The Helsinki Region Transport System Plan (HLJ) is prepared by HSL (Helsinki Region Transport, HRT). HRT plans and arranges public transport within its region and promotes its operational prerequi-sites, procures bus, tram, metro, ferry and commuter train services, approves the fare and ticket system for public transport and the ticket prices, manages the marketing and passenger information of public transport, and organises ticket sales and inspections. (HRT 2018)

HRT procures public transport servic-es within the area of its member munic-ipalities. Its members Helsinki, Espoo, Vantaa, Kauniainen, Kerava, Kirkkonum-mi and Sipoo as well as Siuntio and Tuusula which joined at the beginning of 2018. (HRT 2018) In recent years, HRT has emphasised the development of its trunk lines or trunk network in order to improve the attractiveness and ease of use of public transport. The trunk net-work is based on a heavy rail netnet-work of local trains and metros that is supple-mented by the trunk bus lines.

In recent years, HRT has empha-sised the development of its trunk lines or trunk network in order to improve the attractiveness and ease of use of public transport. The trunk network is based on a heavy rail traffic network of commuter trains and metros that is supplemented by the trunk bus lines.

The important long-distance railway stations are Helsinki, Pasila, Tikkurila and

Leppävaara. The central locations for long-distance bus traffic are the Kamppi bus station in Helsinki and Helsinki-Van-taa Airport. Park-and-ride car parks have been mainly set up in connection with the heavy rail traffic stations. (Helsinki Region Transport 2015)

5.1.2 Current road networks Road connections

Road traffic (freight and passenger traf-fic) from the Airport to the main roads runs along roads as Lentoasemantie, Terminaalitie, Ilmakehätie, Tietotie, Jun-kersintie and Kiitoradantie. Lentoase-mantie and Tietotie merge with Tikkuri-lantie to the south of the Airport. In the south, Lentoasemantie has an exit to Kehä III. In the east, Junkersintie con-nects to Tuusulanväylä. Kiitoradantie has an exit to Kehä III.

The traffic volumes are presented in the figure (Figure 5 21). In 2017, the average daily traffic volume on Termi-naalitie was 21,682 vehicles, of which heavy traffic accounted for 537 vehicles (2.5%). In 2017, the average daily traffic volume on Ilmakehätie was 16,528 ve-hicles, of which heavy traffic accounted for 502 vehicles (3%). In 2017, the ave-rage daily traffic volume on Junkersin-tie was 17,383 vehicles, of which heavy traffic accounted for 605 vehicles (3.4%).

In 2017, the average daily traffic volume on Kiitoradantie was 7,933 vehicles, of

which heavy traffic accounted for 313 ve-hicles (3.9%). In 2017, the average daily traffic volume on Tuusulanväylä, north of the intersection with Kehä III was 53,375 vehicles, of which heavy traffic account-ed for 1,722 vehicles (3.2%). In 2017, the average daily traffic volume on Kehä III was 92,910 vehicles, of which heavy traf-fic accounted for 7,929 vehicles (8.5%).

Road traffic in the Otaniemi region runs along Länsiväylä, Karhusaarentie and Kehä I.

The traffic volumes are presented in the figure (Figure 5 22). In 2017, the ave-rage daily traffic volume on Länsiväylä, east of Otaniemi, was 63,497 vehicles, of which heavy traffic accounted for 4,017 vehicles (6%). In 2017, the average dai-ly traffic volume on Länsiväylä, west of Otaniemi, was 48,770 vehicles, of which heavy traffic accounted for 1,423 vehicles (2.9%). In 2017, the average daily traffic volume on Karhusaarentie was 32,244 vehicles, of which heavy traffic account-ed for 2,558 vehicles (8%). In 2017, the average daily traffic volume on Kehä I was 26,978 vehicles, of which heavy traf-fic accounted for 1,536 vehicles (5.7%).

79 Railway connections

The railway connection closest to Hel-sinki-Vantaa Airport is the Ring Rail Line that runs in a tunnel below the Airport at a depth of approximately 40 metres. The stations at the Airport region are Aviapo-lis and Helsinki-Vantaa Airport.

Sea routes

Several shipping lanes managed by the Finnish Transport Agency and the Port of Helsinki run in the sea area near Koira-saari, Uppoluoto and the Ulkomatala and Hramtsow shoals. A 10.5-metre lane ma-naged by the Finnish Transport Agency (Record no. 4193/1042/2014) runs to the north of Koirasaari, at a minimum dis-tance of 500 metres. A 10.8-metre lane to the West Port of Helsinki (Record no.

506/1042/2012) runs to the east of Koi-rasaari, at a minimum distance of 3 kilo-metres. The lane ends at the West Port of Helsinki, in front of Jätkäsaari. The West Port lane also runs to the east of Uppo-luoto and Ulkomatala shoal. A 9.6-met-re shortcut lane for passenger traffic to Helsinki (Record no. 115/76/2000) runs to the south of Ulkomatala shoal, at a minimum distance of approximately 500 metres, and it is classified as a class 1 shipping lane for VL1 merchant shipping.

The lane connects to the Helsinki West Port lane. A 9.6-metre lane managed by the Finnish Transport Agency (Record no. LIVI/999/06.02.02/2015) terminating at West Port runs between Ulkomatala and the Hramtsow shoal. An 11-metre

lane managed by the Finnish Transport Agency (Record no. 3233/1042/2011) terminating at the Port of Vuosaari runs to the east of Hramtsow shoal, at a dis-tance of approximately 7 kilometres. The sea shipping lanes near the project area are shown in the figure (Figure 5-4).

A large number of ships operate on the Gulf of Finland each year. Shipping lanes with regular traffic cross each other near the alternative locations for the artificial islands to be constructed for the pur-poses of the project at a minimum dis-tance of some 500 metres. Most of the commercial traffic in the Gulf of Finland follows the Traffic Separation Scheme (TSS). Marine traffic in the Gulf of Finland is supervised by the marine traffic cen-tres in Helsinki, Tallinn and St Petersburg as part of the mandatory ship reporting system for the Gulf of Finland (GOFREP).

All ships with a gross tonnage (GT) above 300 are required to follow the system.

Analysing the data from the Automatic Identification System (AIS) provides more detailed information on the ship traffic crossing the Gulf of Finland. AIS is used for information exchange between ships as well as between ships and land sta-tions. The AIS system allows ships to see the positions, routes and speeds of other ships as well as the risks for collision.

The International Maritime Organisa-tion (IMO) has decided that all ships with a gross tonnage (GT) above 300 must be equipped with class A AIS transmitters by the end of 2004. However, military ships are the exception and the system is not required for them. In recent years, the completely voluntary AIS class B trans-mitters have become more common in smaller ships (less than 300 GT). (Ram-boll 2013)

The density of ship traffic on the near-est shipping lanes will be analysed and the detailed information will be present-ed in the environmental impact assess-ment report. The below figure (Figure 5-5) presents, by way of example, a map of the Gulf of Finland created in connec-tion with the Balticconnector natural gas

pipeline project in 2013, based on data from 2012 (Ramboll 2013).

The areas indicated in yellow have a low ship density, whereas in the green areas, the annual number of ships exceeds 1,500. The figure shows that the most part of ship traffic follows the Traffic Separation Scheme when arriving

82

in or departing the Gulf of Finland. Ship traffic density is also high to the east of the Balticconnector gas pipeline, which would also be the location of the artificial islands planned in this project.
