Table 2

Parameters, acronyms, and scenarios.

Parameters

Number of vehicles queuing at the DI at the end of the first green signal
Number of vehicles queuing at the DI at the end of the second green signal
Jam density per lane
Total length of the link
Distance between the delivery area and the upstream intersection
Distance between the delivery area and the downstream intersection
NMaximum number of vehicles that can be discharged during a cycle
Maximum number of vehicles that can be discharged at the intersection during a cycle by the lanes that are not blocked
, Maximum number of vehicles that could be accommodated in the distance of in the lane with the delivery area
SSaturation flow rate per lane
Length of the signal cycle
Minimum distance value of that guarantees that no traffic spillover is caused to other links
Minimum distance value of that guarantees that no traffic spillover is caused to other links
Length of the green signal
Green time for the UI and the DI
Number of lanes per direction
Traffic flow arriving from upstream
Maximum traffic demand volume with which DDPS are possible
Distance needed for each delivery space
Factor that represents the merge effect of the vehicles on the shoulder lane to the immediate next lane
Transformation of the parameter to simplify the notation
