State-of-the-art in dynamic management of road lanes
• Increasing the number of lanes
• Segmenting traffic according to categories
• The creation of specialized lanes
• Sufficient space
• Dynamic allocation of lanes to different types of transportation

Dynamic circulation lane allocation
System designed to share circulation
lanes dynamically between public
and personal vehicle

Global view of the dynamic lane allocation environment

15. 15
This system vision involves the main elements :

16. 16
Internet of Things
• Human participation in these activities must be limited to essential
situations
• In this way, communication must be established between things
• From a technological point of view, to integrate ‘‘anything’’ into the
Internet, identification, sensing and communication technologies are
key elements

17. 17
Internet of Things
• One of the most widely used is RFID systems consisting of readers and tags
• cheap cost
• low energy consumption
• Wireless sensor networks are able to cooperate with RFID systems to better track the
status of objects, i.e., their location, temperature, movements
• Besides ordinary objects, devices in which a certain degree of intelligence is embedded
also need to be included in the network
• Zigbee
• Bluetooth
• low-power WIFI
• 6LoWPAN
Wireless sensor networksRFID tag RFID reader

18. 18
Location-Based Services
• Communication between a bus and a detection sensor on the road must be conducted at an appropriate
distance
• in order to allow system reaction according to the actual fluidity of the traffic
• Location-Based approach is the answer
• Location-Based Services (LBS) provide mobile users with personalized services according to their locations
• Use GPS and other location sensing technologies

Mock-up technology validation
An overview of the mock-up:
• 3 lanes are painted on the cardboard
• The reserved section will be found on the right lane
• Display panel is placed over the cardboard as horizontal signaling
• Detection of the vehicle with priority takes place both at the
beginning and at the end of the section
• To collect the information ‘‘Priority vehicle detected!’’ and actuate
the signaling, we use Arduino cards

23. 23
Arduino cards
• These cards contain a set of analog/digital input/output pins and several types of data bus
(SPI, I2C and RS232), controlled by a microcontroller
• With the addition of an Ethernet cable, the data processed by the microcontroller can be
transmitted via a TCP/IP network
• The card plays the same role as the regulator in our system
• Implement a server to centralize management of Arduino cards

24. Mock-up technology validation
• With respect to signaling, for simplicity’s sake, we use red LEDs for ‘‘closed to other
vehicles’’ and green LEDs for ‘‘open to all’’
• To integrate the LED into the TCP/IP network or Web
• Connect the LEDs to the digital outputs of an Arduino card
• Use the RESTarchitecture with two sets of resources, ‘‘analogs’’ and
‘‘digitals’’, including the pin numbers

25. 25
REST
• REST is an architecture style for designing networked applications
• The idea is that, rather than using complex mechanisms such as CORBA, RPC or SOAP to
connect between machines, simple HTTP is used to make calls between machines
• Client-server
• Stateless
• Cacheable
• Layered system
• Uniform interface
• Code on demand (Optional)

With Web Services and SOAPWith REST
RESTful

26. 26
Mock-up technology validation
• We can expect an output of a LED status by using the HTTP GET method with the URI
http://ipArdress/digitals/2 if the LED is connected to the digital pin 2 of the Arduino
card
• To modify the status of the LED : HTTP POST method and a value (0 or 1) as
parameter
• The resource representations are available in the JSON format
• To vehicle detection : use RFID

27. 27
Mock-up technology validation
• Once a vehicle is detected, the information must be sent without a request, we cannot
use the traditional HTTP query/response model
• HTTP request is sent to the central server when a tag is detected
• Server interprets the request and uses a WebSocket to send to potential clients
• WebSockets is an advanced technology that makes it possible to open an interactive
communication session between the user's browser and a server
