DLSim 0.2.1

demo

DLSim

DLSim is an open-source, cross-platform, lightweight, and fast Python traffic assignment tool adopted and modified from ASU Trans+AI Lab

Installation

DLSim has been published on PyPI, and can be installed by using package manager pip to install DLSim.

pip install dlsim

If you need a specific version of DLSim, say, 0.2.1,

$ pip install dlsim==0.2.1

If you want to test the latest features of DLSim, you can build the package from sources and install it offline, where Python 3.x is required.

# from the root directory of DLSim
$ python setup.py sdist bdist_wheel
$ cd dist
$ python -m pip install dlsim-version.tar.gz

Usage

Find the shortest path (based on distance) and output it in the format of a sequence of node/link IDs.

import DLSim as ds
import time

network = ds.Network()

ds.g_ReadInputData(network.node_list, 
                   network.link_list, 
                   network.agent_list,
                   network.internal_node_seq_no_dict,
                   network.external_node_id_dict,
                   network.agent_td_list_dict,
                   network.zone_to_nodes_dict,network.node_seq_to_link_seq)
network.allocate()

ds.begin_time = time.time()

ds.g_find_shortest_path_for_agent(network)
ds.g_TrafficSimulation(network.node_list, network.link_list, 
                       network.agent_list, network.agent_td_list_dict)
ds.end_time = time.time()
ds.g_OutputFiles(network.link_list, 
                 network.agent_list, 
                 network.external_node_id_dict)
