# Effect of Adaptive and Cooperative Adaptive Cruise Control on Throughput of Signalized Arterials

## TL;DR

This study uses simulation to assess how adaptive cruise control (ACC) and cooperative ACC (CACC) vehicles affect intersection throughput and urban mobility, showing significant benefits with minimal infrastructure changes.

## Contribution

It provides new insights into the impact of ACC/CACC vehicles on traffic flow and throughput at signalized intersections through detailed simulation analysis.

## Key findings

- CACC vehicles increase intersection throughput.
- Higher ACC/CACC proportions reduce travel time variability.
- Significant mobility benefits observed with minimal infrastructure changes.

## Abstract

The paper evaluates the influence of the maximum vehicle acceleration and variable proportions of ACC/CACC vehicles on the throughput of an intersection. Two cases are studied: (1) free road downstream of the intersection; and (2) red light at some distance downstream of the intersection. Simulation of a 4-mile stretch of an arterial with 13 signalized intersections is used to evaluate the impact of (C)ACC vehicles on the mean and standard deviation of travel time as the proportion of (C)ACC vehicles is increased. The results suggest a very high urban mobility benefit of (C)ACC vehicles at little or no cost in infrastructure.
