The Ipswich Strategic Plan Area (ISPA) incorporates Suffolk County Council, Ipswich Borough Council, Babergh District Council, Mid Suffolk District Council and East Suffolk Council (in relation to the area of the former Suffolk Coastal District). The ISPA Board of members representing the five authorities provides a forum in which the five local authorities can work together to develop, promote and deliver their vision for the Ipswich Strategic Planning Area, recognising Ipswich and neighbouring communities as a major economic growth area within the Greater Ipswich sub region, County of Suffolk and New Anglia Local Enterprise Partnership area. Working together enables them to co-operate as local planning authorities on the preparation and monitoring of their Local Plans and share relevant evidence and intelligence. 1.1.2. To understand the cumulative impact on the highway network of growth updated in the local plans to 2036, assessments were undertaken using the Suffolk County Transport Model (SCTM), which is a strategic highway model built in Saturn that has been calibrated and validated to reflect traffic conditions for a base year of 2016. The SCTM is a network wide model for assessing traffic schemes and developments, and as such it is appropriate to use as a tool for assessing network wide impacts. 1.1.3. An initial modelling report, January 20191, identified impacts on the highway network associated with the model run for 2036, incorporating Suffolk Coastal District Council and Ipswich Borough Council’s Preferred Options and Babergh and Mid Suffolk District Council’s development options. This model
