Capacity, demand, and vehicle based emissions reduction strategies are compared for several pollutants employing aggregate US congestion and vehicle fleet condition data. We find that congestion mitigation does not inevitably lead to reduced emissions; the net effect of mitigation depends on the balance of induced travel demand and increased vehicle efficiency that in turn depend on the polluta...

Population in cities is increasing very rapidly and hence demand of utility commodities is also increasing day by day. There is a need for the fleets of vehicles to deliver goods and material from distribution centres to local consumer locations within optimal travel distance and time. In this study, the above transportation problem have been tackled by solving the vehicle routing problem for t...

A model is provided to capture capacity phenomena in passenger traffic assignment to a transit network. These pertain to the interaction of passenger traffic and vehicle traffic: vehicle seat capacity drives the internal comfort, vehicle total capacity determines internal comfort and also platform waiting, passenger flows at vehicle egress and access interplay with dwell time, dwell time drives...

We study the feasibility of using electric vehicles in online, high-capacity ridepooling systems. Prior work has shown that online algorithms perform well for centrally-controlled, ridepool First, we propose a mixed integer linear program to expand past on vehicle fleets with objective scheduling charging maintain sufficient fleet sizes at various times day. Then show faster, scalable algorithm...

Most of today’s ADASs rely on the data of local perception sensors. With the introduction of Vehicle-to-X (V2X) communication, the perception range of next generation vehicles will be extended even further. In addition to the introduction of local perception sensors in Veins, we present ArteryLTE, a holistic simulation environment for using the vehicle position data from the microscopic traffic...

Electrical system capacity determination for conventional vehicles can be expensive due to repetitive empirical vehicle-level testing. Electrical system modeling and simulation have been proposed to reduce the amount of physical testing necessary for component selection [1, 2]. To add value to electrical system component selection, the electrical system simulation models must regard the electri...

This paper addresses the problem of constructing plans and schedules for resources that must obey spatial constraints in addition to time and capacity constraints. Spatial constraints are relevant in environments that involve mobile resources whose movements must be coordinated to avoid collisions and near-misses. In air-campaign planning, for example, aircraft are allocated to missions that mu...

In this paper, the frequency reuse and the distributed dynamic channel assignment for microcellular networks are studied. We show that it is possible to use carriers with violation to the frequency reuse pattern with an insignificant degradation of the quality of service. As a result, a new family of distributed dynamic channel assignment algorithms is presented: the DDCA with violation to the ...

As the number of automobiles increases, the task of providing parking lots to accommodate more vehicles becomes very difficult and challenging. The design of parking lots needs more attention in order to have efficient and safe design. The capacity of a parking lot depends on many factors such as the parking angle. Choosing the most efficient parking angle is not an easy task since it varies wi...
