Traffic-calming measures

The ultimate CO2 guzzlers!

What is intended as a remedy often turns out to be a source of cumulative harm. Take, for example, traffic-calming measures, which are now found in a bewildering variety. All too often, they achieve exactly the opposite of what they are intended to do. A drive through France’s villages serves as a prime example. But Switzerland and other countries are not a bit better!
THE KEY POINTS IN BRIEF
• Traffic calming measures increase fuel consumption and thus CO2 emissions.
• Speed bumps, traffic lights and road narrowings significantly impair the flow of traffic.
• More stop-and-go traffic leads to additional noise, congestion and wasted time.

When­ev­er I’m out and about in my motorhome, I dis­able the motor­way option on the sat-nav. After all, I want to see and expe­ri­ence the coun­try­side. That’s how I’ve dis­cov­ered some of the most beau­ti­ful spots in the world. But there’s a mas­sive catch, as a recent trip to the south of France revealed. You can cer­tain­ly no longer speak of a free-flow­ing jour­ney: dri­ving through most vil­lages turns into a ‘four-hill ski jump­ing tour’, a game of ‘traf­fic light hop­ping’ and a ‘mil­lime­tre game’. Stops and slow-mov­ing traf­fic char­ac­terise the dri­ving expe­ri­ence!

In almost every backwater, there’s a bump after another

The first thing you notice are the stacked asphalt humps, which real­ly do give you the feel­ing of being on a Four Hills Tour­na­ment. The jour­ney isn’t made any faster, how­ev­er – quite the oppo­site. The whole point of this traf­fic-calm­ing mea­sure is to bring road traf­fic to a sud­den halt. Many of these humps are so high that you can only nego­ti­ate them with­out dam­age at 10, or at best 20 km/h. Any­one dri­ving a low­ered vehi­cle is like­ly to hear the scrap­ing of their front, side and rear spoil­ers every sin­gle time. A clipped exhaust is then prob­a­bly the ulti­mate audi­to­ry expe­ri­ence. Where­as these speed bumps were once only found at vil­lage entrances, they now accom­pa­ny you through the entire munic­i­pal area in many places – some­times at very short inter­vals and con­sis­tent­ly with­in 30 km/h zones.

Isolated traffic lights

In many vil­lages, one also comes across traf­fic lights that do not appear to be designed to allow either pedes­tri­ans or road users from side streets to access the main road. They seem to have been installed at ran­dom. Based on my obser­va­tions, their pri­ma­ry pur­pose is pre­sum­ably to bring vehi­cles that do not strict­ly adhere to the 30 km/h speed lim­it to a halt. In any case, they turn red for no appar­ent rea­son.

Artificial constrictions become a matter of millimetres

But that’s not all. As an added bonus, some extreme­ly inven­tive ‘trans­port experts’ are treat­ing the ‘homo mobilis’ to arti­fi­cial­ly cre­at­ed bot­tle­necks. Con­crete planters, with or with­out flow­ers, raised paving and wind­ing road mark­ings nar­row the car­riage­way in many places, forc­ing dri­vers to slow down and, when there is oncom­ing traf­fic, to come to a com­plete stand­still. ‘Traf­fic experts’, mind you, who are far less imag­i­na­tive when it comes to infra­struc­ture projects designed to improve traf­fic flow!

CO2, noise and traffic jams guaranteed

For years, I have made it a habit to keep an eye on the on-board com­put­er, which dis­plays both the cur­rent and aver­age fuel con­sump­tion. Whilst dri­ving through French vil­lages – and, of course, not just there – one quick­ly realis­es just how coun­ter­pro­duc­tive these traf­fic-restric­tion mea­sures are. When pulling away after one of the many enforced stops, fuel con­sump­tion shoots up to three to five times the fig­ure it was show­ing whilst dri­ving smooth­ly. As a result, the aver­age con­sump­tion negates all efforts to dri­ve eco­nom­i­cal­ly and eco­log­i­cal­ly. The read­ings prove unequiv­o­cal­ly that I dri­ve far more effi­cient­ly on the motor­way at a speed of 130 km/h.

Anoth­er aspect that has the oppo­site effect to what is intend­ed con­cerns traf­fic noise. When a vehi­cle pulls away, the engine nat­u­ral­ly revs up, thus caus­ing more noise than when it is purring along at a steady pace. The fact that slow­ing down road traf­fic ulti­mate­ly leads to a mas­sive increase in traf­fic jams is worth men­tion­ing here, if only in pass­ing. These con­stant, time-con­sum­ing and nerve-wrack­ing peri­ods of stand­still nat­u­ral­ly make your hair stand on end, and any­one who has to go through life bald will stand out due to a ‘full-head blush’. I wish to high­light yet anoth­er fac­tor con­tribut­ing to dam­age to health. Yet, bear­ing in mind all the traf­fic-calm­ing mea­sures and, more gen­er­al­ly, the atti­tude of cer­tain cir­cles towards mobil­i­ty, one must, for bet­ter or worse, speak of a sick soci­ety any­way.

Measures on an epidemic scale

Any­one who wants to take the easy way out and sim­ply point the fin­ger at France is bound to be dis­ap­point­ed. Although the Romans would prob­a­bly say, ‘Those Gauls are mad!’, these ten­den­cies to obstruct traf­fic can also be observed in Switzer­land, Ger­many, Aus­tria and many oth­er Euro­pean coun­tries. In Switzer­land, sim­ply because of the high pop­u­la­tion den­si­ty, there isn’t the same fre­quen­cy of speed bumps. Here, a mis­guid­ed pedes­tri­an reg­u­la­tion sys­tem, traf­fic lights, bus stops on the car­riage­way, con­crete blocks in the lane and a road infra­struc­ture that lags behind require­ments ensure that the speedome­ter nee­dle points to 0 km/h more often than one would like. And because the dis­tance from one town to the next is so short, this alone results in an almost epi­dem­ic fre­quen­cy.

The conclusion

So whilst the intro­duc­tion and increase of exist­ing trans­port charges are press­ing ahead at full speed, mobil­i­ty is being grad­u­al­ly cur­tailed. The con­se­quences of this are high­ly dam­ag­ing from an eco­nom­ic, envi­ron­men­tal and social per­spec­tive. Once again, I came to the real­i­sa­tion that ide­ol­o­gy and intel­li­gence can­cel each oth­er out!
