西安市交通拥堵现象原因分析及解决对策
近几年来，西安市人口每年以高于4‰的比率增长，伴随汽车价格不断下调, 居民收入不断增加, 全市机动车数量呈跳跃式增长趋势，交通线路老化，市区现有各类机动车停车位仅占全市机动车保有量的6.5%. 另外一些公共建筑缺少配建停车场或停车库规划, 从而导致市内大街小巷存在占道停车现象. 人、车、路矛盾加剧. 交通已严重制约着城市经济发展.
交通拥堵的原因分析。一是道路设施的增长速度远远跟不上机动车的增长速度。二是现有道路网技术条件差, 瓶颈路段多。三是停车设施严重不足, 路外停车场停车泊位数量太少, 马路停车场数量过多, 严重影响了道路交通的畅通. 四是交叉口设计与管理有待改进。五是交通管理有待加强。六是客运交通结构不尽合理，公交优势不明显。 解决交通拥堵的对策。一是完善道路网的级配, 提高各级道路路网密度, 尽快改造瓶颈路段和瓶颈交叉口。二是对交叉口信号进行优化设计。三是加强交通组织管理研究, 提高组织管理水平。四是重视非机动车辆的运行管理。五是加强公共交通的运行组织工作, 逐步实施公交优先战略. 六是重视停车场地、停车容量的规划设计与建设。
Xi 'an traffic congestion phenomena cause analysis and countermeasures
In recent years, xi 'an the ratio of each year for more than 4 per thousand population growth, With car prices are lowered, the residents income increasing, the number of motor vehicles in the city has been jumped trend, Downtown traffic line aging, existing all kinds of motor vehicle parking space accounts for only 6.5% of the city's motor vehicle ownership. Other public buildings lack PeiJian planning parking lot or garage, parking phenomenon leading to the city streets exist presence. The sharpening contradictions between the people, vehicles and road. The traffic has severely restrict the city's economic development.
There are many reasons that cause traffic jams, mainly manifested in several aspects. One is the growth of road facilities far couldn't keep up with the growth rate of motor vehicles.Second, the existing technical conditions of road network is poor , bottleneck.Three is a serious shortage of parking facilities, road parking lot parking outside the quantity is too little, too many street parking lot, seriously affected the road traffic flow. Four is intersection design and management improvement.Five is to strengthen traffic management.Six is
passenger traffic structure is unreasonable, the bus advantage is not obvious.
To solve the problem of traffic congestion.One is the perfect road network distribution, improve the density of road network at all levels, bottleneck and bottleneck intersections as soon as possible.The second is the intersection signal optimization design.Three is to strengthen the traffic organization and management, improve the level of organization and management. fourth, attaches great importance to the non-motor vehicle operation and management of the vehicle.Five is to strengthen the operation of the public transportation organization work, gradually implement the strategy of bus priority. Six is attaches great importance to the parking lot, parking capacity planning design and construction.
