City of Tokyo Metropolitan Highway Line

The city needed a low maintenance, highly reliable communications system that was sufficiently robust for the delivery of constant updates to the kiosks. One of the problems facing the developers was that the environment in which these connections are maintained runs the gamut: under roadways and rail lines, next to hot cabling in the transit system through a variety of soil and wetness conditions. Depending on weather conditions, the transmission capabilities of the various physical media can vary widely.

  • RTI
    RTI provides the connectivity platform for the Industrial Internet of Things (IIoT). RTI's solutions connect across field, fog and cloud. Its reliability, security, perfomance and scalability are proven in the most demanding industrial systems. Deployed systems include medical devices and imaging; wind, hydro and solar power; autonomous planes, trains and cars; traffic control; Oil and Gas; robotics, ships and defense. RTI is the largest vendor of products based on the Object Management Group (OMG) Data Distribution Service™ (DDS) connectivity framework.
  • Construction & Buildings
  • Logistics & Warehousing
  • The City of Tokyo Metropolitan Highway Line system consists of a central information-control center and hundreds of information kiosks and displays scattered along the highway. This allows the drivers and passengers who visit the rest stops to get information on traffic conditions, projected arrival times, alternate routes, and enforcement points where traffic is being redirected or controlled due to obstructions in the roadways caused by construction or accident.

  • With RTI middleware, system designers do not need to be concerned with the underlying communications protocols. The developer only needs to tell the system what the bandwidth constraints are, what information is needed at each node, what actions need to be taken, when to send it or to receive it, and what is required in response.

  • Arrival Time, Communication Performance, Infrastructure Condition, Routes, Weather
  • Emerging (technology has been on the market for > 2 years)
  • Impact #1
    [Efficiency Improvement - Communication]
    Designers can adapt RTI publishsubscribe middleware to a heterogeneous system with servers and terminals based on different types of processors and running different operating systems.
    Impact #2
    [Efficiency Improvement - Production Uptime]
    The performance of typical network protocols is dependent on the bandwidth available. Publishsubscribe is much more forgiving and able to work with a minimum bandwidth.
    Impact #3
  • Smart City Operations
    Smart city operations include the range of solutions required to enable smart city concepts by integrating information and communication technology with senors and connected devices to optimize the efficiency of city operations and services. Smart city technology allows city officials to interact with both community members and city infrastructure and to monitor situation in the city in real time. Benefits for city managers include tracking events in the city in real time, managing congestion, improving operational efficiency, reducing emergency response times, and enabling remote management. Modern solutions will aim to integrate all city data into a single dashboard. Both historical and current KPIs are measured to conduct performance reviews and gap analysis, and to plan future infrastucture and service investments.
