Analysis of Microscopic Behavior in Ant Traffic to Understand Jam-free Transportation

Analysis of Cooperative Perception in Ant Traffic and Its Effects on Transportation System by Using a Congestion-Free Ant-Trail Model

“…The observation indicates that assumed σ sat in the modelling is misleading and is much higher than the σ sat representing real AT. The above analysis, along with previous findings in [29,30] indicates that considering pheromone chemoreceptors' evolutionary optimization, the saturation pheromone concentration for AT might be dependent on r e and might be equal to the σ X (t M ) in the aggregation scenario. We argue that, as the analysis indicates that the σ X (t) never increase above the σ X (t M ) in aggregation scenario, the ants do not need an evolution of chemoreceptors to differentiate pheromone higher than the σ X (t M ).…”

“…It also explains different aspects of the functional communication system in AT, including the sensitivity of the information to different traffic scenarios, and the relation between the sensitivity and resource management in AT. Moreover, the analysis explains and give us possible reasoning about findings from [25,29], which indicates that ants on a trail might have optimized trail pheromone evaporation rate (r e = 0.02) to function in an active trail state for foraging efficiency.…”

“…For the readers' convenience, we briefly re-introduce ATM from [25,29,30] here. Individual ants in AT cooperate to understand traffic scenario through CP&C. In AT, individual ants' travelling decisions depend on traffic perception through the chemical substances known as pheromones [18,19].…”

“…Although natural ATs are open boundary systems, as we wanted AT simulations to form over a period of time without any external interference, we used the periodic boundary condition. Simultaneously, by using a trail of length 1000 cells, we ensured that the trail was long enough to make any ant's self-interaction effects negligible, which arise under the periodic boundary condition with a short track [25,29]. Table 1.…”

“…Hence, it needed to be improved and analyzed while considering [ 21 ]’s findings. Therefore in [ 25 , 29 , 30 ], we presented an improved model of AT with a new perspective on the mechanism of congestion-free AT in light of new findings from [ 21 ]. Similar to [ 23 , 24 ], the model in [ 25 , 29 , 30 ] also assumes that ants use CP&C through chemotaxis for traffic management on AT.…”
