This is a condition index number which is derived by taking into consideration main defect types like cracking, LPV (a measure of the ride quality), rutting, and the use of algorithms results in a condition index number for each section of the road. A weighted average is then calculated for each category of road. The lower the number the better condition the roads are in.

Environmental Issues for GTP Area • There are a number of SSSI’s in the area. The condition of these SSSI’s is generally favourable or unfavourable recovering but there is one SSSI in unfavourable condition which is not improving. This is Moor Mill Quarry West SSSI. The lack of improvement in this SSSI is an environmental issue in the area. • The number of children killed or seriously injured and the total number of people killed or seriously injured in road traffic accidents have both decreased on a countywide level. However, when looking at rates by district for the number of people killed or seriously injured, Three Rivers, Dacorum and St Albans have seen an increase in KSI numbers in 2018. • The percentage of all trips under 3 miles by cycling has decreased again to 2% from 2.4% on a countywide scale. The low prevalence of cycling means that encouraging cycling is an issue for all regions in Hertfordshire. • Hertfordshire still has AQMAs all over the county with 17 HCC AQMA’s and 11 Highways England. 12 of these are within the GTP area therefore air quality is an environmental issue. • The County Council have set a new target for carbon emissions (Reduce carbon emissions by 80% from 2012/13 baseline by 2025 (net zero ambition in long term) and St Albans have nearly double the emissions than the County average. Therefore C02 emissions are an environmental concern for the GTP area. • Bus punctuality remains low for the County. Improving the provision of passenger transport remains an issue for all regions in Hertfordshire. • There are 35 scheduled monuments, 8 registered parks and gardens and 1156 listed buildings in the GTP area. Preservation of these is an issue for consideration.
