potential short term and longer term impacts of introducing a road bridge link to the Isle of Wight The Isle of Wight is situated between the Solent and the English Channel is roughly rhomboid in shape and covers an area of 150 sq mi 380 km2 Slightly more than half mainly in the west is designated as the Isle of Wight Area of Outstanding Natural Beauty The island has 100 sq mi 258 km2 of farmland 20 sq mi 52 km2 of developed areas and 57 miles 92 km of coastline Its landscapes are diverse leading to its oftquoted description as England in miniature In June 2019 the whole island was designated a UNESCO Biosphere Reserve recognising the sustainable relationships between its residents and the local environment The four stages or four steps transportationland use model follows a sequential procedure Trip Generation For each discrete spatial unit it is estimated the extent to which it is an origin and destination for movements The output is usually the number of trips generated and attracted by a given spatial unit Trip Distribution Commonly a spatial interaction model estimates movements flows between origins and destinations and which can consider constraints such as distance The output is a flow matrix between spatial units Modal Split Movements between origins and destination are then disaggregated by modes This function depends on the availability of each mode their respective costs and also social preferences Traffic Assignment All the estimated trips by origin destination and mode and then loaded on the transportation network mainly with the consideration that users want to minimize their travel time or have to flow through existing transit networks If the traffic exceeds the capacity of specific transport segments which is often the case congestion occurs and negatively affects travel time This in turn through a feedback process may influence trip generation and distribution This procedure is See Answer
