De­signer of traf­fic-strad­dling bus de­fends con­cept

China Daily (USA) - - CHINA - By CHI­NADAILY

Song Youzhou, de­signer of the tall, lane-strad­dling bus known as batie, which al­lows cars to pass be­neath, said the bus can run smoothly de­spite doubts peo­ple have raised, pa­per.cn re­ported on Mon­day.

The fea­si­bil­ity of the so-called Tran­sit El­e­vated Bus was ques­tioned af­ter a test run ear­lier this month in Qin­huang­dao, He­bei prov­ince.

The bus, 4.8 me­ters high, 7.8 me­ters wide and 22 me­ters long, is de­signed with a pas­sen­ger area, with a ca­pac­ity of 300, high above the road, ac­cord­ing to its maker, TEB Tech­nol­ogy Devel­op­ment Co.

The legs of the bus reach over lanes of or­di­nary traf­fic, cre­at­ing a sort of mov­ing tun­nel. Ve­hi­cles less than 2me­ters high can pass be­neath it.

The bus was de­signed to re­lieve traf­fic pres­sure on roads, the com­pany said.

But me­dia and ne­ti­zens ques­tioned whether the bus would re­ally work as ex­pected, be­cause some ve­hi­cles are taller than two me­ters and the huge ve­hi­cle could meet many chal­lenges on the road.

Ac­cord­ing to Song, more than 90 per­cent of the ve­hi­cles in cities are sedans and SUVs which are 1.6 m to 1.8 m in height.

“Most of them can run un­der the bus, thus help­ing im­prove the uti­liza­tion rate of roads,” Song said.

About how to cross ex­ist­ing bridges, Song said the TEB con­cept en­vi­sions vari­able de­signs for dif­fer­ent cities based on the width of roads and char­ac­ter­is­tics of bridges along its route.

“If the bridges are low, the top cover of the TEB will be made to be ad­justable up and down, al­low­ing it to pass,” Song said.

Some ne­ti­zens also ques­tioned whether the bus, large as it is, might weigh too much.

Song said a TEB carriage weighed about 36 met­ric tons at most, which in­cluded the weight of the carriage and 300 pas­sen­gers. That’s less than trucks car­ry­ing stone, which usu­ally weigh 90 tons, he said.

Yang Tao, chair­man of Nan­jing In­sti­tute of City and Trans­port Plan­ning Co, was quoted as say­ing that even though the gross weight might be OK, either stand­ing still or mov­ing slowly, “the spe­cial struc­ture might not be safe run­ning at more than 30 km per hour”.

Ac­cord­ing to Song, coun­tries in­clud­ing Brazil, Spain, Mex­ico and Ar­gentina had ex­pressed in­ter­est in the buses.

The com­pany also reached agree­ments with sev­eral do­mes­tic cities to in­vest.

Song said it was ex­pected that the world would need 500,000 TEBs in the fu­ture.

“At pre­sent, we are just do­ing ex­per­i­ments,” Song said, adding that the TEB could be run­ning on roads by the sec­ond half of 2017.
