New Forest pony time. The rest of the year, the lives of the ponies are relatively unhindered unless they need veterinary attention or additional feeding, when they are usually taken off the Forest. The open nature of the New Forest means that ponies are able to wander onto roads. The ponies actually have right of way over vehicles and many wear reflective collars in an effort to reduce traffic fatalities, but despite this, many ponies, along with commoners' cattle, pigs, and donkeys are killed or injured in road traffic accidents every year. Human interaction with ponies is also a problem; well meaning but
Road traffic safety from becoming fixed-object crashes. The US has developed a prototype automated roadway, to reduce driver fatigue and increase the carrying capacity of the roadway. Roadside units participating in future Wireless vehicle safety communications networks have been studied. Motorways are far more expensive and space-consumptive to build than ordinary roads, so are only used as principal arterial routes. In developed nations, motorways bear a significant portion of motorized travel; for example, the United Kingdom's 3533 km of motorways represented less than 1.5% of the United Kingdom's roadways in 2003, but carry 23% of road traffic. The proportion of traffic borne by
