Optimize the waiting time locally 优化本地等待时间 Intelligent intersection 智能路口 – Citilog Technology 2 ARTIC : Advanced Real Time Intersection Control 先进实时路口控制 Adaptive Micro regulation 自适应微观调节 Based on queue length, and safety constraints 基于排队长度，和安全限制 BUS Optimize the waiting time locally 优化本地等待时间 Tested solution: 30% gain on average waiting time, 4% to 12% pollution reduction. 经过验证：减少30%等待时长，减少4%-12% 的污染排放

Potential benefits ARTIC -Tested solution (IEE RTIC 2000): INRETS: National Research institute for Transport and Safety 法国国家交通与安全研究中心 Congestion benefit 减轻拥堵: - 20% gain on average waiting time 减少了20%的平均等待时间 - 11% less stop 11%车辆停止状态 Pollution and CO2 reduction 污染与二氧化碳排放降低:   CO HC Nox CO2 Fuel Benefits versus actuated operation 4,0% 5,0% 3,0%

Potential benefits when applied on large scale 当大范围应用后所产生的潜在效益 In IEE RTIC 2000 study, with an average of 2100 Veh/h, the cost of actuated operation for one intersection, was: 经过研究，在一个平均车流为2100辆/小时的路口，污染消耗为：   CO(g) HC(g) Nox(g) CO2(g) Fuel(g) g per vehicle 1,85 0,14 0,165 40 27 Under the same conditions, applied of 600 intersections, ARTIC will allow the following saving per year: 相同条件下，当ARTIC应用在600个路口时，将会在一年内减少     CO(kg) HC(kg) Nox(kg) CO2(kg) Fuel(kg) Kg per year 600 intersections 816 782 77 263 54 636 17 660 160 11 920 608

Example: Bus Rapid Transit Lanes 示例：公交快行车道 Integration with High level of service transportation systems 与高等级交通服务系统整合 Example: Bus Rapid Transit Lanes 示例：公交快行车道 Bus Rapid Transit (BRT) Lanes is a recognized cost effective Mass Rapid Transit solution for medium to large cities. 公交快速车道被认为是针对中大型城市集群快速运输的一种高性价比方案 The example of Kunming 昆明为例: After the implementation of the BRT system: BRT系统投入使用后： Bus capacity increased by 46% 公交车运力提升了46% Car traffic volume on the same route decreased by 20%. 小型车辆在相同路径中使用比例降低了20%。

BRT Benefits效益 / Risks风险 Maximize dedicated road capacity for public service 将道路最大承载能力提供给公共交通: Reduce average trip time 减少了平均出行时间 Increase bus capacity 提高了公交车运力 Increase bus lane efficiency 提高了公交车道的效率 BRT Increase congestion on bus routes for others users. 加重了公交沿线道路其他车辆使用者的拥堵 Increase congestion on alternative routes due to a transfer of traffic. 加重了沿线其他替代路线上的交通拥堵。

Video analytics视频分析 & ARTIC + BRT Integration of ARTIC and BRT 将ARTIC与BRT整合: The BRT lane will reduce the road capacity for other road user by 30%. BRT车道将会使其他道路使用者的通行能力降低30% Previous implementations show that the car traffic on the bus routes will decrease by 20 to 25% (alternative routes and usage of bus service). 过去的应用案例显示，在公交沿线相关路段，小型车辆的通过量将会降低20%到25% (选取替代路径和使用公共交通) On a first approach the ARTIC system on the bus route will compensate for the road capacity decrease and the level of congestion on the bus routes will remain constant if not less. ARTIC系统能够对公交沿线道路通行能力进行补偿，使得沿线交通拥堵程度保持稳定。 Implementation of ARTIC on alternative routes 在可选择路径上应用: Because of the traffic transfer from the BRT routes to alternative routes, congestion level will increase on alternative routes. 由于本应在BRT路段的交通流分流到其他可选路径，其他道路拥堵程度会增加。 On these alternative routes ARTIC will more than compensate the potential increase in congestion level. 在这些替换道路中，ARTIC 可以更好地控制潜在的拥堵等级。

Video analytics视频分析 & ARTIC + BRT Maximize dedicated road capacity for public service:提升道路通行能力为公共交通发挥最大功效 Reduce average trip time 减少平均出行时间 Increase bus capacity 增加公交车运力 Increase bus lane efficiency 提高公交车道使用效率 Maintain level of Congestion on the bus routes. 保障公交线路拥堵级别可控。 Optimize the level of congestion on all other routes. 为所有周边路线优化交通流量。 ARTIC + BRT General benefit 普遍效益: Globally the combination of ARTIC and BRT will achieve a sustainable balance between: 广泛地将ARTIC与BRT相结合，能够达成一个可持续的平衡： the benefit of the BRT for the bus users, 公共交通使用者权益 the benefit of the Congestion management for the private vehicle users, 通过拥堵管理，保障了私家车用户的权益 a general positive impact on air pollution and Fuel consumption. 对空气污染和燃油消耗的降低起到了正面积极作用。
