In this paper we analyze in detail the energy consumption characteristics of the Wireless HART protocol when operated with a popular transceiver, the ChipCon CC2420. We analyze how much various factors contribute to the overall energy consumption over a longer period of 12 h. These factors include the amount of management traffic and the power levels required for various transceiver activities ...

The use of reclaimed asphalt pavement (RA) in new asphalt pavements can provide important economical savings, while reducing the negative environmental impact. The European research project PARAMIX aims to improve the techniques for hot mix recycling in plant and cold mix in situ recycling, so as to increase the amount of reclaimed asphalt and develop competitive road pavement rehabilitation te...

As a result of the increasing use artificial intelligence technology in transportation, numerous real-time crash prediction techniques have been developed. In context highway traffic management, machine learning models and classifiers are used to analyze electronic toll collection (ETC) vehicle detector (VD) data predict occurrences. However, accidents influenced by multiple factors, such as sp...

Automatic Vehicle Identification (AVI) has many applications in traffic systems (highway electronic toll collection, red light violation enforcement, border and customs checkpoints, etc.). License Plate Recognition is an effective form of AVI systems. In this study, a smart and simple algorithm is presented for vehicle’s license plate recognition system. The proposed algorithm consists of three...

By introducing the speed-elasticity of flow, this paper provides a generic characterization for equilibrium speed-flow curves that satisfy the fundamental identity of the traffic flow. With this new characterization, we have integrated several well-known speed-flow models, including the classic Greenshield-type and Underwood-type models, and the most recent specifications for highways from High...

Coordination is an essential ingredient of joint activity in humanagent-robot teams. In this paper, we discuss some of the challenges and requirements for successful coordination, and briefly how we have used KAoS HART services framework to support coordination in a multi-team humanrobot field exercise.

This research considers congestion pricing under demand uncertainty. In particular, a robust optimization (RO) approach is applied to optimal congestion pricing problems under user equilibrium. A mathematical model is developed and an analysis performed to consider robust, dynamic user equilibrium, optimal tolls based on the second-best problem known as the dynamic optimal toll problem with equ...

Residents of Minnesota often joke that the state has two seasons, winter and road construction. The joke has more than a grain of truth: Harsh winters take a high toll on our state’s highways, and the warm months are consequently filled with an intense burst of road construction and repair. This second season also exacts a high toll, and the price is paid by Minnesota motorists who suffer painf...
