Rapid Change
 
Racetrack design is becoming an important part of modern Formula 1. Circuits such as the super-fast and super-smooth track at Magny-Cours in France and the famous street circuit at Monte Carlo in Monaco, have been modified to improve safety and overtaking as organisers upgrade facilities in a bid to keep their place in the F1 World Championship alongside more traditional venues. The British Grand Prix at Silverstone is a classic example. It is the same in the field of road construction, too, where the focus lies on making accident hotspots safer, or even avoiding them completely.

Each year Formula 1 returns to its roots on the Silverstone circuit in England, where races have been run since 1950. But can you imagine Formula 1 without Silverstone? In an effort to safeguard its future, the organisers have implemented a massive re-generation programme.

In total, more than 25 million euros have been invested – partly on improving the access roads and car parks. A great deal of care and sensitivity was needed for converting the track itself. At Stowe Corner for example, the run-off zone has been asphalted. When potential angles of impact are less than 30 degrees, the Federation Internationale d’Automobile (FIA) recommends a smooth, continuous track barrier, allowing the cars to slide along the crash barriers or walls more easily, and in so doing, reduce the impact energy considerably. Alternatively, there are now several new gravel traps at those corners with less dangerous angles of impact, plus modernised or extended crash barriers and fences – such as at Copse Corner at the end of the start/finish straight. This change has had a dramatic effect. “The race organisers have to keep up with the times,” said Gavin Fisher, chief designer at WilliamsF1. “Formula 1 needs tracks that fulfil the latest safety standards and at the same time satisfy the demands of the fans. Meanwhile, the drivers and teams also want an entertaining, challenging track.”

The organisers at Silverstone are not the only ones who have brought in the excavators to implement modernisation work. In an attempt to increase the number of overtaking possibilities, long corners are being converted into tight, wide hairpins, while at the same time safety is being improved with spacious run-off zones.

Monte Carlo: As a replacement for the crowded provisional pits at this famous circuit, permanent pit facilities with garages for all the teams will be built for the 2004 Monaco Grand Prix. Land will be reclaimed from the yacht marina to create the necessary space and an additional 5,000-seat grandstand will be erected.

Nürburgring: The ’Ring was converted for the 2002 season. As well as the start/finish straight, extra grandstands were added providing space for an additional 8,000-10,000 spectators. For 2003, the chicane before the final corner has also been modified. Two tighter corners and a short straight between them are designed to prevent short cuts over the kerbs, and at the same time to encourage overtaking.

Magny-Cours: Two new, right-hand corners before the Chateau-d’Eau hairpin provide new overtaking opportunities. Just before the start/finish straight, the widened track leads into the new Complexe du Lycee, which has to be taken at just 80 km/h. The new exit from the pit lane has been made safer because the cars can now return to the track at racing speed.

Budapest: The start/finish straight has been extended by 250 metres and now ends with a tight bend to the right. The corner has also been widened to make overtaking possible. At the same time, the run-off zones and the retaining fences have been enlarged. A tight right-hand corner has also been added just before the finishing straight.

Suzuka: This track has numerous corners and much larger run-off zones have been added. The organisers have also extended the safety zones in the Degner Curve and 130R corner. All the emergency routes around the track have also been renovated.

The benchmark for track safety is undoubtedly the brand new high-tech Circuit Paul Ricard near Le Castellet, France. F1 supremo, Bernie Ecclestone, owns this famous facility, and it’s now one of the most technologically advanced test circuits in the world. The run-off zones have been constructed from special, super-sticky asphalt, which is designed to slow the cars down faster, and cause less damage, than traditional gravel. In order to distinguish between the safety zones and the track itself, the run-off areas are painted with vivid red and blue stripes. Moreover, computer signalling systems have been installed which are designed to make the flag-waving marshals superfluous, plus the track features one of the most sophisticated irrigation systems ever to be installed on a race track, allowing teams to test with dry, intermediate and full wet tyres.

Many of these circuit based conversion measures are also boosting safety in modern road construction. If there is a high frequency of accidents, it is stipulated that the relevant accident hotspots must be made less dangerous. "Preventive measures should particularly be taken on country roads," says Dr. Christoph Lauterwasser, a safety expert at the Allianz Centre for Technology in Munich, “because that is where serious accidents often happen. Appropriate measures include safe overtaking zones, suitable speed limits and speed-monitoring devices, or protective devices such as barriers, for example, that can protect roads lined with trees.” As further possible points, Dr. Lauterwasser also suggested traffic-related light signals or flyovers at heavily frequented intersections.

Ideally, safety should be a focal point at the beginning of the draft phase of any new road improvement scheme. Most countries – and Great Britain is one – conduct road-safety tests, or safety audits, in parallel to the planning process. In Germany, for instance, after a pilot phase in the state of Brandenburg, safety audits have to be carried out for all renovations, extensions or new development work. They have the task of detecting safety flaws in the initial design, approving any traffic schemes and then recommending proposals to remedy any problems. In this way, testing by independent auditors guarantees additional safety aspects in the design.

While the conversion and safety measures in Formula 1 can be concentrated on 16 circuits, the road network in Germany alone covers a total area of over 230,000 kilometres – which makes the job for the road designers that much harder.
