|Abstract:||The concept of Environmental Adaptation seeks to create an environment that manages friction and impact on certain types of transport corridors (Type II). Such corridors frequently contain a mix of issues relating to pedestrian safety, business activity, convenience, amenity, site access, parking, public transport and the movement of motor vehicles. While the concept has been applied in some jurisdictions in Australia, its use is still not widespread as it involves a highly integrated strategic approach involving agreement between many stakeholders. However, where implementation has occurred, it has been very successful in introducing safety and in some cases the regeneration of business activities. An opportunity existed to apply the concept of Environmental Adaptation to an area of high pedestrian activity at a collector road on the Khon Kaen University Campus in Thailand. The area was problematic due to a large retail centre constructed next to the collector road attracting many pedestrians from campus buildings across the road including the Library, Faculty of Science and Faculty of Agriculture buildings. Although a pedestrian crossing was present, the existing infrastructure did little to reduce conflicts between pedestrians and traffic and public transport stops added to the complexity. It was decided to construct a distinct zone in which pedestrians could safely perform their crossing activities according to the principles of Environmental Adaptation. Quantifying the impact of such alterations is a difficult task and a novel approach using microsimulation modelling was used to provide visualisation and output for both pedestrians and traffic. A before and after scenario were modelled and travel times and delays were established for both motorists and pedestrians. Extensive traffic and pedestrian surveys were conducted to provide the basis for the modelling. Vehicle fleet characteristics had to be established and special pedestrian classes were also established so that they could be modelled in a simplistic manner. The microsimulation modelling was used along with artist impressions to promote the concept and conduct stakeholder consultation. This was an important step as the Environmental Adaptation concept had never been used before in this region of Thailand. This paper describes the concept and modelling concerning the implementation of the scheme.|
