GESTA - Road Management through a tariff which maximises the social benefit for sustainable mobility
Overview
Background & policy context:
The GESTA project analysed the implementation of several measures of "value and service pricing" which allowed a more efficient use of the actual capacity of interurban roads.
Objectives:
The main aim of this project was the analysis of measures of "value and service pricing" for more efficient use of interurban roads.
Under this approach, the social welfare function would be defined for different scenarios. Furthermore, their respective socio-economic effects and a set of compensation measures to reinvest incomes and decrease initial impacts which will cause these kinds of measures on the different groups of people will be formulated.
Methodology:
The research activities were articulated in five fundamental phases:
A) Analysis of the value pricing and service pricing, as well as determination and average of social and road transport costs for goods and passengers.
B) Problem approach: This phase had several objectives:
- to configure GESTA network in the interurban roads,
- to structure the social welfare function
- to determine the different restrictions which are linked to the different alternatives of value and service pricing.
C) Optimisation of the social welfare. Several alternatives of "value pricing" were planned, which allowed optimisation of the social welfare function obtained in the former phase.
D) Assessment of the proposals: the different pricing alternatives are evaluated through operational indicators, economical-financing and social, in such a way that the alternative that will fit better to the evaluated network in phase 1 could be selected through a DAFO matrix.
E) Model implementation. Analysing the results of the former phases which allows definition of the progressive form and phasing of the application of the selected pricing system.
