Integration with High Service Level Transportation systems
与高等级交通服务系统的整合
13
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%。
14
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。
15
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:
16
 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.
ARTIC
+ BRT
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。
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。
