Scheme Design

The original Trondheim toll ring system, implemented in 1991, went through two major revisions. Firstly, in 1998 some charging points were relocated and 6 more were added, making it into a multi zone system comprising 18 stations. A second revision of the scheme layout was made in November 2003 by adding an inner CBD (city centre) ring. This increased the number of stations to 24. 

On 30 December 2005 the urban tolling system in Trondheim was turned off, nine months before the legal concession period of 15 years had elapsed. The local decision makers chose to stick to this date, even if implementation was delayed from January to October 1991. Trondheim was the third city in Norway to introduce a toll ring, following the examples of Bergen from 1986 and Oslo from 1990. So, while Bergen and Oslo have decided to continue their charging systems to finance new transport projects, Trondheim became the first Norwegian city to discontinue charging and dismantle their charging equipment.


The 1991 Toll ring The Trondheim scheme was unique in three aspects when it was introduced in 1991, (i) it was fully electronic with non-stop toll lanes from the start, (ii) it had time-differentiated charges, and (iii) only a payment per each trip option was available. The figure below shows key aspects of the toll ring. 11 new automatic toll stations were built, of which only one had additional manned operation. In addition, one existing manned motorway toll station to the east at Ranheim completed the ring. 21 of the 35 lanes leading in to the toll stations were non-stop lanes for tag holders.




The 1998 Zone Based

Tolling Scheme In June 1996, the City Council in Trondheim decided on a revised toll charging scheme. This zone-like system was fully implemented during the first months of 1998 (figure belowTwo main objectives motivated the revision of the single cordon scheme: Firstly, more revenue was needed to fulfil the transport investment plans. Secondly, a more “equitable” scheme was called for (interpreted as a system charging a higher portion of the motorists). To some extent, the revised system was designed to provide daily service facilities inside each zone. The revised fee structure included a raise in the basic charge from 10 to 12 NOK1] (1.25€ to 1.5€), extended opening hours from 5 to 6 pm, and a lowering of the maximum number of charged crossings per month from 75 to 60.



The 2004 Extended Zone

Based Tolling SchemeA second and final extension involving six additional stations closer to the city centre came into operation 1 November 2003. The basic charge level had already been raised from NOK 12 (1.5€) to NOK 15 (1.9€) on 26 February 2001. With a typical discount of 30-40 % for tag holders, this implied a price per passage of around 1.2€. The layout of the scheme which now consisted of 24 stations (or strictly speaking 26 if stations located very close together to the south are counted separately) and 59 payment lanes is shown in the next figure.




The motivation for the final revision was to cover cost overruns on a remaining highway construction project, and this solution was preferred by the politicians rather than to run the scheme for the full 15 year period until 1 October 2006, or to extend payment periods to cover evenings and weekends. Prices per passage for light vehicles during the last years of operation are shown in the t able below. Heavy vehicles (gross weight more than 3.5 tons) always paid twice the amounts charged for light vehicles. Disabled drivers, electric powered cars and public utility vehicles were exempted. The one hour rule was always in force: No vehicle was charged for more than one crossing within an hour. Also, a maximum limit of 60 chargeable crossings within a month applied.
