40、交通拥挤并对拥挤问题进行分析，试图找到一个相应的合理的方法解决交通拥堵问题。关键词:交通拥挤;系统的产权制度；管理需求; 政策。 交通拥挤现象是由于交通供给与需求不均衡所造成。城市交通拥挤的影响体现在很多方面: 它降低了居民的旅行速度，导致高的出行费用，严重的环境污染和频繁的交通事故，从而降低整个城市的节奏，甚至影响相关行业的发展如汽车和旅游业。因此我们必须找出交通拥堵的经济方面的起因，并尽可能找到一个相应的合理的方法来解决交通拥堵问题。从经济学角度解释和分析道路的交通拥挤从经济学角度解释道路的交通拥挤 以城市交通拥挤为例，市民乘公交上班平均每天花费十分钟，如果他们开车，可以缩短为5分钟。如果
41、没有人开车，那些乘公交车的人将不会受到影响。但是如果在交通高峰期有太多的轿车,这将造成交通拥挤,这样他们开车去工作场所的时间不仅会被缩短反而被延长，会比乘公交车上班花的时间还要多, 要15分钟,而乘公交车上班的时间将要25分钟。 从这个简单的例子， 我们能够分析造成交通拥挤的先决条件和原因 ，最根本的原因在于道路产权的管理.只要道路产权属于政府,这条道路德产权就会划分不清楚。模糊的产权制度是交通拥挤的基本原因。当道路的产权不能确定它就属于绝对的公共财产,所以对公共资源进行收费会变的很困难，最大的问题是, 他们正在使用的道路时没有考虑到成本，而且他们使用道路不需要承担任何责任。此外,他们不需要考
42、虑道路的长期使用问题,如资金回收、维修和再生产。每个汽车拥有者对道路成本的看法，是道路的产权管理所造成动机和行为的直接的体现。交通拥挤经济分析 对司机来说,他们没有看到开车外出全部成本,而且忽略了这样一个事实,即因他们加入车流,从而使其他的驾驶者行车速度降低。他们只考虑私人边际成本,从不考虑由于增加的道路拥挤程度而对其他驾驶者所带来的额外费用。只要个人驾驶利润比个人边际效益高，就不断加入驾车行列.对每个人来说，个人实际花费低于和他们一起开车对他们产生的实际费用。也就是说,这是边际社会成本(MSC),因此为拥挤成本等于MSC减去MPC。 城市交通需求的特点使道路资源在非高峰期不能充分利用和在交通
43、高峰期过于拥挤。事实上，在交通高峰期交通量取决于交通需求曲线，并且边际私人成本使城市交通不可能达到最佳的经济效益。 简单分析交通拥挤后，我们可以着手探讨对产权的分配。如上所述，道路过度使用的原因是道路的产权的管理。道路的产权的管理会不可避免的带来道路使用者的不合作，这在区别边际社会成本和边际个人成本之间的差异中已经体现出来。因此解决目前交通拥挤问题就是要克服的私人成本之间和社会成本的差异，并系统的改变道路产权的管理。明确道路产权是解决交通拥挤的先决条件。当道路的产权属于政府，而政府又不向使用者收费，这样有限的道路资源免费的提供使用，道路一定会拥挤甚至堵塞。交通拥挤问题解决办法 根据以上分析,
44、为解决道路拥挤这一问题，我们必须从道路使用者收取额外通过费用, 在此边际私人成本基础上的承担另一部分费用，数额应相当于边际社会成本和边际私人成本的差值,也就是拥挤的影响，通常被称为拥挤附加费。过路费 许多经济学家倡导要通过征收过路费来解决交通拥挤的问题，所谓道路使用费政策是指通过政府收取的过路费,相当于C1-C2的差值。这样使边际个人费用水平提高到边际社会费用，从而降低车流量。 通过征收道路使用费用解决交通拥挤问题会面临一些政策局限性问题，首先道路使用费要在一个私家车占有分大份额的交通运输市场结构中实施。通过交通需求方式的转移或替代,即通过增加驾驶费用的一部分,使私人车主放弃私人交通而改为公共
45、交通。在发展中国家，例如中国，私家车的比例较低,所以仅仅通过对私人车主收集道路使用费的方式来解决交通拥是非常有限的。此外,还将受到公众的争议和反对。在中国,征收道路使用费应当以企业和公共机构为主，通过提高费用，在这些单位私人用车的经济优势就受到限制。这样就会使他们通过公共交通或专业运输企业解决交通问题。 道路使用费是通过定价杠杆来解决交通拥挤问题。这可能会把较低的收入的人排除到道路使用之外,使开车成为富人的一种特权的.一个问题涉及到社会公平的问题会出现.当交通需求的灵活性较低,交通穷光蛋就会产生.很明显，如何利用道路使用费用是一个非常重要的问题，理想的效果是给交通穷光蛋一定的补贴, 来弥补他们
46、被从马路上赶跑的损失，同时不让他们回到道路开车。因此经济学家建议政府应该用这一部分税来提高公众交通系统,从而使较低的收入的人能够利用政府提供的公众交通系统,同时较高收入的人通过支付一定的费用保持道路的使用权利。 提高道路使用费用,使 MPC提高以至确定合理的车流量。不仅在某种程度上能解决道路的过载这一问题,延长道路的使用寿命,使交通量出于最佳水平,还让车主支付合理费用,包括合理的道路使用费。这样减少了城市的经济负担,实现经济双赢。同时驾驶流量的减少也会减少环境污染(如噪声、废气)这样的效应。征收交通拥挤税 交通拥挤常出现在有大量的交通需求一段的时期内。为了解决在特定时间内出现的交通拥挤问题，一
47、些经济学家建议采取征收交通拥挤税的方法,其核心是解决交通需求时间上的矛盾,通过调整交通高峰和空闲期的费用,从而引导旅行者常在较空闲的时候使用交通工具。 通过征收车辆运行在交通高峰期的交通拥挤税,有些车辆会选择在交通空闲期出行。用这种方式，在某种程度上交通的高峰期的交通紧张将会减少, 与此同时, 在交通空闲期就会满足需求,从而带来最多的经济效益。交通高峰期征收交通拥挤税,使相应的运输净增加量将减小,交通需求曲线会向左移动，如果总交通需求不会发生改变,交通需求在空闲期将随之增加,然后高峰期空闲期之间的交通需求之间的差距也会缩小。应注意到的是,如果需求在交通的高峰期和空闲期达到均衡,这将在点E与时间
48、成本曲线有叉点，每次都控制在Q0交通量，那么最大的经济效益一定能实现。 但是,作为一种时间差别定价政策,交通拥挤税在实际中还将面对许多问题。拥挤税征收对象是交通使用者，越拥挤征税越多。而交通拥挤产生的原因是为工作乘车,所以它将引起工薪阶层的谩骂。但如果交通费用针对企业和公共机构,这种情况将从本质上被改变，在实践中这这种方法也很受欢迎。交通拥挤费可以直接从高峰期运行的车辆征收,或者对高峰期运行车辆比空闲期运行车辆收取更高的牌照费。至于前种情况，应当在车辆必须通过的关键地方建立取费站,但是显然征收费用需要一些成本，例如建收费站成本，收费员的薪水，运行车辆缴费消耗的时间，有时甚至增加拥堵程度。后一种情况，不需要相应的收费成本，但相应的交通监控技术必须到位，以辨别和检查不同的时间段车辆的牌照。实施拥挤税的前提和条件是旅行者能够对交通状况和不同旅行方式有合理的预测。为了有效地实施交通拥挤税政策, 必须建立和完善智能交通系统,交通信息广播系统必须完备，以便出行者提前选择经济的出行方式。
