Highways England have been undertaking extensive research into potential air quality solutions for the strategic road network that could reduce levels of NO2. They have explored a wide range of ideas including the effectiveness of different traffic management options, understanding obstacles to greater use of electric vans on the network and different types of barrier design.<\/p>
<\/p>
Based on all their research, they have robust evidence that a 9.5 metre high barrier can help reduce levels of nitrogen dioxide behind the barrier and have developed a programme to identify potential sites around the network.<\/p>"} , "answeringMember" : {"_about" : "http://data.parliament.uk/members/3991", "label" : {"_value" : "Biography information for Jesse Norman"} } , "answeringMemberConstituency" : {"_value" : "Hereford and South Herefordshire"} , "answeringMemberPrinted" : {"_value" : "Jesse Norman"} , "dateOfAnswer" : {"_value" : "2018-11-19", "_datatype" : "dateTime"} , "isMinisterialCorrection" : {"_value" : "false", "_datatype" : "boolean"} , "questionFirstAnswered" : [{"_value" : "2018-11-19T11:01:02.707Z", "_datatype" : "dateTime"} ]} , "answeringDeptId" : {"_value" : "27"} , "answeringDeptShortName" : {"_value" : "Transport"} , "answeringDeptSortName" : {"_value" : "Transport"} , "date" : {"_value" : "2018-11-09", "_datatype" : "dateTime"} , "hansardHeading" : {"_value" : "Motor Vehicles: Exhaust Emissions"} , "houseId" : {"_value" : "1"} , "legislature" : [{"_about" : "http://data.parliament.uk/terms/25259", "prefLabel" : {"_value" : "House of Commons"} } ], "questionText" : "To ask the Secretary of State for Transport, what progress Highways England is making on reducing levels of NO2 on the strategic road network.", "registeredInterest" : {"_value" : "false", "_datatype" : "boolean"} , "tablingMember" : {"_about" : "http://data.parliament.uk/members/4637", "label" : {"_value" : "Biography information for James Frith"} } , "tablingMemberConstituency" : {"_value" : "Bury North"} , "tablingMemberPrinted" : [{"_value" : "James Frith"} ], "uin" : "189797"} , {"_about" : "http://data.parliament.uk/resources/1003649", "AnsweringBody" : [{"_value" : "Department for Transport"} ], "answer" : {"_about" : "http://data.parliament.uk/resources/1003649/answer", "answerText" : {"_value" : "
The Department for Transport published the outputs of the Transport Energy Model in July 2018 alongside the Road to Zero strategy.<\/p>
<\/p>
The model estimates the average tailpipe emissions of air pollutants, the greenhouse gas emissions and the energy consumption of a range of fuel and powertrain options for cars, vans, buses and heavy goods vehicles (HGVs) over the period to 2050.<\/p>
