Putrajaya, a federal administrative centre, is facing traffic accidents and congestion problems. Realising that combating these two issues is very challenging, the relevant authority has embarked on ambitious safe system or also known as Putrajaya Zero Fatalities Vision and explicit goal on 70:30 for public transport and private vehicles share in the core precincts. In its efforts to achieve the aim, numerous projects such as upgrading the transport facilities and provide new infrastructure have been carried out. Various studies were also conducted to understand the underlying factors influencing the mode choices and willingness to shift to public transport under different intervention measures. However, little is known about the consequences of mode shift on the transport network system. This study is to close the gap by exploring the risk of accidents and travel demand on different modes.

Transport planning model EMME/3 is proposed to be used in modelling the accident risk on Putrajaya network system. The software is able to simulate the integrated multimodal assignment, the mobility or exposure on each link on the network. With the development of base model, different scenarios under various intervention measures or policy testing can also be tested. Based on the results from the models, the most effective policy can be identified for the improvement of transportation system in that area.
