Currently, Taichung city uses the Hanyu Pinyin system of romanization on roadsigns.  Some signs, however, still retain older Wade-Giles and MPSII romanization.  Further complicating matters, many signs are simply misspelled.  Some counties and cities around the island use the alternative Tongyong Pinyin.  To help clarify the situation, the Compass Magazine map includes all three romanization systems for major roads. 

Below are a list of the top 50 main roads in Taichung city in Hanyu Pinyin, with a few common alternative names noted.  These are roads from the 'original Taichung City' prior to the city and county merger.  Some or many of the county and city roads that are contiguous (and there are many) may have their names rationalized to one name.
