Department for Transport Modelling shows potential for driverless vehicles to cut delays
On major roads where traditional vehicles outnumbered automated vehicles benefits are relatively small, but increase as the percentage of driverless cars on the roads increases - when measuring peak traffic periods with a maximum of up to 100% of driverless vehicles we saw journey times reduced by more than 11% and delays cut by more than 40%

On urban roads benefits are seen in peak traffic periods even with low levels of automated vehicles on roads - benefits include a 12% improvement in delays and a 21% improvement in journey time reliability

How does heavy air pollution in Beijing form and where does it come from?

Normally, ground level pollution mixes with air higher in the sky.  Increased pollution leads to a lowering of the height of the mixing layer, concentrating the pollution.  High humidity and secondary chemical reactions in the air add to the levels of pollution.  Long distance pollution is mainly from coal burning in power stations, this is added to by local pollution from vehicles.   (NB if you read this article – “advection” means wind)

Living near major roads and the incidence of dementia, Parkinson's disease, and multiple sclerosis: a population-based cohort study The Lancet 
The adjusted hazard ratio (HR) of incident dementia was 1·07 for people living less than 50 metres from a major traffic road (95% CI 1·06–1·08), 1·04 (1·02–1·05) for 50–100 m, 1·02 (1·01–1·03) for 101–200 m, and 1·00 (0·99–1·01) for 201–300 m versus further than 300 m (p for trend=0·0349).   People who lived in a major city, within 50 metres of a major road and who did not move house for the duration of the study had the highest risk at 12%.  No association found with Parkinson’s disease or multiple sclerosis.   Air pollution should be factored into planning, and building design to reduce exposure.
