In which we solve all traffic problems forever

In pure­ly coin­ci­den­tal tim­ing just before an elec­tion, the Nation­al Par­ty is hand­ing out new roads in an Oprah-like fash­ion. You get a road, and you get a road and YOU get a road. How we’re going to get a cou­ple of bil­lion dol­lars of new roads out of a bud­get full of holes for […]

Bypass surgery complete. Has the patient survived?

At last, the final stage of the bypass has been opened, and the decades-long dra­ma is draw­ing to an end. The Dom­Post reports…

At 6am yes­ter­day, south­bound traf­fic was direct­ed from The Ter­race Tun­nel onto a one-way Vivian St via a new off-ramp.

At the same time, Buller and Ghuznee streets revert­ed to two-way streets.

Tran­sit New Zealand project man­ag­er Jon­nette Adams said some motorists had teething prob­lems with the new lay­out, but were most­ly cour­te­ous to each oth­er. Some “tweak­ing” of inter­sec­tion lights helped alle­vi­ate con­ges­tion on oth­er routes link­ing with the bypass.

A team of engi­neers would be on hand today to make sure things ran smooth­ly, Ms Adams said.

Tran­sit opened the north­bound sec­tion of the bypass in Decem­ber.

Mean­while, frus­trat­ed Welling­to­ni­ans are turn­ing to the Web to vent their anger at delays caused by the region’s trans­port infra­struc­ture.

Aha! Haven’t they just.

So, how was it for you?

Crazy Intersections of our time: #31

the madnessThis week, the stretch of Ade­laide Road where it inter­sects with Brit­o­mart Street/Herald Street, and then, a lit­tle fur­ther up the road, with Lux­ford Street.

As you can see on our hasti­ly assem­bled lit­tle map on the right there, North-flow­ing traf­fic splits into two lanes once it gets past the Britomart/Herald inter­sec­tion, so right-turn­ing traf­fic gets its own turn­ing lane into Lux­ford.

Now, this would work fine if there weren’t a cou­ple of 5 minute park­ing spots (out­side a dairy) in the straight-ahead lane (pho­to 2). Cars parked in that 5 minute spot (indi­cat­ed by blue in the graph­ic) act as a road­block, so once the turn­ing lane hits a red light, traf­fic quick­ly backs up to the point where no-one can actu­al­ly get into the straight-ahead lane (pho­to 3).
