Abstract
Dit rapport beschrijft een quick scan van de
milieu-effecten van beleidsvarianten uit de Nota Mobiliteit om de
bereikbaarheid en betrouwbaarheid van het wegennet te verbeteren. De
belangrijkste conclusies zijn als volgt. De twee prijsvarianten uit de Nota
Mobiliteit leveren bereikbaarheidswinst op en in beperkte mate milieuwinst.
De vormgeving van de variabilisatie-variant is van grote invloed op de
uiteindelijke omvang van de milieuwinst. Daarnaast wil het rijk investeren
in het onderliggende wegennet als dit een oplossing biedt voor
bereikbaarheidsproblemen op snelwegen en als het kosteneffectief is. Het
verdient aanbeveling om in de besluitvorming over investeringen in het
onderliggende wegennet ook expliciet rekening te houden met de ruimtelijke,
milieu en sociale effecten van deze investeringen om mogelijke afwenteling
van problemen naar het onderliggend wegennet te voorkomen. In de uitwerking
van de Nota Mobiliteit in de plannen van de decentrale overheden lijkt het
verder van belang aandacht te besteden geluidsknelpunten. Het aantal
geluidsknelpunten langs provinciale wegen neemt zonder aanvullende
maatregelen fors toe. Tenslotte is nader onderzoek aan te bevelen naar de
prioritering van bouwprojecten binnen de onderzochte investeringspakketten
in combinatie met prijsbeleid. Goed gekozen combinaties van beprijzen en
benutten kunnen de noodzaak tot aanleg van nieuwe traces mogelijk beperken,
negatieve effecten op natuur/landschap beperken, en hogere netto
maatschappelijke baten opleveren.
This report documents an analysis of the environmental impacts of policy proposals taken up in the new Dutch National Transport Policy Document for improvement of accessibility and reliability of the main motorway network in the Netherlands. Major conclusions drawn from this analysis are that pricing policies proposed in the policy document effectively improve accessibility and reduce environmental impacts due to road traffic. The size of environmental benefits of the proposed kilometre charge, however, is determined by the final design of the policy measure. Furthermore, the policy document proposes secondary road expansion be state-funded if this would mean a contribution to reducing congestion on the main motorway network. However, before state-funding is decided, more research on the costs and benefits of secondary road network expansion is necessary, including the transfer of environmental and social problems from the main motorway network to the secondary road network. Furthermore, it would seem important to have local and regional authorities pay attention to noise hotspots in their transport policy development, since without additional measures, the number of noise hotspots along secondary roads will sharply increase. Finally, further research on giving priority to infrastructure projects within the proposed infrastructure investment in combination with pricing policies packages is recommended. Combinations of pricing and expanding existing infrastructure may reduce the need to construct new motorway links, reduce negative impacts on nature conservation areas and rural landscapes, and result in higher net economic benefits.
