From January to October, 518 people died in the city, with 56 resulting from accidents along Mombasa Road.
The NTSA cited Mombasa road, Thika Superhighway and Waiyaki way as the most risky; it recorded 44 and 39 respectively fatalities on the latter two roads respectively.
On North Airport Road this year, 11 people have died compared to 18 in 2014.
The authority reported that the highest number of deaths are recorded on Saturdays, followed by Sundays.
In 2013, 3,218 people died in road accidents compared to 2,907 in 2014, representing a 9.66 per cent decline.
Speaking during a safety campaign on North Airport Road on Thursday, Traffic commandant Jacinta Kinyua said police will continue to work with the NTSA to reduce road carnage.
Kinyua commissioned a pedestrian foot bridge, which she urged residents to use, and motorists against violating traffic regulations and driving after drinking.
Several drivers and pedestrians disobeying traffic rules were rounded up; Kinyua pardoned some who were found speeding.
Dominic Kabiru, NTSA deputy communications director, said road safety campaigns will be rolled out to other parts of the country.
