Contrary to populist belief, double glazing is not the best way to reduce noise - full stop.
It is just one expensive way to reduce some noise.
If traditional single glazed sash windows are the only barrier between you and the traffic you can tackle a major part of the problem by simply installing draught proofing.
As well as draughts, draught proofing also reduces airborne noises which find their way through the smallest and least noticeable gaps.
The next step is to replace the glass in the sashes.
There are many types of acoustic glass, available in various thicknesses, and designed to control various levels and types of noise.
Developed and tested by the larger glass manufacturers (e.g. Pilkington Glass) the results are often not as impressive in real life situations as they may be on paper.
Sound insulation is probably best achieved via well fitted windows with good draught strips, laminated safety glass 4.4mm or 6.4 mm thick may not be quite as acoustically efficient as the best specialist glass but, at a fraction of the price, it will dramatically assist in overall noise reduction.
