Traffic Circle on the UFS Bloemfontein Campus
The Department of Protection Services shares how to #BSafe at traffic circles.

For the majority of drivers, one of the most confusing driving laws is the correct use of a traffic circle, especially in Bloemfontein with the large number of smaller traffic circles constructed over the past few years; also across the University of the Free State (UFS) Bloemfontein Campus.

“In fact, many motorists do not know that there is a difference between a larger traffic circle and a mini traffic circle, other than their size. Can you really be frustrated if someone cuts you off at a traffic circle if you don't know the rules? Arrive Alive has shed some light on the issue,” said Cobus van Jaarsveld, Assistant Director: Threat Detection, Investigations and Liaison in the UFS Department of Protection Services.

What is the difference between the two circles?

A traffic circle is classified as large when it has a minimum diameter of about 16 metres and a 1,5 to 2 metre flattened kerb, which allows heavy vehicles to drive onto a small section of the circle. A mini traffic circle is normally not more than seven to ten metres in diameter and the entire circle is mountable for heavy vehicles.

Are there different rules for each?

Yes – the rule of thumb is that mini traffic circles, which are usually found in residential areas, have the same rules as a four-way stop – first come first served. For larger traffic circles, which are usually found at busy crossings to assist with the traffic flow, you must give way to the right.

Rules to remember at a large traffic circle

As you arrive at a large traffic circle, traffic coming from your right has right of way, regardless of how many cars there are. Wait until there is a gap in the traffic and then ease slowly into the circle. Watch out for other traffic in the circle and be aware that they may not be using their indicators.

Use your indicators

Signal when you are going to turn – switch your indicator on immediately after passing the exit prior to the one you intend taking. If you are taking the first exit, i.e. you're turning left, then flick on your left indicator and keep in the outside/left-hand lane. Keeping in the outside/left-hand lane also works well if you're continuing straight ahead, as your exit is very close. After you've passed the left-turn exit and yours is next, signal left and you're free. If you're turning right or performing a U-turn, keep in the inside/right-hand lane. Only signal left and change into the left-hand lane once you've passed the other exits and only yours is ahead.

Rules to remember at a mini traffic circle

The first vehicle to cross the line has the right of way, so it really works on the same principle as a four-way stop or yield sign. Proceed in a clockwise direction around the circle, without driving on it.

Tiny microbes may solve large problems of water contamination, says Prof Esta van Heerden

Small solutions for big problems

According to Prof Esta van Heerden, professor in the Department of Microbial, Biochemical and Food Biotechnology at the University of the Free State (UFS), this might hold some truth in current terms of water treatment strategies for waste and industrial effluents.

“There is little doubt in popular literature that eminent water crises are looming, not only with respect to the supply, but quality and effectiveness of various treatment options as well. The UFS’s Department of Microbial, Biochemical and Food Biotechnology is partnering with the Technology Innovation Agency to evaluate water treatment technologies that are applied worldwide and to extend these new or adapted options to innovative and interested clients in South Africa,” says Prof Van Heerden.

“The research focuses on using extreme microbes to tackle big contaminations and the results are amazing,” says Prof Van Heerden.

These microbes are fast becoming the stars on sites and developing these exciting systems allows for greener treatment options. It is fascinating that they can deal with metals, including chromium and uranium, cyanide, petroleum and diesel.

Of utmost importance is the development of a treatment for acid mine drainage.

“Interests have been overwhelming and thus far partners have allowed pilot scale development on their sites with very promising results. These initiatives are driven by responsible partners who strive to be innovative and develop sustainable technologies for good quality water that can be released in the environment,” Prof Van Heerden says.

The research group has set up a pipeline to serve the water communities’ needs. It provides an accessible toolkit for water analysis. A tailor-made treatment option is also developed and showcased in the laboratories. It has the added benefit that Geosyntec Consultants, USA, will ensure faster roll-out by sharing their vast experience on any related aspects.
