On roundabouts with double lanes, according to practice, use the inner lane, for example, when turning to the left. Driving all the time on the outer lane, which increases the risk of collision, “we read.
“In the case of Hassel roundabout, the lane is not allowed to change the lane between the inner and outer lane. The driver does not have to change the lane from the internal to external when leaving the roundabout. Instead, the driver can continue driving his lane from the traffic from entering to departure from the roundabout” – explained in the report.
