Progression bandwidth maximization is one of the most important signal coordination strategies for urban arterial signal control. MAXBAND and MULTIBAND have implemented a weighting factor that is capable to adjust the bandwidth according to unbalance bandwidth demands in a two-way bandwidth maximization problem. However, the maximum bandwidth solution may not be achieved with certain values of weighting factors. Therefore, it might require users to have a good idea about what weighting factor to use in order not to compromise the total bandwidth. In this paper, we proposed a new two-way bandwidth maximization model that not only maximizes the total bandwidth but also introduces a bandwidth proration impact factor. This impact factor allows the user to control the importance of satisfying the bandwidth demand ratio. Numerical examples have demonstrated that the new model has the following advantages: (a) when two-way progressions are difficult to achieve, the model first guarantees maximum total bandwidths and then automatically prorates the bandwidth fully to the direction with higher traffic demand; (b) when two-way progressions could be achieved, the model not only guarantees maximum total bandwidth but automatically prorates the bandwidth in a ratio as close as possible to the ratio of bandwidth demands.
