It has been reported that a pedestrian was hit by a bus at or near the war memorial junction in Chislehurst on the 8th April at 10.35 pm. This would appear to be an incident that will be classified as a “minor injury”. It has prompted renewed calls for a pedestrian phase at these lights which has been used as part of a political attack on the Bromley Council Conservative administration who recently rejected a petition on this subject.
It would be wrong to jump to conclusions over the cause of this incident until the full facts are known, but it’s worth pointing out that accidents late at night to pedestrians are often the results of alcohol consumption.
But let’s look at this issue rationally rather than emotionally.
Firstly is this location a particularly accident black spot? One can review that by looking at the Crashmap web site ( https://www.crashmap.co.uk/Search ) where you can easily see all the accidents in the area in the last few years. There are hundreds, and the nearby Chislehurst High Street is clearly an even worse problem area despite the fact that it has several pedestrian crossings which unfortunately many pedestrians ignore and choose to cross elsewhere. The same issue also arises at the War Memorial junction if you review details of the incidents at or nearby.
One of the key principles when deciding whether to spend money on road safety measures is to look at the cost/benefit ratio and where the most benefit can be obtained. There are limited funds available for road safety projects so the money needs to be spent where it can be most effectively deployed.
Looking at the past accident data is much better than relying on often ill-informed opinions on where the most danger lies. The number of minor accidents is a good pointer as large numbers indicate there is high risk of more serious injuries or fatalities (KSIs). KSIs have much higher values attached to them however you care to value them, but large numbers of minor accidents can point to where road safety budgets should be spent.
So people concerned with road safety should look at the statistical data on past accidents which they can easily do and you can obtain details of police reports on accidents (STATS19 reports) by using Freedom of Information Act requests. These provide a lot of information on the causes of accidents.
We don’t need to guess at the causes of accidents or where money should best be spent. You can estimate the benefit of introducing a pedestrian crossing for example, as against the cost; and compare it with the benefit of spending the money elsewhere. You can also calculate the possible disbenefit if traffic is delayed by a new crossing, or diverted onto minor roads.
That is what sensible councils like Bromley do. The unwise ones instead react to political clamour for simplistic solutions and as a result waste a lot of money on ineffectual solutions. You can see that in London boroughs such as Lewisham and Croydon where wide area 20 mph speed limits and speed humps everywhere have been installed at enormous cost and where the result has been a worse road safety improvement record than Bromley. Money has been wasted on ineffective solutions.
Bromley used to suffer from the busybody syndrome 20 years ago before I got involved in road safety issues. People who thought they knew best when they knew little about the science and failed to study the data.
We certainly do not want that scenario back again when money was wasted on effective schemes (such as the speed humps on Watts Lane/Manor Park Road).
Ignoring the advice of council officers is another failing of the busybodies. Good ones have both training and experience and should not be ignored unless there are very good reasons.
In summary, road safety decisions should not be made by amateurs, or uneducated grandstanding politicians, who have not looked at the statistical data or the causes of accidents and who are ignoring the wider implications of their decisions.
