Traffic Management Solutions


I am Ray Pearson, candidate for City Council in the 3rd District.


To improve traffic management in the city, I propose to implement the following four goals:

  1. Ensure free flow of traffic: Traffic flowing freely within a network is like the blood flowing in human system. A blockage paralyses activities within the system just as any impediment in the flow of blood within a human system paralyses the body. Ensuring traffic flow is therefore a goal central to any traffic management strategy.  Traffic flow is a function of many factors.  They include road type/function, abutting land uses, and the characteristics of the traffic volume. The dynamics of traffic must be understood determined by daily, weekly and yearly variations. Likewise, the direction of flow at any particular point is vital. It shows the point of traffic attraction and generation. A good traffic volume study will assist in the management of the traffic flow to a point of according priority to the stream with higher volume.

  2. Reduce congestion and delay: Traffic congestion results when so many vehicles are trying to maneuver within limited road space. Such places on the road are referred to as “chock points” or bottleneck. It could be on a stretch of road or at an intersection. In most cases other than intersection, “chock points” are caused either by on-street parking, bad road, street trading, broken-down vehicle and/or abandoned crashed vehicle.  In any high traffic volume road, a minute delay in traffic creates the piling up of vehicles. An effective traffic management strategy must reduce delay on any part of the road network.

  3. Increase road capacity: Every road has design capacity. This, in the main, is about “Average Daily Traffic (ADT)”.  A road may not be able to carry the volume of traffic for which it was designed where appropriate traffic management measures are not installed, especially at traffic nodes.  Every road junction and intersection has designated capacity.  This capacity can be increased when appropriate traffic management measures are installed such as road markings, traffic light and signs, which of course will allow the facility to handle more traffic within a reasonable time frame.  There are arguments however that some traffic management installations reduce road capacity e.g., speed control devices.

  4. Reduce road traffic crashes (accidents): Road crashes have become a major concern in Carlsbad. Every goal of traffic management is set to achieve safety of lives and property. Efficient and effectiveness of road transport system is tied to safety.  From designing of roads to construction of vehicle, and training of operators, safety is the first consideration. Whatever policy or physical measure a traffic manager is trying to adopt therefore, safety of road users is the paramount consideration. It, therefore, means that traffic management's primary aim is to reduce loss of lives and property on highways. Appropriate traffic management measure must be put in place to ensure that such facility adequately handles the traffic to avoid a chaotic situation or delay. Removal of traffic obstruction is another area of traffic management. It involves clearing of debris after crashes and for removal of broken-down vehicles in record time. When traffic congestion is properly managed, traffic will flow steadily, delay will be reduced, and more vehicles will use the road facility.  More importantly, when traffic is managed with appropriate measures, especially at traffic nodes, conflicts are eliminated. Every vehicle will have a safe passage. Safety of road users is an important goal of traffic management.


Smart Corridors

Sections of roads will feature technologies which can alert drivers of the upcoming traffic conditions, including any accidents that lie ahead, how long it will take them to reach a particular destination, impending weather events, and other obstacles that could impact driving. Smart corridors can keep motorists “in the know” so that they can plan ahead, which in turn can help to ease traffic. These are just some examples of how cities can and are tackling congested roadways with technology.


Cities Turning to Internet-of-Things to Help Solve Traffic Congestion

Traffic congestion has become such a pressing issue for city officials that cities around the world are spending $41 trillion on smart city technology by 2022.  The Smart City Council says that an intelligent city uses the information to make their cities more livable, sustainable, and enjoyable compared to traditional towns. While smart cities are the future of urban landscapes, every piece of technology in a network needs to work together flawlessly so that community leaders can implement strategies to accomplish their goals. Cities will be able to implement various systems to address traffic congestion like Vehicle-to-vehicle (V2V) communication and Vehicle-To-Infrastructure (V2I) communication. While both of these terms sound similar, in reality, they are much different since V2V has to deal with communication between individual vehicles, and V2I communicates with vehicles from infrastructures like traffic cones and traffic signals.
