Accessibility to an airport is essential for air travellers since late arrival will result in missing a flight and financial loss. During the peak period, arrival at Leeds Bradford International Airport (LBIA) tends to be more vulnerable due to delays and queues at particular junctions in the road network. To improve the accessibility during this period, several improvements in the road network have been carried out and simulated using SATURN (Simulation and Assignment of Traffic in Urban Road Networks). The results show that the improvements in the network managed to reduce the generalised cost of travel because it has brought benefits for air travellers. This study found that junction improvement has brought monetary benefits equal to 153.67 pounds from 261 trips to LBIA which occurred during the morning peak period (08.00-09.00 AM).
