Potential for growth of public transit is limited as most tourists come by car or tour buses.
Niagara Falls Transit is very underused due to the poor route structure, infrequent route intervals.
Half hour or 15 minute routes are non existent even at rush hour.
There is also a lack of pedestrian friendly bus stops, no concrete padding at many stops with few bus shelters to accommodate riders.
Hotels and the two casinos offer shuttle bus service around the Falls area.
Taxis are also a common form of transportation in the city.
Most commuters are locals who live away from the Falls area and need to get to their workplace.
5-0 is also a carrier that provides service from the Fallsview Casino and Downtown Niagara Falls area to Niagara-on-the-Lake, using a motor coach.
Service operates year-round, but with a dramatically reduced schedule during winter months.
Niagara Falls Transit offers four shuttle bus routes, the Brock Rapid, Niagara College/Glendale Campus, Niagara College/Welland Campus, and Fort Erie to Niagara Falls.
The Brock Rapid, Niagara College and Fort Erie shuttles operate during the academic school year.
These services carry a premium fare charge, but in many cases will allow you to connect to regular services offered by Niagara Falls Transit.

Other daredevils have made crossing the gorge their goal, starting with the successful passage by Jean François "Blondin" Gravelet, who crossed Niagara Gorge in 1859.
Between 1859 and 1896 there was a wire-walking craze, and there were frequent feats over the river below the falls.
One inexperienced walker was able to slide down his safety rope.
Only one man fell to his death, at night and under mysterious circumstances, at the anchoring place for his wire.
These tightrope walkers drew huge crowds to witness their exploits.
Their wires ran across the gorge, near the current Rainbow Bridge, not over the waterfall itself.
Among the many was Ontario's William Hunt, who billed himself as "The Great Farini" and competed with Blondin in performing outrageous stunts over the gorge.
On three separate occasions Blondin carried his manager, Harry Colcord, on his back—on the final time being watched by the Prince of Wales.
In 1876 23-year-old Italian Maria Spelterini was the only woman ever to cross the Niagara Gorge on a tightrope, making four separate crossings over a period of 18 days.
On July 12 she crossed wearing peach baskets strapped to her feet, on July 19 blind-folded, on July 22 with her ankles and wrists manacled and finally on July 26.
Never performing again at Niagara, her personal life remains a mystery and the date and place of her death are unknown.
Tightrope crossings of the falls ended—by law—in 1896, when James Hardy crossed.
On June 15, 2012, high wire artist Nik Wallenda became the first person to walk across the falls in 116 years, after receiving special permission from both governments.
The full length of his tightrope was .
Wallenda crossed near the brink of the Horseshoe Falls, unlike previous walkers who had crossed farther downstream.
According to Wallenda, it was the longest unsupported tightrope walk in history.
He carried his passport on the trip and was required to present it upon arrival on the Canadian side of the falls.
