In the New Era, counties, which account for two-thirds of China's land area, have become one of the mainstays of emission reduction and green development. And the low-carbon-oriented urban transport facilities allocation counts for reducing carbon emission. To adjust the allocation of on-street parking facilities with the goal of reducing carbon emissions is conducive to boosting the efficiency of dynamic traffic and promoting the establishment of green travel structure, and which is helpful to the improvement of human settlements in small towns. This paper identifies four typical types of on-road parking in County towns, namely parallel parking set on bicycle lane with isolation, parallel parking set on the roadside without isolation, right-angle parking set on pavement need to drive back-in and forward-out, and right-angle parking set on curb need to drive forward-in and back-out. By investigating and analyzing the on-street parking process under actual traffic conditions, the characteristics of parking and departure process are obtained, including the duration of both processes, the times and duration of vehicles stopped due to the disturbance caused by vehicles in the traffic stream. At the same time, parameters such as V/C are obtained. Based on these parameters, a carbon emission measurement experiment for on-street parking was designed. A Volkswagen LaVida, which is common in small towns, was selected to simulate the actual parking and departure process by skillful drivers at the experimental site. Vehicle exhaust gas analyzer SEMTECH-DS was used to obtain speed and emission data of the vehicle. By the analysis of the data, the carbon emission levels of four typical types of on-street parking are obtained, and the optimization method of on-street parking facilities allocation in small towns aiming at reducing carbon emission has been provided, that is, the typical on-street parking which should be selected to be coped with various V/C.
