The index system of the traffic environment evaluation of the old residential communities in the city is proposed, including pedestrian crossing index, no sidewalks stretch length ratio, the ratio of parking berth supply and demand, the proportion of illegal parking in the road, the average walking distance for parking, the ratio of the number of parking spaces and the number of households, the per capita walking space, the percentage of barrier-free passage, the percentage of blind passage, the ratio of supply and demand of non-motorized berths, the ratio of the number of vehicles parked on the ground and the area of the community, the ratio of external through traffic turnover and the area of the community and so on. The calculation methods and obtaining methods of the specific indicators are given. Taking the four typical old residential communities in Changsha as an example, the appraisal method is demonstrated and general problems exist in the old residential communities in the city, including mixed people and vehicles, serious interweaving of people and vehicles, shortage of parking berths, and uncontrolled parking of vehicles.
