Pedestrians signals

There is, however, one caveat in this apparent panacea roundabouts may compromise the safety of older - especially visually impaired - pedestrians. These road users have difficulties in judging gaps from approaching vehicles (Lobjois and Cavallo, 2007), and so for them pedestrian signals are probably preferable. In addition, where roundabouts are not common, older drivers may not know how to negotiate them, and they are also slow to adjust to novel system. Thus, the impact of roundabouts on older road users needs more investigation.

A pedestrian stepping from the kerb has no indication of safe crossing movement from the pedestrian signals, which could lead to them stepping into the path of moving traffic. 

Summary risk of overshoot accidents High speeds on the High Street northbound approach to the traffic signals could lead to drivers failing to stop at the stopline, particularly when the road is wet. This could lead to vehicle—vehicle or vehicle—pedestrian accidents. 

Traffic signal junctions are more prevalent in urban than in rural situations. Right turning accidents and accidents involving pedestrians are particular safety concerns.

More complex or unusual signalling arrangements resulted in increased pedestrian accidents - in particular where there was an all-red stage for vehicles but not a red/green man signal on every arm. 

TRL Report PPR035 Traffic signal controlled pedestrian crossings on... 

Overall, there was no clear evidence of a difference in pedestrian casualty risk at stand-alone crossings and signal-controlled junctions. 

The red signal to vehicle traffic during pedestrian crossing periods should remove the sense of harassment experienced by some pedestrians from impatient drivers during the pelican flashing... 

The wider use of pedestrian stages at signal-controlled junctions should increase pedestrian convenience and reduce pedestrian—vehicle conflicts. 

Acddents involving high or inappropriate speed have reduced by 65%. Accidents involving failing to stop at traffic signals have reduced by 30%. Single-vehicle non-pedestrian accidents have reduced by 30%. 

Elderly pedestrians being in a state of uncertainty at traffic signals may result in them following others, going elsewhere to cross and trying to anticipate a break in traffic independently of the appropriate phase to cross.

Road Safety Audit Teams are sometimes asked to audit a new typ>e of scheme, or a scheme with new design elements within it for example, introducing a diagonal pedestrian crossing at a set of traffic signals or using a new type of safety fence. 

The list in Table 10.2 reflects those items that are difficult to fix within the constraints of the scheme, for example continuity of cycle route, and the Road Safety Auditors perception that more traffic calming may be required. It also reflects those items that the client feels are not safety issues, for example the implementation of antiskid surfaces at an improved set of signals or pedestrian facility where there is no record of existing wet skid accidents.
