TRAFFIC jams in Portsmouth are getting worse, according to a recent survey.
The TomTom Traffic Index 2015 showed Portsmouth to be one of 14 of the UK’s 17 biggest cities where congestion had increased since 2013.
Average journeys in the city took 24 per cent longer than in free-flowing traffic, with evening rush-hour journeys taking as much as 45 per cent longer. Overall, average journeys in all the cities in 2014 took 29 per cent longer – compared with a figure of 27 per cent longer in 2013.
Across the UK, compared with figures in 2013, the survey found congestion in 2014 was worse in 14 of the UK’s 17 biggest cities, with Bristol the only destination where jams had eased slightly.
Figures for Sheffield and for Leeds/Bradford were about the same in 2014 as in 2013.
In addition to Portsmouth, congestion levels got worse over the past year in Southampton, London, Brighton and Hove, Nottingham, Leicester, Birmingham, Cardiff, Belfast, Edinburgh, Manchester, Liverpool, Newcastle and Glasgow.
Overall, average journeys in the cities in 2014 took 29% longer than they would in free-flowing traffic - compared with a figure of 27% longer in 2013.
The worst city for jams was Belfast, with average journeys taking 39% longer than in free-flowing traffic, with evening rush-hour journeys taking as much as 82% longer.
London was the next-worst city for hold-ups with average journeys taking 37% longer than in free-flowing traffic and 67% in the evening peak.
Other cities where drivers were particularly badly held up in the evening rush-hour were Manchester (with journeys taking 72% longer), Edinburgh (71% longer) and Brighton and Hove (59% longer).
TomTom said that in 2014 a typical UK city commuter with a 30-minute drive home spent an extra 66 hours stuck in traffic than they would have done on a free-flowing road.
Added to the 63 hours stuck in morning traffic, that amounted to 129 hours wasted in a year.
Worldwide, the worst city was Istanbul, with average journeys taking 58% longer than in free-flowing conditions, rising to as high as 109% in the evening peak.
Mexico City (55% longer on average) was the second-worst world city, followed by Rio de Janeiro (51%).
TomTom Traffic vice-president Ralf-Peter Schaefer said: ‘Road authorities and local governments can use traffic data to better manage traffic flow and businesses can plan smarter working hours, so their employees avoid travelling during the rush-hour.’
