Mini-roundabouts

Is a new mini-roundabout proposed at an existing crossroads junction safe ... [Pg.33]

More than 17 000 accidents occurred at roundabouts, including mini-roundabouts (9% of the total). [Pg.46]

Mini-roundabouts are often introduced at priority junctions as a traffic safety technique but have a poor record for fail-to-give-way accidents on former main road approaches. They have a poor accident record for two-wheeled vehicles. [Pg.49]

This document gives advice on the design of mini-roundabouts. [Pg.49]

A mini-roundabout with some entry deflection... [Pg.50]

For three-arm sites the mean accident rate for mini-roundabouts is similar to that of priority T-junctions and about 30% less than for signalled junctions. [Pg.50]

The accident severity at three-arm mini-roundabouts is lower than at three-arm signalled junctions and considerably lower than at 30 mph T-junctions. [Pg.50]

The average accident severity of accidents at mini-roundabouts is much lower than at priority junctions or at signalised junctions. [Pg.50]

Mini-roundabouts can generate accidents and should only be used where there have been more than four injury accidents in three years or as part of a traffic calming scheme. [Pg.51]

Four-arm mini-roundabouts have a worse accident record than three-arm minis. [Pg.51]

Over half of the accidents at mini-roundabouts involve failure to... [Pg.51]

On the A49 trunk road at Craven Arms, Shropshire, the measures implemented included gateways on each approach, speed cushions, mini-roundabouts, painted 30 mph roundels on patches of red surface, refuges and centre hatching on a red background through the village itself. [Pg.79]

The main road safety risks identified at the mini-roundabouts were ... [Pg.124]

Poor visibility to mini-roundabout signs (and to the belisha beacon and pedestrians)... [Pg.125]

Intelligent Speed Control 25 personal vehicles in Sweden were equipped with governors activated by beacons at city points-of-entry to limit inner city vehicle speeds to 50 km/h. The vast majority of participants preferred this adaptive speed control over other physical countermeasures such as speed humps, chicanes, or mini-roundabouts. 1 study (Almqvist, 1998),... [Pg.762]

The collision rate at all roundabouts (excluding mini-roundabouts) in London is... [Pg.53]

The DfT s annual Reported Road Casualties Great Britain does not report separately on mini-roundabouts. [Pg.55]

The collision rate at all mini-roundabouts in London is 0.28/year. [Pg.56]

This standard gives advice on the design of mini-roundabouts. There are sections on safety and road users specific requirements. The safety section quotes TRL report 281 referenced below. [Pg.56]
