Intersections are the bottlenecks of the urban road system because an intersection’s capacity is only a fraction of the vehicle flows that the roads connecting to the intersection can carry. The saturation flow rate, and hence the capacity, can be doubled if vehicles can cross intersections in platoons rather than one by one as they do today. Platoon formation is enabled by connected vehicle te...

Abstract—Present study is carried out on six lane divided urban arterial road in Patna and Pune city of India. Both the road having distinct differences in terms of the vehicle composition and the road side parking. Arterial road in Patan city has 33% of non-motorized mode, whereas Pune arterial road dominated by 65% of Two wheeler. Also road side parking is observed in Patna city. The field st...

Vehicle platoon is one of important techniques both for improving the traffic safety and for increasing the traffic network capacity. Vehicle platoon system allows vehicles to drive at the same velocity and to accelerate or brake simultaneously. In this study, we will present the velocity control algorithm of the vehicles in the vehicle platoon and then, apply it to the velocity control of the ...

The Team Orienteering Problem (TOP) is defined as to find a set of vehicle walks such that the total collected reward received from visiting a subset of customers is maximized and the length of each vehicle walk is restricted by a pre-specified limit. The team orienteering problem with capacity constraint and time window(TOPCT) is an extension of the TOP where each customer has a demand and a t...

We consider the Capacitated Traveling Salesman Problem with Pickups and Deliveries (CTSPPD). This problem is characterized by a set of n pickup points and a set of n delivery points. A single product is available at the pickup points which must be brought to the delivery points. A vehicle of limited capacity is available to perform this task. The problem is to determine the tour the vehicle sho...

The Vehicle Routing Problem with Time Windows (VRPTW) is currently the focus of very intensive research, and is used to model many realistic applications. The overall objective is to serve a set of customers at minimum cost with a fleet of vehicles of finite capacity housed at a central depot. The route of each vehicle starts and ends at the depot. Also, each customer has a known demand (i.e. s...

Real-world distribution problems raise some practical considerations usually not considered in a realistic way in more theoretical studies. One of these considerations is related to the vehicle capacity, not only in terms of cubic meters or weight capacity but also in terms of the cargo physical arrangements. In a distribution scene, two combinatorial optimization problems, the Vehicle Routing ...

Sustainability is a monumental issue that should be considered in designing a logistics system. In order to incorporate sustainability concepts in our study, a waste collection problem with economic, environmental, and social objective functions was addressed. The first objective function minimized overall costs of the system, including establishment of depots and treatment facilities. Addressi...

This paper proposes a new theory to account for the effects of underload on performance. Malleable attentional resources theory posits that attentional capacity can change size in response to changes in task demands. As such, the performance decrements associated with mental underload can be explained by a lack of appropriate attentional resources. These proposals were explored in a driving sim...
