Safety Studies

The Segway® Personal Transporter ("Segway PT") has been evaluated by four independent agencies representing interests from around the world.

This white paper was written by Jerry Kerr, President, Disability Rights Advocates for Technology, to outline the benefits of the Segway PT to users who need assistance walking, but are still able to safely operate a Segway PT. The paper also supports the finding that use of a Segway PT adds to the users quality of life. The paper also compares safety statistics among Segway PTs, scooters, manual wheelchairs and power wheelchairs. It reports that adverse incidents on Segway PTs are infrequent and relatively minor in nature.

The Second Phase of the two-phase report detailed use of the Segway PT by 143 participants who rode more than 9,000 total kilometers on sidewalks, paths, and roadway shoulders, in three major cities located in the Province of Quebec. The report noted that no incident or serious injury, nor any Segway PT/pedestrian collision or physical interference, was reported during the evaluation. Upon completion the study "Recommendations" indicate that Segway PTs should be allowed to operate on urban pedestrian areas and that such use will have little impact on user safety and still less on the safety of pedestrians, cyclists, motorists and other walkway users.

The first phase of the two-phase report detailed information discovered during the evaluation of motorized personal transportation devices (MPTD) specifically, the ergonomic, operational and technical aspects of the devices. Findings included that the Segway PT was very stable and gave users a feeling of being in control. Also, Segway PTs compared favorably to other types of devices and were far superior in the area of stability as compared to bicycles and mopeds. Lastly the report noted that the Segway PT could meet a large number of mobility requirements for a broad market, could facilitate transfers to other forms of transportation, and serve as an alternative to automobiles.

The three-month study was conducted by the German government in conjunction with the Ministry of Internal Affairs, Ministry of Commerce of the Saarland, Saarbruken Police Department, and Municipal Office of Neunkirchen. Results for braking, steering and general handling of the device were very favorable. The study also reports that Segway PTs are best suited for bicycle lanes and pedestrian traffic areas.

This study researched the use of various personal mobility devices such as electric scooters, powered wheelchairs and Segway PTs on non-motorized infrastructure including sidewalks and bike lanes/paths. Overall the study found that Segway PTs would have medium impact or risk to others (namely pedestrians), the same which was found true of joggers and runners. As a comparison, bicycles were found to have medium to large impact or risk to others.

The study was undertaken to clarify the operational characteristics of both motorized and non-motorized transportation. Data was collected to obtain physical dimensions, turning capabilities, acceleration, speed and stopping distance of these devices. The Segway PT and its rider were found to have the second shortest braking distance, highest sight lines, one of the smallest footprints, and quickest perception-reaction time. The Segway PT met or exceeded all recommendations made by the American Association of State Highway & Transportation Officials (AASHTO) Guide to the Development of Bicycle Facilities.
