R.E.S.C.U.M.E contains two prototype Connected Vehicle (CV) applications under the U.S. Department of Transportation (U.S. DOT) Dynamic Mobility Applications (DMA) Program. The R.E.S.C.U.M.E. project incorporates prototype development and demonstration of Response Staging (RESP-STG) and Incident Zone (INC-ZONE) applications using integrated technologies that mutually support each other and comprise an integrated R.E.S.C.U.M.E. bundle that is a key research activity within the DMA program.

The RESP-STG application provides situational awareness to and coordination among emergency responders―upon dispatch and while en-route― to establish incident scene work zones both upon initial arrival and staging of assets, and afterward, if circumstances require, additional dispatch and staging. It provides valuable input to responder and dispatcher decisions and actions. A range of data will be provided through mobile devices and other types of communication to help support emergency responder vehicle routing, staging, and secondary dispatch decision-making.

The INC-ZONE application improves protection of personnel at incident sites from the threat of oncoming vehicles, particularly where those vehicles are being operated outside of recommended speed, and lane guidance where there have been crashes, incidents, or other events impacting traffic such as stalled vehicles or vehicles pulled over for moving violations. The INC-ZONE application includes an in-vehicle messaging system that provides oncoming drivers with merging and speed guidance around an incident. The INC-ZONE application also provides in-vehicle alerts and warnings to drivers in violation of speed and lane closure restrictions, both for the protection of the drivers and incident zone personnel. Finally, the INC-ZONE application includes a warning system for on-scene workers when a vehicle approaching or in the incident zone is being operated outside of safe parameters for the conditions.

The Trajectory Converter Analysis (TCA) Software is designed to test different strategies for producing, transmitting, and storing Connected Vehicle information. The VISSIM add-on (TCA-V) runs with the VISSIM tool using real-time simulation vehicle information, Roadside Equipment (RSE) location information, cellular region information, and strategy information to produce a series of snapshots that the vehicle would produce. Vehicles can be equipped to generate and transmit Probe Data Messages (PDMs) or Basic Safety Messages (BSMs) which can be transmitted by either Dedicated Short Range Communication (DSRC) or via cellular. The TCA program version 2 Build 1 or 2.1 assumes perfect communication between vehicles and RSEs but future versions of the TCA 2 will include simulated communication disruptions. As soon as a vehicle equipped to transmit via DSRC is in range of a RSE, it will download all of its snapshot information directly without any loss of information. Similarly, if the vehicle is equipped to transmit via cellular, it will download all its snapshot information directly but those snapshots might be lost or delayed due to user-defined loss rate and latency.

DFW-FRATIS 1 topic

As part of the FRATIS DFW Prototype, the Leidos team created an optimization program to minimize the miles travelled for participating dray carriers. The program, title Vesco version 1.0 is now available for download on the OSADP.

Vesco Version 1.0 includes three components:

A Pre-Optimization processor, which consumes input files from the dray carriers dispatching software. This processor enumerates all available orders planned for the day, the geocodes for the pickup and dropoff locations, and the drivers available to carry these orders.
The Optimization code, developed by Productivity Apex, Inc., uses an ant colony optimization algorithm to develop an optimized plan, i.e., a recommended assignment of all orders to the available drivers. Since this algorithm employs the use of metaheuristic optimizations, the results for the optimized plan will vary even though the input files remain the same.
A Post-Optimization processor, which presents the optimized plan from PAI for consumption by the dray company dispatchers. The file format is a comma separated value (CSV) test file, and contains a summary of orders by driver, as well as detailed plans for each driver. It also contains estimated arrival and departure times at each destination and the mileage between each location.
Vesco Version 1.0 is intended for dray carrier users who have the appropriate input files from Trinium dispatching software, which is the software used by both prototype test participants.

Primary Functions:

T-CONNECT (aka Connection Protection) serves to improve the experience for a transit traveler by increasing the likelihood of making successful transfers, particularly when these transfers are multi-modal or multi-agency.

T-DISP (Dynamic Transit Operations) provides benefits to both the traveler and the transportation provider. For the traveler, T-DISP provides an ability to access real-time information about available travel options, including costs and predicted time, in order to best manage their commute. For an agency, T-DISP extends demand / response services to support dynamic routing and scheduling, and even add/remove vehicles from service, based on traffic conditions, vehicle capacity, ridership and origin-destination, among other factors.

D-RIDE takes the concept of traditional pre-planned ridesharing (i.e., carpooling) and brings it into the 21st century. It does this by leveraging the positioning, messaging, and computing capabilities of today’s smartphones, and advancing an application that will let drivers and travelers, in near real-time, exchange information about needs or in case of a driver, available space.

INFLO-PRO 1 topic

Description of the project:
There are two primary capabilities of the INFLO system; Dynamic Speed Harmonization (SPD-HARM) and Queue Warning (Q-WARN). Detailed descriptions of both can be found in the INFLO Concept Development and Needs Identification and the Report on Detailed Requirements for the INFLO Prototype documents. Below are brief descriptions of each application.

Speed Harmonization
Speed harmonization of traffic flows in response to downstream congestion, incidents, and weather or road conditions can greatly help to maximize traffic throughput and reduce crashes. Research and experimental evidence have consistently demonstrated that by that reducing speed variability among vehicles, especially in near-onset flow breakdown conditions, traffic throughput is improved, flow breakdown formation is delayed or even eliminated, and collisions and severity of collisions arereduced.

The INFLO SPD-HARM application concept aims to realize these benefits by utilizing connected vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) communication to detect the precipitating roadway or congestion conditions that might necessitate speed harmonization, to generate the appropriate response plans and speed recommendation strategies for upstream traffic, and to broadcast such recommendations to the affected vehicles.

Queue Warning
Queuing conditions present significant safety concerns, particularly with the increased potential for rear-end collisions. They also present disruptions to traffic throughput by introducing shockwaves into the upstream traffic flow. The INFLO Q-WARN application concept aims to minimize the occurrence and impact of traffic queues by utilizing connected vehicle technologies, including V2I and V2V communications, to enable vehicles within the queue event to automatically broadcast their queued status information (e.g., rapid deceleration, disabled status, lane location) to nearby upstream vehicles and to infrastructure-based central entities (such as the TMC) in order to minimize or prevent rear-end or other secondary collisions.

DFW-FRATIS-AOP No topics

Alternate Optimization Program 1.0 The alternate optimization program is a linear program written with the objective of minimizing empty (bobtail) moves for Southwest Freight, a participant in the Freight Advanced Traveler Information System (FRATIS) prototype test in Dallas-Fort Worth, Texas. The AOP was one application within the prototype system. The AOP requires 2 Excel or comma separate input file containing 30 columns; these input files were generated from Southwest Freight’s dispatching software [vendor: Trinium Technologies]. One file contains loaded orders, and the second file contained empty orders, but both files contained the same column structure. A blank template is included within the uploaded zip file. The user must select the input file from any location on their desktop. To account for Southwest Freight requirements, the program limits the number of orders that can be assigned to a single driver (route) to four, although this can be altered in the code. In addition, the program offers the user the flexibility to determine the number of drivers/routes that should be included in the daily plan. For Southwest Freight, they wanted to make sure a certain number of drivers would have work each day. This can also reduce the number of orders per route/driver. As described above, both the user interface and code were written in Java. There is no installer included with this package. Only Source code is provided.

MMITSS No topics

Description:
There are four major component of MMITSS field version: Intelligent Signal Control (I-SIG), Signal Priority (SP), Mobile Accessible Pedestrian Signal System (PED-SIG) and real-time performance observer (PERF-OBS).

Intelligent Signal Control (I-SIG) I-SIG provides real-time adaptive signal control to general vehicles by allocating green time of each phase intelligently. I-SIG takes vehicle trajectory data from BSMs and solve for optimal signal schedule in terms total delay minimization or total queue length minimization. The optimal signal schedule are implemented to Signal Controllers through NTCIP commands.

Signal Priority (SP) Signal priority provides priority to different modes of vehicles including transit, trucks and emergency vehicles. Priority eligible vehicles receive SPAT, MAP and SSM from RSE when they enter the DSRC range and generate SRMs. RSE considers all the active requests from different vehicle and solve for optimal signal schedule in terms of minimization of priority vehicle delay. The optimal signal schedule are implemented to Signal Controllers through NTCIP commands.

Mobile Accessible Pedestrian Signal System (PED-SIG) PED-SIG includes a smartphone application and two RSE applications that can send pedestrian signal request and provide assistance to disabled pedestrians. The RSE broadcast Pedestrians map information through WIFI and the smartphone application receives the MAP and sends pedestrian signal request. RSE will put pedestrian signal request to the Signal Controller.

Real-time Performance Observer (PERF-OBS) PERF-OBS monitors all the users on the road through BSMs and collects real-time performance data by movement by mode such as travel time, delay, and queue length etc.

CARMA 1 topic

The CVRP software provides an API to each of the TFHRC's CARMA vehicles (modified 2013 Cadillac SRX). Researchers can build project-specific control code on top of this API to study, for example, advanced ACC and driver assist systems. The software in this repository comprises four components that execute on two processors. The primary processor is a MicroAutobox II running dSpace, that houses:

CARMA platform Real-time
* Project-specific control code (not part of this repository)
*The secondary processor is a generic Ubuntu Linux PC that houses:

Data communication and extended driver interface
Log processor
The primary functions of these components are as follows:

CARMA real-time: this code parses input data from the CANbus and secondary processor and places the individual data elements into the data interface block, which can be read by the project-specific application (e.g. the PATH CACC code). It also reads project-specific outputs from the data interface block and packages them into properly formed messages and forwards them to the CANbus or secondary processor, as necessary.
Data communication and extended driver interface: is a web application that provides an extended driver interface (beyond the stock vehicle dashboard interface). This DVI is a web page that can be transmitted over wifi to a tablet mounted on the dashboard to provide experimental data feedback and get commands from the driver. It also communicates with the non-CANbus devices on the vehicle: two-way messaging with the DSRC on-board unit to pass BSMs; TORC controller to receive vehicle speed and to pass speed commands; and TORC Pinpoint location device to receive current vehicle position. Data from these devices is then reformatted as necessary and passed to the CARMA real-time component via Ethernet messages. Data from the CARMA real-time component (e.g. speed commands and BSMs) are passed to these devices as appropriate. As it exists in this repository, this component includes project-specific code (DVI presentation and data exchange with the MAB), so some packages will have to be modified for future projects.
Log processor: is a Python program running on the vehicle’s secondary processor responsible for formatting logs from the CACC control software on the MAB. The CACC control software sends various control parameters to the Log Processor every timestep via a UDP socket. The Log Processor parses this binary-formatted message into a human-readable CSV format more suited for post-processing and analysis. These files are stored in a subfolder of the Log Processer program’s working directory and are stored in files with timestamped names.

RW-PM No topics

The tool captures and analyzes applicable traffic mobility and road weather data continuously from multiple sources. This includes capturing road weather data from fixed weather stations (e.g., environmental sensor stations) and traffic mobility data from fixed speed sensors (e.g., inductive loop detectors) and/or subscription services. The Tool is capable of capturing also captures data from mobile sources such as road weather maintenance vehicles, connected vehicles, and drivers’ personal mobile devices. The data are transmitted wirelessly and stored in suitable traffic mobility, road weather, and RW-PM databases. The captured raw data are next analyzed by multiple processors operating in parallel and in real-time. One set of processors analyzes the raw data to compute local real-time traffic mobility and road weather performance “measures and metrics” and stores them in a “measures and metrics” database. Another set of processors analyzes the raw data and performance measures and metrics to develop real-time traffic control, road weather maintenance dispatch and motorist advisory recommendations. Traffic control and road weather maintenance managers personnel are alerted when DOT criteria for a weather event likely to degrade level of service (LOS) are met. Upon verification and authorization by the appropriate personnelmanagers:

Control and dispatch recommendations are deployed to traffic management and road weather maintenance systems;
Motorist advisories are deployed to connected vehicles and personal mobile devices; and
Road weather maintenance dispatch information and messages are issued to connected maintenance vehicles.
This process continues iteratively throughout the weather event, adjusting dynamically until the LOS returns to normal (e.g. the event concludes, the roads are cleared, and traffic mobility returns to normal). Following the event, system performance processors aggregate the data, measures, and metrics and assess performance and effectiveness outcomes for the entire event. The outcomes are then used by traffic control and road weather maintenance managers personnel to refine and optimize RW-PM strategies for implementation in responding to future weather events. System performance is evaluated seasonally and/or annually and strategies are updated to enhance seasonal and annual performance.

The LA-Gateway FRATIS demonstration project is focused on:

Improving communications and sharing intermodal logistics information between the truck drayage industry and port terminals such that terminals are less congested during peak hours;
Improving traveler information available to intermodal truck drayage fleets so that they can more effectively plan around traffic and port congestion; and
Employment of an optimization algorithm which will allow for the technologies to work together in a way which optimizes the drayage fleet deliveries and movements based on several key constraints (e.g., time of day, PIERPASS restrictions, terminal queue status, etc.).
The optimization algorithm used in this project is an extension on the algorithm used in the Cross Town Improvement Project (C-TIP) Drayage Optimization Proof of Concept Application. Due to the complexity of the drayage problem, the proposed optimization algorithm was developed through multiple iterations. In each iteration, the performance of the algorithm was validated and tested to ensure that the algorithm was working properly. The algorithm performance has been tested over a set of different problems ranging from well-known benchmark problems to specially customized ones.

DIRECTView is a visualization application designed to visualize the performance measures generated during simulations using DIRECT software with options to turn on and turn off scenarios. DIRECT stands for Dynamic Intermodal Routing Environment for Control and Telematics and is a simulation package utilized for multi-modal traffic simulation. Please note that DIRECT is not provided with this repository (users interested in using DIRECT software are encouraged to contact Dr. Khaled Abdelghany of Southern Methodist University at This email address is being protected from spambots. You need JavaScript enabled to view it. for a free executable version). DIRECTView uses xml-based output files that are generated by DIRECT to generate visualization graphics.
While originally developed for the Dallas Integrated Corridor Management (ICM) Analysis, Modeling and Simulation (AMS) effort, the Dynamic Mobility Applications (DMA) – Active Transportation and Demand Management (ATDM) AMS Testbed project, sponsored by the U.S. DOT, used this tool for evaluating DMA and ATDM strategies, applications, and concepts. The DIRECT View download package provides sample xml files for users to use with DIRECTView. These files are provided within the “INPUT” folder in the repository and are the outputs that were generated during AMS Testbed Simulation Analysis. In addition, downloaders can use the code to tailor visualizations of outputs produced by any simulation software by modifying the xml-based parser within the code.

D-RIDE-AMS No topics

Under the AMS project, Arizona State University developed a prototype Dynamic Ride Sharing application that provides drivers and riders with the flexibility of making real-time transportation decisions and aims at increasing the use of non-transit ride-sharing options including carpooling and vanpooling. The application is coded as a Vehicle Routing Problem with Pickup and Delivery with Time Windows (a.k.a., VRPPDTW) problem which typically requires the use of complex optimization solvers even for a limited number of agents on medium scale networks.

This algorithm is designed to calculate the pick-up and drop-off sequence for a given set of vehicles to transport given passengers. Each passenger has a specific time window requirement for picking up and dropping off. This algorithm can minimize the number of required vehicles and travel the shortest distance to meet all the passengers' requirements.

Glidepath No topics

The GlidePath application is vehicle on-board software that provides level 1 (longitudinal) control for a modified 2010 Ford Escape at the Saxton Lab while it transits an intelligent, signalized intersection. The software's objective is to maximize fuel economy as the vehicle passes through the intersection by minimizing speed changes. It receives and interprets information about the signal operation via messages broadcast by the roadside infrastructure via Dedicated Short Range Communication (DSRC) radio. The messages are Signal Phase and Timing (SPAT message) and a map of the intersection geometry (MAP message). With this information and precise knowledge of vehicle location and state, the software computes an optimal speed trajectory to approach and depart the intersection in an eco-friendly manner.

If you do not have an account, you may submit an account registration request by following the 'create an account' link shown below the login form. All collaboration requests will be evaluated by the OSADP administrators and the Open AWAM project manager. You will be notified if/when your request is granted.

Project Information:

AWAM stands for Anonymous Wireless Address Matching, and is a generic term for Bluetooth- or WiFi- based travel time data collection systems. The OpenAWAM uses field devices, called nodes running Linux software, to collect Bluetooth addresses and pass the data over an agency-owned data telecommunication network to a central computer. This central computer matches and processes these addresses to develop travel times. Travel times are then developed for roadway segments and displayed on a map and/or disseminated. Anonymization is accomplished by generating and passing a CRC32 checksum of the address in the field; the addresses are never recorded.

The software project is cross-platform (Windows or Linux) and consists of Python and Javascript files for installation, plus instructions for assembling and installing field nodes from off-the-shelf components costing less than $200 each for a complete node. No software development is required for the field nodes because existing open-source software provides all necessary functionality. The Moreno Valley test bed currently consists of four field nodes which have been operational for more than one year.
