Abstract: Urban traffic congestion is a chronic problem faced by many cities. It isessentially inefficient infrastructure use which results in increased vehiclefuel consumption and emissions. This in turn adds extra costs to commuters andbusinesses. Addressing this issue is therefore of paramount interest due to theperceived dual benefit. Many technologies were and are being developed. Theseinclude adaptive traffic signals, dedicated lanes, etc. This paper presents asimple platooning algorithm that maintains relatively small distances(pre-specified time gap) between consecutive vehicles to enhance mobility,increase transportation capacity and ultimately reduce travel costs. Severaldynamic and kinematic constraints governing the motion of vehicles are alsoaccounted for. These include acceleration, velocity, and distance constraints.This developed logic was tested on highways that traverse the downtown area ofLos Angeles. Depending on the market penetration rate of connected automatedvehicles versus non-connected automated vehicles, a reduction in travel time,delay and fuel consumed across the city can be observed. Vehicles are expectedto reach their destination in less travel time, delay and consumed fuel. Thereduction percentages range from 0 to 5 percent, 0 to 9.4 percent, and 2.58 to8.17 percent, respectively.
