Study on effect of flow forecasting error on traffic control performance
Journal Title: Science Paper Online - Year 2008, Vol 3, Issue 10
Abstract
With many flow forecasting algorithm occur, there are few research on flow forecasting error influence on traffic control parameters and performance. So according to data of Jiangxi Road in Qingdao city, this paper analyses the feasibility and application of conventional linear forecasting model. This paper gets predicted error of the precision and estimates model’s interference on flow rate and cycle length, then evaluates the change on traffic control performance including average delay and capacity. In the analysis beforehand taking data smoothing can reduce forecasting error and lessen its effect on control parameters and performance. Finally the result shows that while forecasting error of the linear forecasting model is about 10% that causes cycle length 2% of forecasting error and the error green is in 2 second, average delay and capacity are less than 5%. Therefore the conventional linear model is feasible in practical signal timing and can simplify the complexity of system to improve performance and efficiency.
