Furthermore, the flow rate is formulated by the average time headway: \(q\left(flow \,rate\right)=1/\overline{h }(time \,headway)\). Figure 3 provides a visual representation of vehicular movement westbound across different frames or time intervals. The horizontal axis displays the sequence...
In order to eliminate the influence of different dimensions, the data are normalized, and the normalization formula is shown in Eq. (16). $$Q_{nor} = \frac{Q - mean(Q)}{{std(Q)}}$$ (16) where \(mean(Q)\) represents the mean of sequence data and \(std(Q)\) represents ...

The calculation formula of the pollution source intensity can be described with Equation (10). Single vehicle exhaust emissions have a strong relationship with their speed. In this study, the method of calculating the average emission rate in a certain driving speed range proposed by Zhang et al...
The formula is as follows: 𝐴𝐵𝑋=𝐴𝑋+𝐵𝑋ABX=AX+BX (2) 𝐵𝑋=(𝐵𝑋𝑎𝑑𝑑+𝐵𝑋𝑚𝑢𝑙𝑡·𝑅𝑁𝐷1𝑛)·𝑣−−√BX=(BXadd+BXmult·RND1n)·v (3) 𝑣=min(𝑣𝑛,𝑣𝑛+1)v=min(vn,vn+1) (4) 𝐵𝑋BX denotes the additional...
In other words, if the previous arrival of the packet was at t1 and the current time is t, the bucket is updated with t-t1 worth of bytes based on the token arrival rate. Note: A traffic policer uses burst values specified in bytes, and the previous formula converts from bits to ...
The transfer rate in a transponder is usually higher that the required of a multiple IP flow, just to avoid any kind of bottleneck. The requirements in a type of network such as this are: (1) the use of the shortest path for the formation of the light tree, (2) the relation of an...
Allsop’s formula (6.31)D=910⋅r22⋅C⋅1−ρ+α22⋅λ⋅1−α Example 6.3 The cycle length at the signalized intersection equals 80 s. The considered approach has the saturation flow of 2200 (veh/h), the green time duration of 30 s, and flow rate of 600 (veh/h). Calcula...
When building a network for IP video surveillance systems, one of the important indicators of a network is the value of the maximum flow generated by all video cameras in the system. The flow rate of each camera depends on its resolution, on the compression codecs used, the selected frame ...
