A Comparison of the Cell Phone Driver and the Drunk Driver
Strayer, David L. , Crouch, Dennis J. and Drews, Frank A., "A Comparison of the Cell Phone Driver and the Drunk Driver" (July 2004). AEI-Brookings Joint Center Working Paper No. 04-13. Abstract: We used a high-fidelity driving simulator to compare the performance of cell-phone drivers with drivers who were legally intoxicated from ethanol. When drivers were conversing on either a hand-held or hands-free cell-phone, their braking reactions were delayed and they were involved in more traffic accidents than when they were not conversing on the cell phone. By contrast, when drivers were legally intoxicated they exhibited a more aggressive driving style, following closer to the vehicle immediately in front of them and applying more force while braking. When controlling for driving conditions and time on task, cell-phone drivers exhibited greater impairment than intoxicated drivers. The results have implications for legislation addressing driver distraction caused by cell phone conversations. Go to article
Facts on voip
- Single point of calling With commercial services such as Vonage, it is possible to connect the VoIP router into the existing central phone box in the house and have VoIP at every phone already connected.
- A major development starting in 2004 has been the introduction of mass-market VoIP services over broadband Internet access services, in which subscribers make and receive calls as they would over the PSTN. Another challenge for these services is the proper handling of outgoing calls from fax machines, TiVo/ReplayTV boxes, satellite television receivers, alarm systems, conventional modems or FAXmodems, and other similar devices that depend on access to a voice-grade telephone line for some or all of their functionality.
- In order to use VoIP during a power outage, an uninterruptible power supply or a generator must be installed on the premises. It should be noted that many early adopters of VoIP are also users of other phone equipment such as PBX and cordless phone bases that also rely on power not provided by the telephone company.
