The addition of control systems to highway vehicles has received considerable attention in recent years. Much of this work pertains to the development of control systems for passenger cars. However, since the power-to-weight ratios of heavy trucks make them quite different from passenger cars with regard to maintaining speed and headway, tieaVy·tnickS merit special attention. This paper focuses...

Diffusion of alternative powertrain concepts in heavy commercial vehicles will start in the upcoming years after electrification and natural gas engines have already been introduced for passenger cars. Numerous quantitative forecasting and technology diffusion models exist for passenger cars but cannot be transferred unchanged to heavy commercial vehicles. A system dynamics model for the diffus...

conclusions the seatbelt wearing rate among the study participants was much lower than the 90% rate reported among iranian drivers in 2010. mandating seatbelt use, as in most countries, will be more effective if a combination of factors such as changes in vehicle design, road safety, and driver and passenger behavior are taken into account. background seatbelts are a relatively low-cost safety ...

Changes in the U.S. domestic airline route system have increased competition between international gateways. To assist in understanding this phenomenon, a system of models that predicts airline passenger flows resulting from different airline gateway hubbing strategies has been developed. The calibrated rnodels predict baseline passenger Mows quite accurately. The system was then used to projec...
