An Improved Algebraic Method for Transit Signal Priority Scheme and Its Impact on Traffic Emission

Table 2

Calculation rule of split loss.

Ahead of nearest ideal intersection		Behind of nearest ideal intersection
Front-loss 𝐿𝑓	Back-loss 𝐿𝑏	Front-loss 𝐿𝑓	Back-loss 𝐿𝑏
50∗𝑑/𝑎+(50−𝜆)/2	−50∗𝑑/𝑎+(50−𝜆)/2	−50∗𝑑/𝑎+(50−𝜆)/2	50∗𝑑/𝑎+(50−𝜆)/2

Where 𝑑 is the distance between the intersection and its nearest ideal intersection; 𝑎 is the ideal intersection interval; 𝜆 is the split of the intersection, 𝜆∈(0,1).
