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.

Using sugar to make the world a sweeter place

Besides it mainly being used for sugar production, sugarcane has emerged as an important alternative for providing clean renewable energy. Dr Deepack Santchurn, who works in the sugarcane breeding department of the Mauritius Sugar Industry Research Institute (MSIRI), believes if he could contribute towards a more environment-friendly and renewable energy through the use of sugarcane biomass, he would consider himself having made a great leap towards a better world. 

Sugarcane is mostly known and exploited for the sugar in its cane stem. According to Dr Santchurn it is not the only thing the crop does well. “Together with certain grasses, it is the finest living collector of sunlight energy and a producer of biomass in unit time. Sugarcane is now recognised worldwide as a potential renewable and environment-friendly bioenergy crop.” 

Significantly more bioenergy can be produced from sugarcane if the production system is not focused on the production and recovery of sucrose alone but on the maximum use to the total above-ground biomass. Diversification within the sugarcane industry is of paramount importance. 

He has been able to identify a few high biomass varieties that can be exploited industrially. One of the varieties is a commercial type with relatively high sugar and low fibre in the cane stem. Dr Santchurn explains: “Its sucrose content is about 0.5% less than the most cultivated commercial variety in Mauritius. Nevertheless, its sugar yield and above-ground biomass yield surpass those of the commercial varieties by more than 24%. The genetic gains compared to commercial varieties were around +50% for total biomass yield and +100% for fibre yield. Its cultivation is strictly related to bio-energy production and the extracted juice can be used as a feed-stock for ethanol and other high-value products.”

Dr Santchurn received his PhD at the UFS’s Department of Plant Sciences during the Winter Graduation Ceremonies in June this year. His study leader was Prof Maryke Labuschagne from the Department of Plant Sciences.
