An Improved Car-Following Model in Vehicle Networking Based on Network Control

Table 1

The main variables for the model application.

Variable	Meaning
𝑣𝑓1	Ideal free flow speed in traditional conditions
𝑣𝑓2	Ideal free flow speed in vehicle networking conditions
𝑄𝑚2	Road capacity in vehicle networking conditions
𝐷1	Average distance between vehicles in single lane, in traditional conditions, when reaching the blocking density. Unit: m
𝐷2	Average distance between vehicles in single lane, in vehicle networking conditions, when reaching the blocking density. Preceding analysis shows 𝐷2≈0
𝐿	Average length of car (m)
𝐾𝑗1	Traffic density maximum in traditional conditions, block density
𝐾𝑗2	Maximum density in vehicle networking conditions, blocking density
𝑄𝑚1	Road capacity in traditional conditions
