Autostrada A8 Târgu Mureș-Iași

[bim14]

Odata construita, autostrada va aduna traficul de pe aproape toata Moldova plus Basarabia, cel putin asa apare prin documentele oficiale. Unde mai pui ca zeci de mii de cetateni maghiari isi petrec vacantele in Harghita si Covasna, deci pana la Gheorgheni sigur or sa prefere sa vina pe autostrada.
Nu mai zic de tot potentialul de dezvoltare pe care il va oferi atat Moldovei cat si Basarabiei. Acum, pana va fi gata autostrada prin 2050, probabil mare parte din productia europeana va fi mutata in China/India.

^imho, lucrurile vor sta exact invers: pana in 2050, o mare parte din industriile delocalizate in China/India/Asia se vor fi relocat in Europa (de Est). Inca un argument ptr a nu ne scumpi acum la tarate: autostrazi HP, cai ferate la standarde de sec xx, samd.

Traseul e calibrat si pus pe harta API. Daca mai doriti ceva la structuri, mai tin documentatia pentru cateva zile si pot sa postez planse .

"Bidirectional" înseamnă Cut&cover.
"Unidirectional" doua galerii forate.
Evident, la cut&cover nu merita sa sapi doar pentru HP.

Unidirecțional: doar un sens al autostrăzii trece prin tunel.
Bidirecțional: ambele sensuri trec prin tunel.

Din Memoriul Tehnic eu înțeleg că nu e nimic cut&cover.

DIRECTIVE 2004/54/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL

of 29 April 2004

on minimum safety requirements for tunnels in the Trans-European Road Network


ANNEX I

Safety measures as referred to in Article 3

1.3.  Traffic volume   

1.3.1. Where "traffic volume" is mentioned in this Annex, it refers to the annual average daily traffic through a tunnel per lane. For the purpose of determining the traffic volume, each motor vehicle shall be counted as one unit.

1.3.2. Where the number of heavy goods vehicles over 3,5 t exceeds 15% of the annual average daily traffic, or seasonal daily traffic significantly exceeds the annual average daily traffic, the additional risk will be assessed and taken into account by increasing the traffic volume of the tunnel for the application of the following paragraphs.


2.  Infrastructure measures

2.1.  Number of tubes and lanes   

2.1.1.The main criteria for deciding whether to build a single or a twin-tube tunnel shall be projected traffic volume and safety, taking into account aspects such as the percentage of heavy goods vehicles, gradient and length.

2.1.2. In any case, where, for tunnels at the design stage, a 15-year forecast shows that the traffic volume will exceed 10 000 vehicles per day per lane, a twin-tube tunnel with unidirectional traffic shall be in place at the time when this value will be exceeded.

2.1.3. With the exception of the emergency lane, the same number of lanes shall be maintained inside and outside the tunnel. Any change in the number of lanes shall occur at a sufficient distance in front of the tunnel portal; this distance shall be at least the distance covered in 10 seconds by a vehicle travelling at the speed limit. When geographic circumstances prevent this, additional and/or reinforced measures shall be taken to enhance safety.
