An oneway value of -1 means that the way is oneway, with allowed passage opposite to its way direction.
Where possible, consider reversing the way and replacing with oneway=yes. This isn't always an option, though, e.g. when using Conditional restrictions to map oneway rules which depend on the time of day.
