in central North Carolina between Lexington and Thomasville features an inverted median, constructed so that an in-median, right-exit rest area can feature a historic bridge. I-77 in Charlotte, North Carolina, has a reverse median at its intersection over I-85 for on- and off-ramps without taking too much land from neighboring properties and without building many more bridges. I-84 used to have an inverted median through Waterbury, Connecticut, east of the 2-level "mixmaster" interchange with Route 8. This section of freeway was reconstructed in the 1970s, which eliminated the inverted median. Safety impact An August 1993 study by the US Federal Highway Administration quantified the correlation between median width and the reduction of both head-on accidents and severe injuries. The study found that medians without barriers should be constructed more than wide in order to have any effect on safety, and that safety benefits of wider medians continue to increase to a width of . A consequence of this finding is that decreasing the size of a median to from to add lanes to a highway may result in a less safe highway. Statistics regarding medians with barriers were not calculated in this study. Bus rapid transit Central reservations may also be used for reserved bus lanes, as in Istanbul's Metrobus, Los Angeles's J Line and Bogotá's TransMilenio. Center-lane running and island platforms installed in the medium reduce conflicts with stopped and parked cars as well as pedestrians near the curb, thus speeding service. Railway use In some cases, the median strip of the highway may contain a train line, usually around major urban centers. This is often done to share a right-of-way, because of the expense and difficulty of clearing a route through dense urban neighborhoods. A reserved right-of-way is contrasted with street running, in which rail cars and automobiles occupy the same lanes of traffic. Train lines that run in the median of highways include: Asia Beijing Subway Line 13 and Batong line run in the median of the G45 Daqing-Guangzhou Expressway and Jingtong Expressway, respectively. Israel Railways in the Tel Aviv metropolitan area along the Ayalon Highway. Kita-Osaka Kyuko Railway and the Osaka Metro Midōsuji Line along Japan National Route 423 (Shinmidō-suji) between Toyonaka, Osaka and Kita-ku, Osaka. Manila MRT Line 3 runs in the median of the Epifanio delos Santos Avenue (EDSA) between the latter's intersection with Taft Avenue in Pasay and a junction with North Avenue
