Complementing technologies can be applied to road management to help reduce emissions and address environmental issues.
Travel is a significant contributor to carbon emissions and a major source of airborne particulates which can serious affect long-term health.
More efficient road management, using Advanced Traffic Management System (ATMS) technology, can help to smooth traffic flows and reduce vehicle emissions. ATMS and smart parking solutions integrated can be integrated and have a significant, positive effect on traffic and emissions levels.
Road User Charging (RUC)/tolling technology can also be used to manage demand for access to roads, introducing a dynamic pricing element which encourages road users to think about when they travel, and how.
More polluting vehicles can be charged more in order to deter their use/govern where they travel.
Funds raised by demand management schemes can subsidize public transport which, combined with smart parking solutions, gives travelers true choices in terms of reducing the environmental burden of their journeys.
In addition, specialist environmental sensors can be allied to ATMS and RUC solutions, providing real-time information on air quality and allowing decisions to be made on whether or not to allow vehicles access to certain areas, to increase the cost of access for certain types of vehicles, to reduce speed limits, and so on.
Policies exist in many locations which encourage non-vehicular travel such as cycling and walking. Bicycle and pedestrian detection technologies can be linked to environmental sensors to provide information on air quality and weather. This helps to encourage non-vehicular travel by reducing concerns over health and safety.
Weigh in Motion (WIM) technology can be used to identify heavy goods vehicles which are overweight, overloading their power-trains and so producing greater levels of carbon and particulates.
All of these technologies can be networked to create robust, coherent solutions to environmental issues in urban areas.
