Instal\u00adla\u00adti\u00adon of Roadsi\u00adde Units<\/h3>\n

In the TEMPUS test field, around 65 traf\u00adfic lights are equip\u00adped with roadsi\u00adde units (RSUs) that enable com\u00admu\u00adni\u00adca\u00adti\u00adon bet\u00adween infra\u00adstruc\u00adtu\u00adre and vehic\u00adles. A roadsi\u00adde unit acts eit\u00adher only as a trans\u00admit\u00adter or as a trans\u00admit\u00adter and recei\u00adver at the same time and can be used in dif\u00adfe\u00adrent ways depen\u00adding on the use case.<\/p>\n

Ope\u00adra\u00adting only as a trans\u00admit\u00adter, a RSU sends infor\u00adma\u00adti\u00adon about the cur\u00adrent signal sta\u00adte of a traf\u00adfic light (SPaT) and road topo\u00adlo\u00adgy of the respec\u00adti\u00adve inter\u00adsec\u00adtion (MAP). This infor\u00adma\u00adti\u00adon sup\u00adports auto\u00adma\u00adted vehic\u00adles in safe\u00adly crossing an intersection.<\/p>\n

As a trans\u00admit\u00adter and recei\u00adver at the same time, a RSU with return chan\u00adnel can addi\u00adtio\u00adnal\u00adly recei\u00adve data from vehic\u00adles and for\u00adward it to the traf\u00adfic signal sys\u00adtem for pro\u00adces\u00adsing. This func\u00adtion\u00ada\u00adli\u00adty is nee\u00added, for exam\u00adp\u00adle, to acce\u00adle\u00adra\u00adte public trans\u00adport buses or to prio\u00adri\u00adti\u00adze emer\u00adgen\u00adcy vehic\u00adles. Due to the RSU with feed\u00adback chan\u00adnel the vehic\u00adles can regis\u00adter at the traf\u00adfic signal sys\u00adtem and influence the swit\u00adching pha\u00adses, i.e. request green phases.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

Trans\u00admis\u00adsi\u00adon Tech\u00adno\u00adlo\u00adgies (ITSG5 and CV2X)<\/h3>\n

WLAN and cellular-based near-field com\u00admu\u00adni\u00adca\u00adti\u00adon tech\u00adno\u00adlo\u00adgies are being tes\u00adted which allows a gre\u00adat fle\u00adxi\u00adbi\u00adli\u00adty and varie\u00adty in appli\u00adca\u00adti\u00adon testing.<\/p>\n

Auto\u00adma\u00adted vehic\u00adles need safety-critical infor\u00adma\u00adti\u00adon within a frac\u00adtion of a second, espe\u00adci\u00adal\u00adly at inter\u00adsec\u00adtions, to be able to react appro\u00adpria\u00adte\u00adly. Curr\u00adent\u00adly, only near-field com\u00admu\u00adni\u00adca\u00adti\u00adon via ITSG5 (WLAN-based) and CV2X (cellular-based) gua\u00adran\u00adtees suf\u00adfi\u00adci\u00adent\u00adly short laten\u00adci\u00ades. In prin\u00adci\u00adple, both tech\u00adno\u00adlo\u00adgies offer the same ran\u00adge of func\u00adtions and dif\u00adfer only in the trans\u00admis\u00adsi\u00adon tech\u00adno\u00adlo\u00adgy used. Due to the lack of stan\u00addar\u00addiza\u00adti\u00adon, it is not yet pos\u00adsi\u00adble to pre\u00addict which tech\u00adno\u00adlo\u00adgy will pre\u00advail in Euro\u00adpe in the future. Non-time-critical appli\u00adca\u00adti\u00adons, such as public trans\u00adport acce\u00adle\u00adra\u00adti\u00adon, can also be hand\u00adled via the clas\u00adsic 5G mobi\u00adle net\u00adwork in the future.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

Data Trans\u00admit\u00adted to the Vehic\u00adles (SPaT\/MAP)<\/h3>\n

Via roadsi\u00adde units, infor\u00adma\u00adti\u00adon on road topo\u00adlo\u00adgy (MAP) and on the cur\u00adrent pha\u00adse of the traf\u00adfic signal sys\u00adtem (SPaT) is sent to auto\u00adma\u00adted vehicles.<\/p>\n

A MAP file is a digi\u00adtal image of the respec\u00adti\u00adve inter\u00adsec\u00adtion, in which rou\u00adte infor\u00adma\u00adti\u00adons are also stored. This enables auto\u00adma\u00adted vehic\u00adles to loca\u00adte them\u00adsel\u00adves at the inter\u00adsec\u00adtion and assign the valid signal image to the respec\u00adti\u00adve lane.<\/p>\n

The SPaT file (Signal Pha\u00adse and Timing) con\u00adta\u00adins the cur\u00adrent signal of a traf\u00adfic light, which can be trans\u00admit\u00adted digi\u00adtal\u00adly by the roadsi\u00adde unit. In addi\u00adti\u00adon to the visi\u00adble per\u00adcep\u00adti\u00adon by vehic\u00adle came\u00adras, a second red\u00adun\u00addant signal is thus available to the auto\u00adma\u00adted vehic\u00adles. This is nee\u00added, for exam\u00adp\u00adle, if the came\u00adra image can\u00adnot be reli\u00aded on in poor visi\u00adbi\u00adli\u00adty con\u00addi\u00adti\u00adons. Fur\u00adther\u00admo\u00adre, the SPaT file can be used to pro\u00advi\u00adde the vehic\u00adle with the pre\u00addic\u00adted remai\u00adning time of the signal, which can be used to adjust the dri\u00adving beha\u00advi\u00ador in the cour\u00adse of the inter\u00adsec\u00adtion approach.<\/p>\n

By trans\u00admit\u00adting both file types, the com\u00adplex situa\u00adti\u00adon of an inter\u00adsec\u00adtion is made com\u00adpre\u00adhen\u00adsi\u00adble to the auto\u00adma\u00adted vehic\u00adle and relia\u00adble and safe tra\u00advel across the inter\u00adsec\u00adtion is made possible.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

Cross-Territorial Test Field<\/h3>\n

Our test field covers both the urban area and the sur\u00adroun\u00adding regi\u00adon. This allows us to test our use cases across a wide ran\u00adge of traf\u00adfic situa\u00adtions and circumstances.<\/p>\n

The term \u201ccross-territorial\u201d impli\u00ades that seve\u00adral muni\u00adci\u00adpa\u00adli\u00adties or admi\u00adnis\u00adtra\u00adti\u00adve levels are invol\u00adved in the pro\u00adject. For TEMPUS it regards the City of Munich respon\u00adsi\u00adble for the urban area as well as the Bava\u00adri\u00adan Sta\u00adte Con\u00ads\u00adtruc\u00adtion Direc\u00adto\u00adra\u00adte respon\u00adsi\u00adble for the sur\u00adroun\u00adding area of Munich. As dif\u00adfe\u00adrent road types are assi\u00adgned to the two admi\u00adnis\u00adtra\u00adti\u00adve levels (for exam\u00adp\u00adle urban roads, fede\u00adral roads, high\u00adways), the use cases can be tes\u00adted under a wide varie\u00adty of traf\u00adfic situa\u00adtions and con\u00addi\u00adti\u00adons within the frame\u00adwork of TEMPUS. It is also cru\u00adcial for the crea\u00adti\u00adon of traf\u00adfic regu\u00adla\u00adti\u00adon stra\u00adte\u00adgies to clo\u00adse\u00adly coope\u00adra\u00adte with the aut\u00adho\u00adri\u00adties bey\u00adond the city boundaries.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
