wrong, it contains the following comments which are clearly sysvinit/lsb-headers
you need to install it in the correct folder aka /etc/init.d/

# Provides:          Traffic Server
# Required-Start:    $local_fs $remote_fs

on Fedora clearly "/usr/bin/traffic_cop" is started which *is* a
binary resulting in 3 processes and traffic_cop is also repsonsible
to restart "/usr/bin/traffic_server" which is *alo* a binary

so if you have a chance to use systemd ignore the shellscript

[root@proxy:~]$ cat /usr/lib/systemd/system/trafficserver.service
Description=Apache Traffic Server
After=network.service dnsmasq.service

ExecReload=/usr/bin/traffic_line -x
