Passenger car equivalents for urban roads using average time headway of car following conditions [PDF]

Advances in Mechanical Engineering, 2019
Passenger car equivalents are used to calculate capacity and evaluate service level of urban roads. This article uses the average time headway of different car following conditions to replace the total average time headway of road vehicles, and the proportion of large vehicles to improve the headway method.
