center the word as in the title

Question

I want to move the word up after \huge as in the title in the screenshot below. I am trying to use the stuff in the title argument since I do not want to add a name or date and \maketitle generate a big space if I add \date{} so I decided to get through with this approach. I will delete \title{} and \maketitle after managing it.

code:

\documentclass[paper=a4, fontsize=11pt]{scrartcl}   % 
\usepackage[T1]{fontenc}
\usepackage{fourier}
\usepackage[ngerman, english]{babel}
\usepackage[protrusion=true,expansion=true]{microtype}      
\renewcommand{\baselinestretch}{1.5}
\newcommand{\horrule}[1]{\rule{\linewidth}{#1}}     % 
\newcommand{\twoobjects}[2]{%
  \centering \leavevmode\vbox{\hbox{#1}\nointerlineskip\hbox{#2}} %
}
\usepackage[backend=bibtex]{biblatex}

\addbibresource{references.bib}

\title{
        %\vspace{-1in}  
        \usefont{OT1}{bch}{b}{n}
        \normalfont \normalsize \textsc{SmartBusTraffic: Estimation of Bus positions based on Crowd Sourcing Monitoring} \\ [25pt]
        \horrule{0.5pt} \\[0.4cm]
        \huge Handbook
        \horrule{2pt} \\[0.5cm]
        \date{}
}


\begin{document}

        \begin{center}
                \usefont{OT1}{bch}{b}{n}
        \normalfont \normalsize \textsc{SmartBusTraffic: Estimation of Bus positions based on Crowd Sourcing Monitoring} \\ [25pt]
        \end{center}


        \horrule{0.5pt} \\[0.4cm]
        \begin{center}
        \huge Handbook \\
        \end{center}

        \horrule{2pt} \\[0.5cm]

Use \centering instead of \begin{center}...\end{center}, but use it within a group, i.e. a {...} pair, for example. The center environment adds some vertical space before and after the centered content.

A. Ellett made a good comment: The blank line (or a \par) before closing the group is needed by \centering, otherwise there would be no centering (for this effectively one - line text).
