The  results had  shown  that this tr af fi c m anagem ent tool i s of i nt  er est  but di d not real ly  all ow sol vi ng the pr obl  em of chr  oni c congest ion obser ved i n the Mor ges East  j uncti on  zone. T hi s second phase of the PAPABI L ES pr  oj ect  proposes t  o evaluate and to compare t wo types of  r  esponse to thi s pr obl em . T he fir st consist s in  pr   olonging the acceler at ion lane of the Mor ges E ast   juncti on up to the Ecublens inter change, thus al  lowi  ng  the traff i c to fl ow out on 3 lanes bet ween these t  wo  points. T he second, typical appli cati  on of t he IT  S  field, i s the i mpl antati on of a r am p met er i ng  on  the Morges-east j uncti on ramp T hese eval uat ions  were  carr ied out by usi ng the  microscopi c sim ul at or  AI  MSUN, a t ool devel - oped at the Pol yt echni c Uni  versi  ty of Cat al unya, i n  S pai n. T he result s show  that  the const r ucti on of a thir d  lane between the Mor  ges  East junct ion and the E cubl ens i nt erchange woul d  al  low decr easi ng tr avel  ti mes on the studi ed secti  on  of al most 27 % and thi s in the case of ver y hi gh tr  aff  ic fl ows. This  incr ease of the net work perf or m  ance  is the r esul t of the addit i on of two posi ti ve  im  pacts  generated by the presence of the thir d lane,  the  suppr ession of the bot tl eneck at the exit of the  Morges   East juncti on and the incr ease in fl ui di t y  and aver  age speed. T he result s also show that ramp  meter ing does  not all ow  avoi ding the presence of  congesti on at the  Mor ges East juncti on. Never theless,  i t m akes  possibl  e the decrease of the pr opagat i on  upstr eam of the j  unct i on and especiall y t he durati  on in ti  me. Ram p  met er ing also makes possibl e to  reduce in a si  gnif i  cant way the del ays generated by  the presence of an acci  dent located downstr eam of the   junction. This decr ease  is part icularl y im - por tant  for medium demand f lows  (whi ch do not involve   congestion due to a lack of  capacity at t he Mor ges East  j uncti on) where reducti ons  of 40 % wer  e recor ded. T  hi s st udy made it possi ble  to concr etely eval uat e   the improvem ents that can be  achieved by t wo sol uti ons  of com pl et ely dif f er ent  charact eri  st i cs concer  ni ng i mpor tance, cost and  impl icat ion. It also all  owed com pari ng two types of  str ategi es  answer i ng a  pr oblem of capacit y lack: t  he i ncr ease of t he suppl  y or a bet ter dem and m   anagem ent.
