Deploying Lanes for High Occupancy Vehicles in Urban Areas

Simulations and field experiments in previous works suggest that a freeway’s general purpose lanes (those not dedicated to high occupancy vehicles) discharge vehicles from bottlenecks at an equal or higher average rate when one of the lanes is devoted to high occupancy vehicles than when it is not. This result was used in these previous works to develop formulae for the total discharge rate of ...

Optimal Dynamic Pricing Strategies for High- Occupancy/Toll Lanes

This paper proposes a self-learning approach to determine optimal pricing strategies for high-occupancy/toll lane operations. The approach learns recursively motorists’ willingness to pay by mining the loop detector data, and then specifies toll rates to maximize the freeway’s throughput while ensuring a superior travel service to the users of the toll lanes. In determination of the tolls, a mu...

The gifts reserved for age.

Many disciplines from the biological and social sciences are relevant to the study of human ageing. The unique contribution of epidemiology lies in defining the phenomenon of ageing and identifying the influences that determine its manifestations. With sadness we recognise, wherever we look in the world, that these influences include privilege, prejudice, and politics. Ageing, in the sense of s...

The Feasibility of Reducing Energy Consumption by Allowing High-efficiency Vehicles to Operate on High-occupancy Vehicle (hov) Lanes

Design of a High Range, High Efficiency Spread Spectrum Transmitter for Audio Communication Applications

This work proposes a direct sequence spread spectrum transmitter with high transmission range and efficiency for audio signals. It is shown that by choosing high process gain for spread spectrum signal the data could reach a range of 55km in the 2.4GHz ISM band. By employing a light modulation scheme, we have a relaxed SNR requirement for having a low bit error rate (BER) which translates to re...
