Police reported 96 cases of men cruising for prostitutes, most in the city's traditional red light areas, in 2012-13.
That is up from 86 in 2011-12 and double the 48 recorded in 2010-11.
The figures do not include the scores of men - who are not always motorists - who have been warned after being spotted behaving suspiciously in the Broomielaw and Glasgow Green, the city's two main problem spots for outdoor prostitution.
Those convicted last year for kerbcrawling in Glasgow include South Lanarkshire councillor Bill Holman, 65. He said he was in the Broomielaw late one evening before Christmas trying to get a signal to phone his wife. He was later fined £250.
Kerb crawling - or soliciting the services of a prostitute - became illegal five years ago.
Detective Superintendent Peter McPike, of Greater Glasgow Division, said: "We will rigorously enforce the kerb crawling legislation. Offenders will be caught and reported to the Procurator Fiscal, if not at the time, through our retrospective investigation."
Officers policing the main areas believe even the prospect of a modest fine and conviction for kerb crawling terrifies most punters, many of whom are married and could lose their partners if the crime becomes known.
Police - working with their colleagues at Glasgow Community and Safety Services, a joint venture between the force and the city council - usually see women working the streets as victims and their punters as offenders.
However, they continue to report prostitution offences by women and men selling sex, some 214 in 2012-13. It was 211 a year before.
This figure includes prostitutes found breaking the law outdoors and in flats or brothels - indoor premises with more than one sex worker.
There were 12 cases of brothel-keeping in the city last year, down from 14 the year before but still double the six for 2010-11.
Kerb crawling in Glasgow is heavily focused in just a few police beats.
Forty-three of the 96 cases were in Alpha Charlie 21, the western end of the Broomielaw and adjoining streets.
Traditionally, the other main pick-up point for prostitutes has been near Glasgow Green, and there were 11 kerb crawling offences detected last year in Calton Barras, the nearby beat.
This beat also saw 41 cases of prostitution offences by those selling sex.
The second busiest beat for kerb crawling was Collegelands, on the eastern edge of the city centre. It had 12 cases in the year, up from two in 2011-12.
The area also had a increasing number of cases of prostitution recorded, 38, according to the most recent figures.
